[Purpose] Limitations in performing the 180°-turning increase the risk of falls and disabilities in stroke patients. The aim of this study was to characterize and compare the 180°-turning between people with and without stroke, considering the direction towards which they turned. [Subjects and Methods] Fourteen subjects with stroke and 14 matched healthy controls performed the 180°-turning twice while walking: towards the self-selected, and the opposite directions. The turning performances were recorded using three video cameras. The videos were randomly analyzed by a single examiner, who characterized the turning, while considering the time required to complete the task, the number of steps, balance, and turning type. Friedman Tests and ANOVA (2 × 2) were used to compare the groups and turning direction factors (turning towards the self-selected versus opposite sides, and towards the paretic/non-dominant versus non-paretic/dominant sides). [Results] No interaction between the groups and turning directions, and no significant differences between the turning directions were found. However, significant differences were found between the groups for all variables used to characterize the turning performance, except for the type of turning. [Conclusion] Stroke subjects demonstrated poor performance on the 180°-turning, regardless of the turning direction. Duration, number of steps, and balance loss indicated difficulties in turn performance.

[Purpose] This study applied active rehabilitation therapy to muscular back strength and assessed the subjective pain degree in chronic low back pain patients. [Subjects and Methods] Subjects were randomly assigned to two groups: experimental (n=8) and control (n=8). The experimental group performed two types of rehabilitation therapy programs four times per week for eight weeks. The rehabilitation program was based on the Korea Occupational Safety and Health Agency’s program. There were several types of stretching and strengthening. Back strength was measured using the Back Muscle Dynamometer TKK-5402. The visual analog scale score, selected to measure degrees of subjective pain, was used to assess treatment efficacy. [Results] For the experimental group, muscular back strength increased from 133.90 ± 11.84 kg before exercise to 145.59 ± 14.49 kg after exercise. In the control group, muscular back strength decreased from 133.92 ± 3.84 kg before exercise to 133.90 ± 5.81 kg after exercise. In the experimental group, the visual analog scale score for subjective pain decreased from 6.63 ± 0.52 before exercise to 5.75 ± 0.46 after exercise; in the control group, it decreased from 5.61 ± 0.52 before exercise to 5.61 ± 0.52 after exercise. [Conclusion] Active rehabilitation therapy is a positive intervention that can provide relief from back pain.

[Purpose] A scalp massage was conducted on female office workers divided into a 15 minute group and 25 minute group and its effect on stress hormone, blood pressure and heart rate was analyzed in order to provide a theoretical rationale to apply scalp massage as stress therapy. [Subjects and Methods] A scalp massage was applied to 34 female office workers twice a week for a total of 10 weeks; the subjects were classified into 15 min., 25 min. and control groups, and their stress hormone levels, blood pressure and heart rate were evaluated. [Results] Significant differences in norepinephrine, cortisol and blood pressure (SBP & DBP) were found in terms of interaction by time interval and between groups. [Conclusion] As a result of applying scalp massage to female office workers for 15 and 25 minutes, positive effects were observed on stress hormone, blood pressure and heart rate. Therefore, scalp massage can be used for stress control with no spatial or time limit.

[Purpose] This study is to analyze bioimpedance parameters and occupational assessment for severe stroke patients with upper extremity hemiplegia. [Subjects and Methods] Experimental subjects were 20 hemiplegic stroke patients receiving rehabilitation therapy between November to October, 2015. Prediction marker (PM), and phase angle (θ), a nd characteristic frequency (fc) were measured using bioelectrical impedance spectroscopy (MultiScan 5000). Bioelectrical impedance vector analysis (BIVA) was also obtained from the bioimpedance data. Then, these values were compared with occupational assessment tools. [Results] A significant differences in PM, θ, fc, and BIVA were observed between paretic region and non-paretic region of 5 severe stroke patients. These results were in good agreement with occupational assessment (pinch and hand grip strength, and ADL by MBI). [Conclusion] There were significant differences in impedance parameters between paretic region and non-paretic region of 5 severe stroke patients with upper extremity hemiplegia. Thus, the BIA could be useful tool for evaluating hemiplegic stroke patients receiving the rehabilitation therapy in the clinical application.

[Purpose] This study aimed to examine whether or not friction massage of the popliteal fossa would be effective for achieving dynamic changes in muscle oxygenation and ankle flexibility. [Subjects and Methods] Twelve healthy male university students participated. Before and after friction massage, dynamic changes in muscle oxygenation and ankle flexibility were measured by near-infrared spectroscopy to evaluate its efficacy. [Results] Oxygenated hemoglobin was significantly higher after as compared to before massage. The range of ankle dorsiflexion tended to increase after massage. [Conclusion] These results suggest that friction massage of the popliteal fossa stimulates venous return in the lower leg.

[Purpose] The purpose of this study is to analyze changes in movements of the neck, trunk and hip according to foot position while performing sit-to-stand (STS) exercises from a height-fixed chair. [Subjects and Methods] The study subjects consisted of 22 university students (12 males and 10 females). STS was conducted using a height-fixed chair at three positions: symmetric foot position, right foot position, and left foot position. Through three-dimensional motion analyzer, the movements of the neck, trunk, and hip were analyzed. [Results] While performing STS, the height was more influential on changed in angle of the neck, trunk, and hip. Moreover, when the height of the chair and the height of the subject were not matched correctly, more effective STS could be achieved when both of feet were laid symmetrically rather than at the other two positions. [Conclusion] It is necessary to employ an appropriate chair height that is matched with the height of the patients when therapy using STS is performed.

[Purpose] To explore data on functioning in the medical records of patients with stroke by linking them to the ICF. [Subjects and Methods] The admission and discharge summaries of patients’ electronic medical records (EMRs) were investigated. Information on functioning included in the summaries were mapped into the ICF. Each of the linked categories of ICF was analyzed using frequency and percentage analysis. [Results] Thirty stroke patients’ records were evaluated. A total of 1,832 items on functioning in the EMRs were found to be linked to eighty-five categories of the ICF. The majority of those categories (52.9%) belonged to the body function domain, whereas only 8.2% were environment factors. Categories in the domain of activity and participation, and body structure were found to be 22.4% and 16.5% respectively. In each domain, the most frequently found categories were muscle power function (b730), structure of brain (s110), walking (d450), and products or substances for personal consumption (e110). [Conclusion] It was found that the admission and discharge summary in the current medical records of patients with stroke contained much noticeable information on functioning and the data on functioning may be linked to the ICF. Further study is needed to adapt ICF in Korean clinical settings.

[Purpose] The purpose of this study was to investigate the effectiveness of home-based exercise programs for low back pain (LBP) patients. [Subjects and Methods] The study subjects were 49 volunteer chronic LBP patients. Home-based exercises that had been specifically modified for the individual patients were prescribed for a period of four weeks, and the volunteers were asked to return for a control evaluation at the end of this period. Exercise adherence and correct performance, pain intensity, disability, endurance, and flexibility were compared between pre- and post intervention, and correlations between exercise adherence and correct performance with, pain intensity score, endurance, disability, and flexibility were investigated. [Results] Twenty-eight patients (57.14%) did not return for the control evaluation. The mean age of the patients who participated in this control test was 43.24 ± 10.89 years. The adherence rate of the home exercise program was 54.10 ± 26.01%, and the correctly performed execises score was 2.7 ± 1.9. All of the parameters had improved at the final evaluation; however, there was no correlation among the parameters. [Conclusion] Clinicians should be aware of the patient’s adherence level when recommending home-based exercises, and should also realize that exercises might be performed inaccurately in an unsupervised environment.

[Purpose] Association of ACTN3 polymorphism with bone mineral density and the physical fitness of elderly women is still unclear. Therefore, this study investigated the association between ACTN3 genotype and bone mineral density, and the physical fitness of elderly women. [Subjects and Methods] Sixty-eight elderly women (67.38 ± 3.68 years) were recruited at a Seongbuk-Gu (Seoul, Korea) Medical Service Public Health Center. Measurements of physical fitness included muscle strength, muscle endurance, flexibility, agility, balance and VO₂max. Bone mineral density (BMD), upper limb muscle mass, lower limb muscle mass, percent body fat and body fat mass for the entire body were measured by dual-energy X-ray absorptiometry and an analyzer. Genotyping for the ACTN3 R577X (rs1815739) polymorphism was performed using the TaqMan approach. [Results] ACTN3 gene distribution of subjects were in the Hardy-Weinberg equilibrium (p=0.694). The relative bone mineral density trunk, pelvis and spine differed significantly among the ACTN3 genotypes. There were no significant differences among bone mineral densities of the head, arms, legs, ribs and total, but the RR genotype tended to be higher than other genotypes. Physical fitness was not significantly different among the ACTN3 genotypes. [Conclusion] These results suggest that ACTN3 gene polymorphisms could be used as one of the genetic determinants of bone mass in elderly women, and in particular, they indicate that individuals with the RR genotype have higher BMD and bone mineral composition.

[Purpose] This study investigated whether it is possible to predict return to home at discharge from a rehabilitation hospital in Japan using the home care score of patients with cerebrovascular or osteoarticular disease and low activities of daily living at admission. [Subjects and Methods] The home care score and functional independent measurement were determined for 226 patients at admission and at discharge from five hospitals, and receiver operating characteristic analyses were conducted. [Results] The home care score cutoff point for the prediction of return to home at admission and at discharge was 11, and the area under the curve was more than 0.8. The area under the curve of the home care score was 0.77 for patients with low activities of daily living and within this group, the probability of return to home was approximately 50%, as predicted by the functional independent measurement. The home care score increased after receiving intervention at a rehabilitation hospital. [Conclusion] The home care score is useful for the prediction of return to home from a rehabilitation hospital, although prediction using the functional independent measurement is difficult for patients with low activities of daily living. Moreover, comprehensive interventions provided by the rehabilitation hospitals improve the ability to provide home care of the patient’s family, which is assessed by the home care score.

[Purpose] This study sought to examine the effects of position change on lumbar pain and discomfort of Korean patients after invasive percutaneous coronary intervention. [Subjects and Methods] The participants consisted of 48 patients (experimental: n=24, control: n=24) who underwent invasive coronary intervention (Percutaneous Coronary Intervention) in K hospital, Seoul, Korea. A randomized controlled trial design was used. Position changes as the experimental treatment were sequenced as follows: supine position for one hour after removal of the catheter; 30-degree bed-elevated lateral position for one hour; 30-degree bed elevation for one hour; and finally 30-degree bed-elevated lateral position for one hour. The thirty degree bed-elevated lateral position was intended to press on the surgical site. Measures used were the general characteristics form, Visual Analogue Scale for lumbar pain, and discomfort scale. [Results] There were significant differences on lumbar pain and discomfort of Korean patients after invasive coronary intervention between the experimental and control groups. [Conclusion] Position change was an effective intervention for decreasing lumbar pain and discomfort of Korean patients after invasive coronary intervention. Health professionals need to consider an array of methods including position change for patients after invasive coronary intervention.

[Purpose] This study’s purpose was to identify abduction angles of the shoulder joint that can provide effective infraspinatus muscle exercises while minimizing the muscle activity of the posterior deltoid muscle. [Subjects and Methods] The subjects of this study were 15 healthy young students in their 20s. Subjects adopted a standing position and performed shoulder external abduction while pushing their hands against the wall. The current research was undertaken to compare the activity of the infraspinatus muscle and the posterior deltoid muscle at abduction angles of 45, 90 and 135° of the shoulder joint during closed kinetic chain exercises. [Results] A activity of the infraspinatus muscle showed no statistically significant differences. The activities of posterior deltoid muscle were greater at the angle of 45° than at 90 and 135°. [Conclusion] These results indicate that to strengthen the infraspinatus, shoulder external rotation exercises at abduction angles of the shoulder joint greater than 45° are more effective.

[Purpose] The purpose of this study was to analyze the effect of gluteus medius activity strengthening due to squat with isometric hip adduction and hip abduction in side-lying exercise on knee joint function index and pain in meniscal surgery patients. [Subjects and Methods] This study selected sample of 26 patients who had meniscal surgery more than 4 weeks ago. The patients were divided into squat with isometric hip adduction exercise group I (n=8), hip abduction in side-lying exercise group II (n=9), and combined exercise group III. The lysholm score was used to evaluate knee joint function and visual analog scale was used to evaluate pain index of knee joint. [Results] Two-way repeated measures ANOVA was used to analyze the lysholm score and visual analog scale and showed significant interaction between the groups and durations. [Conclusion] Strengthening vastus medialis oblique and gluteus medius improved functional recovery and pain reduction of knee joint in meniscal injury surgery patients. Gluteus medius strengthening exercise is essential to meniscal injury surgery patients and should be included in rehabilitation program in early stages to be conducted systematically.

[Purpose] The aim of the present study was to compare the effect of pre-operative and post-operative physical therapy versus post-operative physical therapy alone on pain and recovery of function after total knee arthroplasty. [Subjects and Methods] Fifty patients (18 males and 32 females) ranging in age from 48 to 80 years (mean 63.28, SD 9.44) participated in a 6-week two-arm randomized rater-blinded trial. One group received pre- and post-operative physical therapy whereas the other group received only post-operative physical therapy. Pain and function were measured with a visual analogue scale and a lower extremity functional scale at baseline (pre-operative) as well as week 3 and week 6 post-operative. [Results] The differences in pain intensity and functional score at week 3 and week 6 post-operative remained statistically insignificant between the two groups. [Conclusion] The reduction of pain and recovery of function was similar in subjects who received pre- and post-operative physical therapy and those who received only post-operative physical therapy after total knee arthroplasty. Additional pre-operative physical therapy did not bring about any further improvement in pain intensity or recovery of function after total knee arthroplasty.

[Purpose] The aim of this investigation was to determine the effects of 4 weeks of fast expiration exercises performed without pressure on respiratory muscle strength. [Subjects and Methods] Respiratory muscle strength of the training group that performed fast expiration exercises (n=12) was compared with that of a control group that performed no exercises (n=12). The fast expiration exercises were performed using a peak expiratory flow meter device and consisted of 20 fast expiration exercises performed 3 times per week for 4 weeks. Maximal expiratory and inspiratory pressures were evaluated as respiratory muscle strength using a spirometer pre- and post- intervention. [Results] There were significant increases in maximal expiratory pressure from 76.9 ± 29.1 to 96.1 ± 37.5 cmH₂O and maximal inspiratory pressure from 80.8 ± 36.6 to 95.3 ± 37.6 cmH₂O in the training group, but there was no significant difference in respiratory muscle strength between pre- and post-intervention in the control group. [Conclusion] Fast expiration exercises may be beneficial for increasing respiratory muscle strength. The findings of this study should be considered when prescribing a variation of the expiratory muscle strength training, as part of a pulmonary rehabilitation program.

[Purpose] This study investigated the factors associated with the recovery rate of activities of daily living of elderly patients hospitalized for acute medical illness. [Subjects and Methods] A total of 238 elderly patients were enrolled in this study. The main outcome measure was the functional independence measure score which was used as an assessment of activities of daily living. The participants were divided into 2 groups based on their activities of daily living before onset: the independent group and the partially dependent group. The participants of each group were further divided into 2 subgroups based on recovery rates of activities of daily living: the high-recovery group (80%) and the low-recovery group (<80%). The factors associated with the recovery rate were examined using multivariate logistic regression analysis. [Results] The factors associated with the recovery rate were: days of inactivity and cognitive status at the start of rehabilitation for the independent group, and days of inactivity and nutritional status at the start of rehabilitation for the partially dependent group. [Conclusion] The results of this study suggest that the important factors for return to normal activities of daily living are: days of inactivity and cognitive status for the independent group; and days of inactivity and management of nutrition for the partially dependent group.

[Purpose] The purpose of this study was to examine the effects of forearm elastic taping on grip and wrist flexor muscle strength. [Subjects and Methods] This was a single-blind, crossover study. This study selected 40 healthy subjects with no history of orthopedic disorders and was conducted after consent to participate was obtained. Grip and wrist flexor muscle strength of subjects were assessed by a handheld dynamometer and a Commander Muscle Tester, respectively, with forearm elastic taping or nonelastic taping. [Results] After application of forearm elastic taping, grip strength and wrist flexor muscle strength significantly increased compared with the nonelastic taping group. [Conclusion] Application of forearm elastic taping is considered to have positive effects on improving wrist and grip strength.

[Purpose] This study investigated the effect on activities, shoulder muscle fatigue, upper limb disability of two exercise types performed by patients in the post- immobilization period of rotator cuff repair. [Subjects and Methods] The intervention program was performed by 20 patients from 6 weeks after rotator cuff repair. Ten subjects each were randomly allocated to a group performing open kinetic chain exercise and a group preforming closed kinetic chain exercise. Muscle activity and median frequency were measured by using sEMG and the Upper Extremity Function Assessment before and after conducting the intervention and changes in the results were compared. [Results] There was a significant within group increases in the activities of the shoulder muscles, except for the posterior deltoid. The median power frequencies (MFD) of the supraspinatus, infraspinatus and anterior deltoid significantly increased in the open kinetic chain exercise group, but that of the posterior deltoid decreased. There were significant differences in the changes in the upper limb disability scores of the two groups, in the shoulder muscle activities, except for that of the posterior deltoid, in the comparison of the change in the muscle activities of the two groups, and in the MDFs of all shoulder muscles. [Conclusion] The Median power frequencies of all these muscles after closed kinetic chain exercise increased indicating that muscle fatigue decreased. Therefore, research into exercise programs using closed kinetic chain exercises will be needed to establish exercise methods for reducing muscle fatigue.

[Purpose] The aims of this study were to verify the effects on upper limb circumferences and total body extracellular water of 10 weeks of Nordic Walking (NW) and Walking (W), both alone and combined with a series of exercises created for breast cancer survivors, the ISA method. [Subjects and Methods] Twenty breast cancer survivors were randomly assigned to 4 different training groups and evaluated for upper limb circumferences, total body and extracellular water. [Results] The breast cancer survivors who performed NW, alone and combined with the ISA method, and Walking combined with the ISA method (but not alone) showed significantly reduced arm and forearm circumferences homolateral to the surgical intervention. [Conclusion] For breast cancer survivors, NW, alone and combined with the ISA method, and Walking combined with the ISA method should be prescribed to prevent the onset and to treat light forms of upper limb lymphedema because Walking training practiced alone had no significant effect on upper limb circumference reduction.

[Purpose] This study aims to investigate the effects of upper-limb exercises on the respiratory functions of stroke patients. [Subjects and Methods] This study was performed with 25 stroke patients. The subjects were divided into the control group (n=12) which did not perform upper arm training and the experimental group (n=13) which conducted upper arm training. Forced vital capacity and forced expiratory volume in the first second, both of which are used in this study, are well-known indicators of respiratory capabilities. Peak cough flow is used to indicate cough capability. [Results] Concerning changes in forced vital capacity, forced expiratory volume in the first second and the peak cough flow of each group after the exercise, while the control group did not show significant differences, the experimental group showed statistically significant increases. [Conclusion] The results of the study indicate that exercise programs that increase the mobility of upper limbs and increase muscular strength have the effect of normalizing vertebral alignment for stroke patients, and thus can provide effective interventions for improving respiratory function.

[Purpose] This study was conducted to quantify the effect of sling exercise therapy in the recovery of lumbosacral sagittal alignment (LSA) and in the control of low back pain. [Subjects and Methods] A total of 102 chronic low back pain patients were divided into two groups, a physical therapy group and a sling exercise group. In both groups, programs were conducted thrice a week for twelve weeks. With respect to LSA, pelvic tilt (PT), sacral slope (SS), and pelvic incidence (PI) were measured with plain radiography. Pain was measured on a visual analogue scale (VAS). [Results] Differences were found in visual analogue scale, delta score of visual analogue scale, pelvic tilt, delta score of pelvic tilt, and delta score of pelvic incidence between sling exercise therapy and physical therapy groups. VAS, pelvic tilt, and pelvic incidence was positively changed after sling exercise. However, only the visual analogue scale was found to be improved after physical therapy. [Conclusion] Sling exercise therapy and physical therapy were effective in reducing pain. However, pelvic tilt and pelvic incidence were positively changed after sling exercise therapy for Lumbosacral Sagittal Alignment, but were unchanged after physical therapy. Therefore, sling exercise therapy is more effective than physical therapy for the recovery of Lumbosacral Sagittal Alignment in patients with chronic low back pain.

[Purpose] The aim of this study was to examine the effect of resistance exercise on carotid intima-media thickness, luminal diameter, peak systolic flow velocity, end diastolic flow velocity, and wall shear rate in healthy elderly men. [Subjects and Methods] Thirty healthy elderly men (age ≥65 years) were randomly divided into a control (n=15) and resistance exercise (n=15) groups. The 24-week exercise intervention consisted of 3 days of resistance exercise per week using an elastic band per week. Body composition, physical function, blood pressure, and carotid variables were measured at baseline and after 24 weeks. [Results] Body fat percent, skeletal muscle mass, systolic blood pressure, grip strength, arm curl, chair stand up, sit and reach, maximum walking speed, time up and go, and two-minute step test showed significant interaction. Peak systolic flow velocity, end diastolic flow velocity, and wall shear rate also showed significant interaction. [Conclusion] A 24-week resistance exercise program, using elastic bands, effectively improves carotid flow velocity and wall shear rate in healthy elderly men.

[Purpose] The aim of this study was to investigate the association between magnetic resonance imaging (MRI) findings in patients with adhesive shoulder capsulitis and the therapeutic effect of capsular distension. [Subjects and Methods] We retrospectively reviewed the medical records of 57 patients who underwent capsular distension therapy after a diagnosis of adhesive capsulitis with clinical and MRI scans. Axillary joint capsular thickness by MRI was graded as I (≤3.6 mm), II (3.7–4.2 mm), and III (≥4.3 mm). Subcoracoid fat obliteration of the rotator interval was graded subjectively as absent, partial, and complete. [Results] Capsular thickness and fat replacement were correlated with passive range of motion (PROM) and pain score on a visual analog scale (VAS) by analysis of variance with a Bonferroni correction before treatment and by analysis of covariance with a Bonferroni correction after treatment. Visual analog scale (VAS) for patients with all grades decreased significantly after treatment and passive range of motion (PROM) for patients with all grades improved. No difference was detected between grades. [Conclusion] Although MRI is useful to evaluate adhesive capsulitis, MRI findings of shoulder did not predict the prognosis after capsular distension treatment.

[Purpose] The purpose of this study was to investigate the correlation between respiratory muscle strength and cough capacity in stroke patients. [Subjects and Methods] Forty-two stroke patients were assigned to 2 different groups (intervention group=21, control group=21). Both groups participated in a conventional stroke rehabilitation program, with the intervention group also receiving respiratory muscle training for 20 to 30 minutes a day, 3 times a week for 8 weeks. Respiratory muscle strength (maximal inspiratory pressure, maximal expiratory pressure), forced vital capacity, and cough capacity were measured. [Results] The intervention group showed significant increases in maximal inspiratory pressure, maximal expiratory pressure, forced vital capacity, and cough capacity. The change in maximal inspiratory pressure, maximal expiratory pressure, and forced vital capacity showed a significant correlation with cough capacity, with maximal expiratory pressure showing the highest correlation. [Conclusion] The present study showed that the increase in maximal expiratory pressure plays an important role in improving the cough capacity of stroke patients.

[Purpose] The purpose of the study was to investigate the postural control and cognitive performance of older adults when stepping backward with and without a concurrent cognitive task. [Subjects and Methods] Thirty young adults and twenty-eight older adults (mean age=21.3 ± 1.2 and 72.2 ± 5.7 years, respectively) were recruited. Participants were asked to step backward and then maintain a single-leg stance for 10 seconds with and without a concurrent auditory response task. The reaction time and error rate while performing the cognitive task were recorded. Postural stability after stepping back was measured in terms of total sway path and total sway area. [Results] The older subjects had significantly longer reaction times and higher error rates in both single- and dual-tasking. When dual-tasking, both groups had significantly longer reaction times than when single-tasking. Only the older adults showed significantly higher error rates. The older adults also had significantly longer total sway paths and larger total sway areas of single-leg stance after stepping back. Neither group showed a significant difference in total sway path and sway area between single- and dual-tasking. [Conclusion] Older adults have poorer cognitive performance and postural stability during both single- and dual-tasking. They tend to prioritize postural control over cognition in dual-tasking.

[Purpose] This study is designed to compare the effects of abdominal drawing-in exercise and myofascial release on pain, flexibility, and balance of elderly females. [Subjects and Methods] Forty elderly females aged 65 or older who had complained of low back pain for three months or longer were selected as the subjects. They were randomly and equally assigned to either an abdominal drawing-in group or a myofascial release group. The subjects conducted exercise three times per week, 40 minutes each time, for eight weeks. As evaluation tools, visual analogue scale for pain, remodified schober test for flexibility, and upright posture with eye opening on hard platform, upright posture with eye closing on hard platform, upright posture with eye opening on soft platform, upright posture with eye closing on soft platform using tetrax for balance were used. [Results] The abdominal drawing-in exercise group saw significant difference in pain and balance after the exercise compared to before the exercise. The myofascial release group saw significant difference in pain and flexibility after exercise compared to before the exercise. [Conclusion] The above study showed that abdominal drawing-in exercise affected elderly females regarding pain and balance and myofascial release influenced their pain and flexibility.

[Purpose] To evaluate the sensitivity and specificity of the Safe Driving Behavior Measure and the Driving Habits Questionnaire in community-dwelling older self-drivers. [Subjects and Methods] Forty-five older participated in this study, to measure the Safe Driving Behavior Measure and the Driving Habits Questionnaire. Sensitivity and specificity were calculated along with cut-off values and overall accuracy of each measure as determined by the participants operating characteristic curve and the area under the curve. Multivariate logistic regression analysis was employed to identify predictors of driving abilities. [Results] The sensitivities were 0.538 for Safe Driving Behavior Measure, and 0.577, 0.423, and 0.615 for the difficulty, crash and citations, and driving space on domains of the Driving Habits Questionnaire, respectively. The specificities of the person-vehicle domain, person-environment domain, and person-vehicle-environment domain of the Safe Driving Behavior Measure were 0.474, 0.526, and 0.421, respectively, while the Driving Habits Questionnaire domains, the specificities of difficulty, crash and citations, and driving space were 0.526, 0.211, and 0.421, respectively. [Conclusion] The results of this study suggest that factors related to the accident history of older self-drivers were not well-explained, although the Safe Driving Behavior Measure and Driving Habits Questionnaire domains have the potential to determine driving-related accident history.

This study aimed to evaluate the effects of green tea and supervised exercise training interventions on improvement of disease activity and bone metabolism markers in rheumatoid arthritis patients. [Subjects and Methods] One-hundred and twenty subjects who had a mean age of (60.7 ± 2.53 years) and had been diagnosed with rheumatoid arthritis at least ten years previously were randomly included in this study. Patients were treated with infliximab, green tea, or a supervised exercise program for six months. Disease activity markers as well as antioxidant activity of green tea extracts were estimated before supplementation using in vitro assays. [Results] Rheumatoid arthritis patients treated with green tea for 6 months alone or in combination with infliximab or an exercise program showed significant improvement in disease activity parameters, including C-reactive protein, and erythrocyte sedimentation rate, swollen and tender joints counts, and modified Stanford Health Assessment Questionnaire score, along with an increase in serum levels of bone resorption markers, i.e., deoxypyridinoline, amino-terminal telopeptide of type 1 collagen, and bone alkaline phosphatase, at 6 months of after initial treatment. The European League Against Rheumatism and American College of Rheumatology scores revealed more clinical improvement in the disease activity of rheumatoid arthritis patients treated with green tea along with exercise compared with rheumatoid arthritis patients treated with infliximab or exercise combinations. This may have been due to the higher potential antioxidant activity of green tea (89.6% to 96.5%). [Conclusion] Both exercise and green tea interventions appeared to be beneficial as nondrug modulates for rheumatoid arthritis disorders.

[Purpose] The purpose of this study was to investigate the influence of sacral sitting in a wheelchair on contact pressure on the buttocks and back, and shear force on the ischial region. [Subjects and Methods] Twenty-six healthy adults assumed two postures while seated in a wheelchair: a basic sitting posture, and sacral sitting with the pelvis tilted posteriorly and the ischium slid forward by 5 cm relative to its position in the basic sitting posture. The inclination angle of the sagittal pelvic line, contact pressures and contact areas on the buttocks and back, and the shear force generated by sliding the ischial region forward were measured. [Results] Posterior pelvic tilt was significantly greater during sacral sitting. Maximum contact pressures on the buttocks and ischial region were significantly lower during sacral than during basic sitting. However, maximum contact pressure on the back, the contact areas of the buttocks and back, and the shear force generated by sliding the ischial region forward were significantly greater during sacral sitting. [Conclusion] Sacral sitting in a wheelchair increases the maximum contact pressure on the back, contact areas of the buttocks and back, and the shear force generated by sliding the ischial region forward.

[Purpose] Support moment was defined as the sum of ankle plantar flexion, knee and hip extension moments. There are some mechanical relationships among the 3 joints. If these relationships were understood, it might be possible to determine which joint should be strengthened to improve gait. The aims of this study were to examine the mutual relationship among kinetic variables of the 3 joints during different phases. [Subjects and Methods] Twenty-five healthy subjects volunteered for this study. They were asked to walk on a platform at a self-selected speed. Correlation coefficients between support moment and vertical ground reaction force were calculated for each subject. Pearson correlation analysis was performed among the 3 joint moments and between each joint moment and vertical ground reaction force. [Results] Knee and hip extension moments showed negative correlation throughout the stance. Ankle moment had a positive with hip but a negative correlation with knee moment except in the initial contact and pre-swing. Hip moment in the initial contact, knee moment in the loading response, and ankle moment from the terminal stance to pre-swing had a high correlation with vertical ground reaction force. [Conclusion] The results may indicate which joint should be strengthened to improve gait pattern.

[Purpose] The aim of this study was to clarify the relationships among muscle fiber conduction velocity, time-force characteristics of muscle force production, and voluntary movement in patients with hemiplegia. [Subjects and Methods] The participants in the present study were 13 patients with hemiplegia. Muscle fiber conduction velocity, deep temperature of muscles and muscle thickness were measured for the tibialis anterior, and a time force curve was obtained from dorsiflexion of the ankle and lower thigh girth (maximum, minimum) for both sides. The maximum torque rate of change and maximum torque were calculated from the force-time curve. In addition, Brunnstrom Recovery Stage was used to evaluate the function of the hemiplegic side. [Results] In all the measurement items, significant differences were observed between the hemiplegic side and the healthy side. The maximum torque rate of change and Brunnstrom Recovery Stage showed a high degree of correlation. The muscle fiber conduction velocity and maximum torque rate of change or maximum torque showed a medium degree of correlation. However, muscle fiber conduction velocity was not significantly correlated with Brunnstrom Recovery Stage. [Conclusion] Brunnstrom Recovery Stage was good as a determination factor for the maximum torque rate of change. In addition, in patients with hemiplegia, it became clear that relationship is between muscle fiber conduction velocity and time-force characteristics of muscle force production as in healthy persons.

[Purpose] This study investigates how a task-oriented training and high-variability practice program can affect the gross motor performance and activities of daily living for children with spastic diplegia and provides an effective and reliable clinical database for future improvement of motor performances skills. [Subjects and Methods] This study randomly assigned seven children with spastic diplegia to each intervention group including that of a control group, task-oriented training group, and a high-variability practice group. The control group only received neurodevelopmental treatment for 40 minutes, while the other two intervention groups additionally implemented a task-oriented training and high-variability practice program for 8 weeks (twice a week, 60 min per session). To compare intra and inter-relationships of the three intervention groups, this study measured gross motor performance measure (GMPM) and functional independence measure for children (WeeFIM) before and after 8 weeks of training. [Results] There were statistically significant differences in the amount of change before and after the training among the three intervention groups for the gross motor performance measure and functional independence measure. [Conclusion] Applying high-variability practice in a task-oriented training course may be considered an efficient intervention method to improve motor performance skills that can tune to movement necessary for daily livelihood through motor experience and learning of new skills as well as change of tasks learned in a complex environment or similar situations to high-variability practice.

[Purpose] This study investigated the association between proprioception, including joint position sense and kinetic sense, and handwriting legibility in healthy children. [Subjects and Methods] Assessment of joint position sense, kinetic sense, and handwriting legibility was conducted for 19 healthy children. Joint position sense was assessed by asking the children to flex their right elbow between 30° to 110° while blindfolded. The range of elbow movement was analyzed with Compact Measuring System 10 for 3D motion Analysis. Kinetic sense was assessed using the Sensory Integration and Praxis Test. The children were directed to write 30 words from the Korean alphabet, and the legibility of their handwriting was scored for form, alignment, space, size, and shape. To analyze the data, descriptive statistics and Spearman correlation analysis were conducted using IBM SPSS Statistics 20.0. [Results] There was significant negative correlation between handwriting legibility and Kinetic sense. A significant correlation between handwriting legibility and Joint position sense was not found. [Conclusion] This study showed that a higher Kinetic sense was associated with better legibility of handwriting. Further work is needed to determine the association of handwriting legibility and speed with Joint position sense of the elbow, wrist, and fingers.

[Purpose] The present study aimed to understand characteristics of sensory processing in patients who have experienced a stroke using the previously established, self-diagnostic Adolescent/Adult Sensory Profile (AASP). [Subjects and Methods] Data from 180 total Korean patients who had been diagnosed as having experienced a stroke were collected and analyzed between May and August of 2015. [Results] Average scores for each sensory processing domain were as follows: low registration (32.1), sensation seeking (34.3), sensory sensitivity (36.7), and sensation avoiding (34.0). Study participants exhibited similar scores to healthy controls (data obtained from previous studies) with the following frequencies: low registration (65%), sensation seeking (77.2%), sensory sensitivity (65%), and sensation avoiding (62.2%). Significant differences were observed between control data and scores obtained for study participants in all domains except that of sensory sensitivity. [Conclusion] The results of the present study indicate that therapeutic intervention following the experience of a stroke should account for individual differences in sensory processing abilities to provide the environment most conducive to the patient’s overall cognitive and physical improvement.

[Purpose] This study aimed to examine the effects of interventions on constipation and to provide basic data for physical therapy in internal medicine. [Subjects and Methods] The colon transit times of 30 subjects were measured and after the interventions. Fifteen subjects were assigned to a Maitland orthopedic manual therapy group, and 15 subjects were assigned to a dietary fiber group. [Results] The analysis of changes in colon transit time showed statistically significant differences in left colon transit time, rectosigmoid colon transit time, and total colon transit time for the Maitland orthopedic manual therapy group and statistically significant differences in rectosigmoid colon transit time and total colon transit time for the dietary fiber group. An analysis of group differences in the effects of Maitland orthopedic manual therapy and dietary fiber showed that the Maitland orthopedic manual therapy group achieved statistically significantly larger declines in rectosigmoid colon transit time and total colon transit time compared with the dietary fiber group. [Conclusion] This study confirmed that Maitland orthopedic manual therapy can be an effective treatment method for internal conditions such as functional constipation by almost normalizing the colon transit time, not only by improving the symptoms of constipation but also by facilitating intestinal movements.

[Purpose] This study was conducted to investigate the effect of Wiihabilitation on the ankle dorsiflexion/plantar flexion strength ratio in adults. [Subjects and Methods] Thirty-two healthy male volunteers were randomly assigned to two equal groups (experimental and control). Participants in the experimental group received a Wiihabilitation training program for six weeks. Data were collected using a Biodex system 3 Isokinetic dynamometer. Peak torques of the dorsiflexors and plantar flexors were measured at an angular velocity of 60°/sec which in turn were used to derive the ankle dorsiflexion/plantar flexion strength ratio. [Results] The mean values of the ankle dorsiflexion/plantar flexion strength ratio decreased significantly between before and after the training in the experimental group, meanwhile there was no significant difference between before and after the training period in the control group . [Conclusion] Wiihabilitation has an impact on the ankle dorsiflexion/plantar flexion strength ratio, so it can be considered an effective training tool in terms of the ankle strength ratio. Thus, it could be recommended for both prevention and rehabilitation of ankle instability patients.

[Purpose] The aim of the present study was to understand the coping strategies used during physical therapy clinical practice. [Subjects and Methods] Sixty-eight of 77 physical therapy students (88.3%) responded to questionnaires, including a tri-axial coping scale and a scale of stress reactions after clinical practice (median age=22 years; 45 were male, 23 were female; 37 third-year students, 31 fourth-year students). The scores of males and females were compared via descriptive statistics. In addition, stepwise logistic regression analysis was performed. Dummy variables were created based on the median scores of stress reactions (0=slight reactions; 1=severe reactions), and were used as the dependent variables. [Results] The stress reaction scores of female (median score=7 points) were significantly higher than those of male students (5 points). The following significant logistic regression equation was obtained: log (p / (1−p))=1.78 + 1.96 [gender (0=male; 1=female)] + 0.30 (buck passing strategy). The odds ratios for gender and buck passing were 7.12 and 1.34, respectively. [Conclusion] Clinical practice educators should be aware that female students and those that use buck passing are more likely to suffer from severe stress reactions during physical therapy clinical practice.

[Purpose] The number of bedridden patients requiring nursing care in Japan has increased sharply in recent years because of its aging population and advances in medical care and has become a major social issue. Because bedridden patients are susceptible to nursing and healthcare-associated pneumonia, it is very important to improve their immunocompetence. Therefore, the effect of exercise therapy on stimulation of cytokine secretion in the saliva of bedridden patients was investigated. [Subjects and Methods] The subjects of this study were bedridden patients admitted to nursing care facilities. They were instructed to perform active assistive movement in the supine and sitting positions, with vital signs used as an index of the exercise load. Thirty-five patients fulfilled the inclusion criteria, which included cerebrovascular disease as the main cause of being bedridden and at least 6 months since onset. Interleukins were measured by enzyme-linked immunosorbent assay as immune mediators. [Results] Vital signs improved significantly after therapeutic exercise intervention, and the IL-6, IL-8, IL-15, and IL-17 levels also increased significantly after the intervention. [Conclusion] The results demonstrated that measurement of saliva samples may offer a safe minimally invasive method of measuring immune response in bedridden patients. This study suggests that exercise therapy may hold promise as an effective means of improving immunity in bedridden patients and may contribute to preventing aspiration pneumonia and promoting spontaneous recovery.

[Purpose] The present study compared assessments utilized to evaluate judgment errors in the elderly. [Subjects and Methods] A total of 94 community-dwelling elderly participants in an examination of physical fitness for health promotion and health guidance in a rural area in Japan were included. Spatially and temporally predictive tasks were used to evaluate judgment errors. Distances measured on the Functional Reach and upward reaching tests were used to assess spatial prediction, and times measured on the Timed Up and Go test and Standardized Walking Obstacle Course were used to assess temporal prediction. Differences between the self-predicted values and actual results were deemed judgment errors. [Results] Significant differences were observed between self-predicted abilities and the patients’ performances. Participants underestimated their abilities in spatially predictive tasks and overestimated them in temporally predictive tasks. On comparing the four tasks, there were significant differences in judgment error ratios between them. Statistical analysis indicated a significant difference in the judgment error ratio for the Standardized Walking Obstacle Course correlated with a history of falls. [Conclusion] Judgment errors were identified using both spatially and temporally predictive tasks. A temporally predictive task like the Standardized Walking Obstacle Course might better evaluate judgment errors in the elderly.

[Purpose] The purpose of this study was to identify factors related to physical characteristics and lifestyle that affect pulmonary function. [Subjects and Methods] Ninety seven healthy male workers were recruited for this study, and basic information and details about lifestyle were collected. Body composition analyzer and visceral fat measuring device were conducted as measurements. Pulmonary function was measured using spirometer. A multiple stepwise linear regression analysis was performed with pulmonary function as the dependent variable. Variables with a significant association with pulmonary function on univariate analysis were imputed as independent variables. [Results] Height, fat free mass, upper extremity muscle mass, lower extremity muscle mass, and trunk muscle mass had significant positive correlations with FEV1 and FVC. Age, percentage of body fat, and visceral fat area were negatively correlated with FEV1 and FVC. Regarding the association between pulmonary function and lifestyle, a significant difference was found between the smoking index and the presence or absence of metabolic syndrome risk factors and both FEV1 and FVC. The multiple stepwise linear regression analysis with FEV1 as the dependent variable, adjusted for age and height, revealed that visceral fat area and fat free mass were significantly associated with FEV1. A similar analysis, FVC as the dependent variable identified visceral fat area. [Conclusion] FEV1 was independently associated with visceral fat area and fat free mass. FVC was independently associated with visceral fat area. These results may be valuable in preventing the decrease in respiratory function and, hence, in further preventing the onset of COPD.

[Purpose] The purpose of this research was to determine the effect of combined exercise with slings and a Flexi-Bar on muscle activity and pain in rotator cuff repair patients. [Subjects and Methods] This research evaluated 20 rotator cuff repair patients divided randomly into groups of 10 as the control group and the experimental group. The experimental group performed combined exercise with slings and a Flexi-Bar. Both the experimental and control groups were treated with a transcutaneous electrical nerve stimulator and continuous passive motion. Muscle activity was measured with surface electromyography. Pain was measured with the visual analogue scale. The paired t-test was used to compare groups before and after the experiment. The independent t-test was used to assess the differences in the degree of change between the two groups before and after the experiment. [Results] Subjects of both the experimental group and control group showed significant differences in muscle activity and pain. However, as compared with the control group, there was significant differences in the muscle activity and pain in the experimental group. [Conclusion] These results indicate that combined exercise with slings and a Flexi-Bar is effective in improving muscle activity and decreasing pain in rotator cuff repair patients.

[Purpose] The purpose of the present study was to examine the effects of neurofeedback training on postural changes in the cervical spine and changes in the range of motion of the neck and in the Neck Disability Index in adults with forward head posture. [Subjects and Methods] The subjects of the study were 40 college students with forward head posture, randomly divided into a neurofeedback training group (NFTG, n=20) and a control group (CG, n=20). The neurofeedback training group received six sessions of pottery and archery games, each for two minutes, three times per week for four weeks, using the neurofeedback system. [Results] There were no significant effects within and between groups in terms of the absolute rotation angle, anterior weight bearing, and range of extension and flexion by x-ray imaging. There were significant effects in the neurofeedback training group pre- intervention and post-intervention in Neck Disability Index. There were significant effects between groups in Neck Disability Index. [Conclusion] It is thought that neurofeedback training, a training approach to self-regulate brain waves, enhances concentration and is therefore an effective intervention method to improve neck pain and daily activities.

[Purpose] This study aimed to investigate the effects of exercise on the autonomic nervous system of breast cancer survivors by measuring heart rate variability during an 8-week circulation exercise program. [Subjects and Methods] This intervention study included 22 volunteer female participants, younger than 65 years, who were selected from patients who had been diagnosed with carcinoma in situ and primary invasive breast cancer, stage I-III, in accordance with the American Joint Committee on Cancer (2009) and had undergone breast surgery. [Results] Despite the statistically significant differences in the low-frequency range (log), the high-frequency range (log), the standard deviation of the N-N interval, and the root mean square of differences values, which are heart rate variability indicators after exercise, between the two groups, no statistically significant difference was found in the low-frequency range/the high-frequency range values between the two groups. [Conclusion] The improvement in heart rate variability during the 8-week circulation exercise program confirms the increase in the activity of the autonomic nervous system of breast cancer patients after surgery.

[Purpose] The aims of the present study were to investigate the most suitable location for vibroarthrography measurements of the knee joint to distinguish a healthy knee from knee osteoarthritis using Wavelet transform analysis. [Subjects and Methods] Participants were 16 healthy females and 17 females with severe knee osteoarthritis. Vibroarthrography signals were measured on the medial and lateral epicondyles, mid-patella, and tibia using stethoscopes with a microphone while subjects stood up from a seated position. Frequency and knee flexion angles at the peak wavelet coefficient were obtained. [Results] Peak wavelet coefficients at the lateral condyle and tibia were significantly higher in patients with knee osteoarthritis than in the control group. Knee joint angles at the peak wavelet coefficient were smaller (more extension) in the osteoarthritis group compared to the control group. The area under the receiver operating characteristic curve on tibia assessment with the frequency and knee flexion angles was higher than at the other measurement locations (both area under the curve: 0.86). [Conclusion] The tibia is the most suitable location for classifying knee osteoarthritis based on vibroarthrography signals.

[Purpose] This study aimed to classify the fear that occurs during the process of a squat-like movement by persons with visual impairment. [Subjects and Methods] Fifteen persons with a visual impairment, 45 years and older, who were independent in daily living were recruited for the study. The study utilized a field experiment design. The setting was the Kusatsumachi Welfare Center, and the study period was from March through August 2015. Outcome measures included the presence or absence of fear during attempt of a squat-like movement on a force plate. Metrics included the ratio of low and high frequency components of heart rate variability spectra (cm²/Hz) based on resting rate intervals (ActiGraph wGT3X-BT, USA). Autonomic hyperactivity was defined as the occurrence of objective fear with LF/HF ratio of over 2.0. Statistics included Fischer’s exact test. [Results] Four fear types included the combination of danger and objective fear factors. The frequencies of occurrence of clinically categorized subjective fear across the four fear types were two (danger, fear), seven (no danger, fear), six (danger, no fear), and zero (no danger, no fear) persons. [Conclusion] This procedure of classifying fear might be feasible during evaluation of a squat-like movement by persons with a visual impairment.

[Purpose] To evaluate the quality of life of critical illness survivors in a developing country over the time after hospital discharge and to assess the influence of clinical variables on quality of life. [Subjects and Methods] A prospective longitudinal study was conducted in a large, tertiary, public hospital in Sao Paulo, Brazil. We included patients ≥18 years old, hospitalized in the intensive care unit with ≥24 hours of invasive mechanical ventilation. Quality of life was assessed using the Medical Outcomes Study 36-Item Short Form Health Survey, which was applied by telephone interview at the first, third and sixth months after hospital discharge. [Results] 75 patients were included in the study. Quality of life improved progressively after hospital discharge; role-physical was the most compromised domain. The physical component was influenced by the age. Quality of life was not influenced by Apache II categorization, length of invasive mechanical ventilation, intensive care unit stay or hospital stay. [Conclusion] Survivors of critical illness in a developing country present poor quality of life, which improves over time. Age influenced the physical component of quality of life.

[Purpose] The purpose of the study was to investigate the effects of exercise on the recovery of spinal cord nerve cells damaged due to pain signals which are a major symptom of osteoarthritis. [Subjects and Methods] Adult male Sprague-Dawley rats (n=40) were used and induction of osteoarthritis by monosodium iodoacetate. Injected rats were randomly divided into 4 groups: Sham control group without MIA injection (SG), control group with injected MIA (CG), OA without exercise (NEG), OA with exercise (EG). Sham control group was injected normal cell line instead of MIA. The exercise group was submitted to 4-week training program on a treadmill for 5 days/week, 30 min/day, 16 m/min velocity, then spinal cord were removed and measured the GAP-43 expression by immunohistochemistry analysis. [Results] In this study, a results of measuring the expression of GAP-43. GAP-43 was observed in all groups, showed that the significant difference in each group. [Conclusion] It could be seen that exercise increased the GAP-43 expression in the spinal cord to promote the recovery of spinal cord nerve cells damaged due to chronic osteoarthritis.

[Purpose] The purpose of this study was to find the influential factors of maximal-effort expiratory capacity of elderly women. [Subjects and Methods] The subjects of this study were 83 healthy elderly women. The study’s methods and purpose were explained and these women agreed to participate. The maximal-effort expiratory capacity was measured using spirometry (Pony FX, COSMED Inc., Italy). We measured forced vital capacity, forced expiratory volume in 1 second, forced expiratory volume in 1 second/forced vital capacity, maximal expiratory flow 75%, maximal expiratory flow 50%, and maximal expiratory flow 25%. [Results] Regarding forced vital capacity and forced expiratory volume in 1 second, it was found that height and age were influential factors. Regarding forced expiratory volume in 1 second/forced vital capacity %, maximal expiratory flow 75%, maximal expiratory flow 50%, and maximal expiratory flow 25%, it was found that only age was an influential factor. [Conclusion] This study demonstrated that the most influential factors of maximal-effort expiratory capacity of elderly women were age, and the second influential factor was height. We noticed that weight was the least influential factor among them.

[Purpose] The present study aimed to examine the correlation between rounded shoulder posture, neck disability indices and the degree of forward head posture. [Subjects and Methods] Subjects aged 19–24 years were selected for this study, and the craniovertebral angle was used to measure the degree of forward head posture in the standing and seated positions. Vernier calipers were used to measure rounded shoulder posture in the supine position, and neck pain and functional disability were assessed using neck disability indices. [Results] Angle and neck disability indices in both standing and sitting posture positions exhibited a significant inverse relationship. However, no significant correlation was detected between the craniovertebral angle and rounded shoulder posture for the standing and sitting posture positions. [Conclusion] In conclusion, it was demonstrated in the present study that, depending on the degree of forward head posture, changes were detected in the neck disability indices. However, even an increase in the forward head tilt angle did not lead to rounded shoulder posture. Therefore, maintaining proper posture may prevent postural pain syndrome, functional disability, and postural deformity.

[Purpose] The present study aimed to separately compare systolic blood pressure and diastolic blood pressure with health and fitness-related variables among Asian obese and normal weight middle-aged women. [Subjects and Methods] The study included 1,201 women aged 30–59 years. The participants were classified into obese and normal weight groups. The blood pressure and health and fitness-related variables of all participants were assessed. [Results] Significant interaction effects were observed for most blood pressure and health and fitness-related variables between the groups. However, significant interaction effects were not observed for standard weight, basal metabolic rate, and heart rate. Blood pressure showed significant positive correlations with weight, body fat, fat weight, core fat, body mass index, and basal metabolic rate in both groups. Systolic blood pressure was significantly correlated with muscular endurance, power, and agility in the obese group and with VO2max and flexibility in the normal weight group. Diastolic blood pressure was significantly correlated with muscular endurance and power in the obese group and with VO2max in the normal weight group. [Conclusion] The relationships between systolic blood pressure and heart rate, muscle endurance, power, and agility are stronger than the relationships between diastolic blood pressure and these variables.
