This study collected the questionnaire from the new participants who are middle-aged and elderly people in project of incentives led by local governments. This study focuses on the exercise group and non-exercise groups proportion of pefered incentives and the correlation of perfered incentives in these two groups. This study analyzed 9,590 middle-aged and elderly people who participated in a health promotion project with incentives and answered a questionnaire during the period of participation. The incentives were included 4 types: (1.) regional gift cards; (2.) national gift cards; (3.) rewards points that could be used at department stores and convenience stores nationwide, and (4.) donations. The result shows that both non-exercise and exercise groups preferred financial incentives over non-financial incentives. By type of monetary incentive, non-exercise group were more likely to prefer national gift certificates 1.39 times (OR: 1.39, 95%CI: 1.03-1.89); significantly more likely to prefer rewards point 1.44 times (OR: 1.44, 95%CI: 1.07-1.95) over non-monetary incentives compared to exercise group. Among the middle-aged and elderly people who participated in a health promotion program with incentives, the majority of two groups showed the preference that financial incentives over nonfinancial incentives. Comparing monetary incentives, both groups preferred local gift certificates than national gift certificates and rewards point.

This study aimed to evaluate the effects of ingesting yogurt fermented with Lactobacillus delbrueckii subsp. bulgaricus (OLL1073R-1) on the immune function of healthy university men track and field athletes. Study design Randomized, double-blind, placebo-controlled, parallel-group study. A total of 37 track and field athletes aged ≥18 years were randomly assigned into two groups. For 2 weeks, two bottles of yogurt fermented with OLL1073R-1 and Streptococcus thermophilus OLS3059 or placebo sour milk were ingested daily to the participants. During the intake period, a 1-week training camp was held and participants were subjected to strenuous exercise. Natural killer (NK) cell activity, which is the primary endpoint, was significantly lower in the placebo group after ingestion than that at baseline; however, it remained unchanged during the pre-exercise level of the yogurt group. The two-way repeated measures analysis of variance showed an interaction effect in the NK cell activity change (P=0.018) and a significant difference between the groups after the 2-week ingestion (P=0.015). Among the secondary endpoints, cytokines and chemokines levels involved in activating innate immunity maintained or enhanced only in the yogurt group. ALT, LDH, and CK significantly elevated only in the placebo group. Furthermore, amino acid levels were significantly lower in the placebo group after ingestion than that at baseline; however, it remained unchanged during the pre-exercise level in the yogurt group. Consuming yogurt fermented with OLL1073R-1 prevents the decline in immune function associated with strenuous exercise. Additionally, the yogurt may contribute to stable physical condition.

Recently, poor posture (hyperkyphosis) has become a problem among children. This study investigated the effectiveness of an intervention (a spine mat) by measuring spinal alignment before and after the intervention in elementary school students. The study included 83 elementary school students. For the intervention, each participant was placed in a supine position on a bed and a spine mat was inserted ensuring that it adhered to the thoracic spine. The primary outcome variables included the thoracic kyphosis angle (TKA), upper thoracic angle, lower thoracic angle, lumbar lordosis angle (LLA), and sacral anteversion angle (SAA) measured in the standing and sitting positions using Spinal Mouse® before and after the intervention. Based on this evaluation, we assigned the participants to two groups: hyperkyphosis (n=25) and non-hyperkyphosis (n=58). Significant differences were observed between the pre-test and post-test TKA in the hyperkyphosis group in the standing position (pre-test: 45.3±4.5° and post-test: 40.8±9.0°, P<0.05). In the non-hyperkyphosis group, significant differences were observed between the pre-test and post-test LLA and SAA in the standing position. However, no significant difference was observed between the pre-test and post-test spinal alignment in the sitting position in both groups. The results of this study indicated that using a spine mat in elementary school children resulted in decreased TKA in the standing position only in the hyperkyphosis group, which exhibited a TKA of 40° or more after the intervention.

Women who suffer out-of-hospital cardiac arrest receive cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) less frequently than that of men. Understanding the public perception on the necessity of the occurrence of life-saving disparities for fair intervention application to individuals with injuries and sickness is needed. The participants were undergraduate students of the university. Anxiety and irritability towards bystander CPR and AED operations were investigated. The participants of the analysis were 368 individuals (153 men and 215 women), of which 80.4% of men and 95.8% of women had anxiety about life-saving procedures. Regarding AED operation, 90 (58.8%) men and 74 (34.4%) women hesitated on removing clothing from a woman with injury or sickness. The reasons on women with injury and illness were less likely to be suitable with AEDs involved anxiety about life-saving procedures, litigation issues, and posting and spreading on social networking sites (SNS). Particularly, if men intervened with women with wounds, the main limitations were the risk of the act developing into a lawsuit and gaze of others, namely SNS. Bystander anxiety towards life-saving procedures was found to be strongly expressed by women. It also became evident that early recognition of cardiac arrest was not performed for patients with injuries 20–30% of the time. Training specifically for women with wounds and sickness may reduce sex differences in bystander CPR and AED application.

Present study aimed to examine the effects of high-intensity intermittent training on metabolic or circulatory parameters and exercise time during 30s-lasting exhaustive exercise. Six healthy males (22 ± 1yrs) had an intermittent training four days a week for four weeks. The intermittent training consisted of 8 or more sets of 20s exercise bout at an intensity of 170%VO₂ max separated by 10-s recovery. Before and after training period, VO₂ max and maximal accumulated O₂ deficit (MAOD) were determined as indices of metabolic capacity. During 30s-lasting exhaustive exercise, VO₂, O₂ deficit, and circulatory parameters, such as heart rate, stroke volume, and cardiac output, were also determined every 10s. After the training, VO₂ max and MAOD were significantly increased. During 30s-lasting exhaustive exercise, exercise time, stroke volume, and cardiac output were also significantly enhanced. However, no significant differences were observed in VO₂ and O₂ deficit every 10s during 30s-lasting exhaustive exercise. Therefore, these findings suggest that high-intensity intermittent training enhances exercise time during 30s-lasting exhaustive exercise and that the improvement of exercise performance is closely related to an increase in anaerobic capacity.
