This study compares the effects of a 12-week combined strength, power, and neuromotor exercise training on middle-aged men. Twenty-two healthy individuals (aged 40-64 years) were divided into younger middle-aged subjects (YM: 41.5 ± 1.5 year, n = 8) and older middle-aged subjects (OM: 53.1 ± 5.6 year, n = 14). The training program consisted of a 60-min supervised group exercise session once every two weeks at their work place and additional home exercise. After the 12 weeks of training, vertical jump height and power increased by 18.0 and 7.2% (P < 0.05) in YM and 22.6 and 11.5% (P < 0.05) in OM. The rebound jump index decreased by 14.3% (P < 0.05) in YM, but increased by 7.6% (P < 0.05) in OM. There were no differences in either group in the mean and maximum cycling power outputs. The chair-stand performance increased by 21.5% (P < 0.05) in YM and 13.7% (P < 0.05) in OM. There were no significant changes in the 2-min step in either group after the training. The only significant difference after training was in the rebound jump index in YM compared with OM. This study indicates that the combined training program may have limited effects on lower extremity muscle function in older middle-aged men.

　The evaluation about the stress of the human has many subjective evaluations by the questionnaire. There is no good evidence suggest that the objective stress evaluation using the biological sample. 　Therefore, in this study, we measured spot urinary cortisol concentrations (Urinary free cortisol/Creatinine: UFC/Cr) on the protector of the infants. 　We studied it for the purpose of the association between UFC/Cr concentrations and subjective evaluation level of the questionnaire about the stress. Furthermore, we considered whether UFC/Cr concentrations could become the objective stress evaluation biomarker. 　The subjects are 99 infants and the 102 parents. The study conducted after the approval of the university of Shizuoka ethical review board after informed consent of subjects. The investigation items are anthropometric data, questionnaire survey about the stress, UFC/Cr. We divided into two groups UFC/Cr of parents (less than 75%ile group, more than 75%ile group) and analyzed it about each survey items. 　An association between subjective stress evaluation level and UFC/Cr was suggested in the parents. In the adults, it was suggested that spot urinary UFC/Cr concentrations became the stress biomarker.

　This study investigated the learning experience of school nurses regarding same-sex sexual orientation (“the learning experience” hereafter) and its interaction with their awareness of and response to student consultations. We analyzed the learning experience of 500 school nurses out of the 932 working at junior and senior high schools and special support education schools in Prefecture A. Many of the university graduates in their 20s acquired the learning experience at educational institutions (7.8%), while many of the junior college graduates in their 40s acquired it after working as school nurses(51.6%), and 10.6% both at educational institutions and after starting work. Those with 1-9 years of work experience mostly acquired the learning experience at educational institutions (92.3%), while those with 20-29 years of work acquired it after starting work (33.7%). Those trained in it were more willing to respond to student consultations on same-sex sexual orientation and tended to receive more such requests. However, the learning experience was not directly connected to the sensitivity about students’ individuality for establishing ego identity, providing diverse educational materials in school infirmaries to deepen understanding, and offering counseling. School nurses are required to endeavor to accept the existence of the students with same-sex sexual orientation.

　We aimed to examine the coaching points for jumping movements by performing kinematic analysis of 3-year-old girl children with excellent or inferior jumping ability. To assess jumping ability, we tested standing long jump in 113 children, and then selected 12 children (excellent and inferior jumping ability). We filmed the standing long jumps with high-speed video cameras, and then performed three-dimensional analysis of the joint angle and the angular velocity of the upper and lower limbs by using the DLT method. Our results suggested that a jump-preparatory motion that involved bending the lower limbs to a great degree was not effective. While coaching for children with inferior jumping ability, it might be effective to make the children rotate the thigh around the hip joint and move their arms forward. It seemed that a quick return movement of arms in the swing during the taking-off phase was effective in achieving substantial hip-joint bending power in the first half of the take-off phase.

　In this study, we examined the incidence of sports injuries through a support model of athletic training between 2008 season and 2010 season. As a result, the following findings were obtained. 1. There were 134 injuries in 2008 season and 83 injuries in 2010 season. The significant difference was observed in the incidence of 2008 and 2010 (p<0.01). Moreover, while the incidence decreased in football (p<0.01), kendo (p<0.05), but the incidence in track and field increased (p<0.05). 2. The injury pattern (acute or overuse) was no significant difference, but the incidence of acute injury had been decreased in football. 3. There was a significant difference in injury part of body (p<0.05), and upper extremity and lower extremity had been decreased. Moreover, the incidence of trunk/back had been increased. 4. There was a significant difference in injury situation (p<0.05), and the incidence in the match and the training had been decreased. 5. The severity was no significant difference, but the severity of injury had been reduced in each grade. 6. There was a significant difference in incidence of each grade (p<0.01), and the incidence had decreased through the experience of a support model of athletic training.

　This study was aimed at interpreting the meaning of both objective and subjective evaluations of the patient's stress with skin itch disease. The subjects were 87 atopic dermatitis patients (AD) and 102 chronic-urticaria (CU) patients. Skindex16 was used for the subjective evaluation. Short-time autonomic-nerves measurement was carried out, and the LF/HF was adopted as an index for the objective evaluation. The results showed the following: 1) although the scores of symptom, emotion and function of Skindex16, and the disease duration were mutually related, the LF/HF was unrelated. 2) Although AD patients had higher scores of Skindex16 than CU, the median value of LF/HF (1.9) in AD patients did not show a significant difference from that of LF/HF (2.2) in CU patients. 3) It was observed that one of risk factors of high LF/HF (6.5) occurred when the comprehensive score of Skindex16 was low, even if frequency was low. From the results, it became clear that there is a gap between the evaluation of subjectivity and objectivity, conversely, less complaint may become one of the risk factors of high LF/HF, and as for LF/HF, we judged that around 2.0, as a standard value, has validity. It was concluded that the short-time measurement of autonomic nerves is meaningful when used together with questionnaire investigation to carry out an evaluation of patient's stress factor in clinical dermatology.

　No reports were published in regards to analyses on the changes with age in the physical strength and correlation among the physical strength of members of the South Korean navy over several decades after reaching adulthood. Analysis of physical strength data for Korean sailors is important from the perspective of national defense in Korea. In this study we applied a least squares approximation polynomial to the age distance values for push-ups, sit-ups, and 3,000 m run in members of the Korean navy aged 19 to 50 years to evaluate the changes in their physical strength with age, and computed the correlation coefficients among the physical strength. The subjects were Korean navy personnel in the vicinity of Busan, South Korea, and the tests were conducted in July and August, 2010. Measurement data for 2104 male sailors aged 19-50 years and people associated with the military were obtained. It was found that secondary approximation polynomials were valid for push-ups and sit-ups, and that a primary approximation polynomial was valid for the 3,000 m run. Moreover, Higher trend of the simple and multiple correlation among physical strength was found according to change with age. An evaluation chart was then constructed of the trends in changes with age obtained with least squares approximation polynomials. Using this chart, it is thought that information can be obtained on the kinds of efforts that can be made to maintain or promote physical ability, which is the most basic quality for the Korean navy, and measures for those efforts.
