Objectives: The purposes of this study was to describe workers' perceived values and the affecting factors (pros and cons) of the experience education for occupational safety and health and to suggest the strategies and future directions to improve the experience educational quality. Methods: A total of 8 male workers taking the safety and health education of the 7 safety experience education centers involved in this study (5 centers managed by Korea Occupational Safety and Health Agency (KOSHA), 2 centers of large commercial companies). This study used Photovoice, a qualitative method, as the study method. We conducted the photovoice-based in-depth interview with the SHOWeD questions and strategy and used the taxonomical analysis. Results: The study participants' perceived values of experience education were strengthening self-efficacy of the safety and health practices, providing practically useful information, and enjoying refreshing experiences different from daily jobs. Positive affecting factors of the experience education (pros) were providing the educational environments and opportunities of direct experiences, teaching practical safety and health contents for the participants, and the trainer's instruction competencies. Negative affecting factors of the experience education (cons) were learner's negative or standing postures during trainer's lecturing, insufficient exercise conditions and facilities for education, and difficult and theory-oriented lecture far from the practical jobs in reality. Conclusions: Major values of exercise education were direct experiences, useful contents and interesting opportunities from the education participants' perspectives. To improve the exercise education quality, overall educational environments such as convenience facilities as well as exercise facilities should be modified altogether. This study partially and conveniently used the photovoice method as the study limitation.

The purpose of this study was to identify the factors influencing the Exercise Performance of elderly patients with diabetes. The subjects were 153 elderly patients with diabetes who were selected from the public health center in Gwang ju. The data collected was analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation and stepwise multiple regression. This study found that approximately 52.9% of the subjects were exercising regularly. Exercise performance was significantly different according to education level, family income by month, and level of diabetes education. Significant factors influencing exercise performance were exercise self-efficacy, exercise social support and exercise benefits. The most powerful predictor of exercise performance was exercise self-efficacy(34.2%). This study suggests that nurses should emphasize exercise social support. and exercise benefits as well as reinforce exercise self-efficacy to improve exercise performance of the elderly patients with diabetes.

[Purpose] The purpose of this study was to identify the relationships between muscle mass, muscle strength, and physical and cognitive functions and to examine the effects of resistive Theraband® exercise on sarcopenia-associated variables in the older population. [Methods] A total of 28 elderly women (age: 69.90 ± 0.8 years) participated in this study, 15 of whom underwent elastic band exercise for 1 hour per day, twice per week for 8 weeks. The correlation analysis was conducted to identify the associations between body composition, skeletal muscle mass indices, grip strength, and physical and cognitive functions. All variables were assessed at baseline and post-exercise. [Results] Skeletal muscle mass was significantly associated with grip strength and physical function. Gait speed was positively correlated with grip strength and physical function, but not with cognitive function. Theraband® exercise significantly improved gait speed and physical function. [Conclusion] The present data suggest that skeletal muscle mass is highly correlated with grip strength and physical function. Eight weeks of resistive Theraband® exercise favorably affects sarcopenia by improving gait speed and mobility of elderly women.

We investigated the effect of moderate- and high-intensity resistance training on hippocampal neurotrophic factors and peripheral CCL11 levels in high-fat diet (HFD)-induced obese mice. C57/black male mice received a 4 weeks diet of normal (control, CON; n = 9) or a high-fat diet (HF; n = 27) to induce obesity. Thereafter, the HF group was subdivided equally into the HF, HF + moderate-intensity exercise (HFME), and HF + high-intensity exercise (HFHE) groups (n = 9, respectively), and mice were subjected to ladder-climbing exercise for 8 weeks. The hippocampal brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) levels were significantly lower in the HF group than in the CON group (p < 0.05). In addition, in the HFME and HFHE groups were significantly higher than in the HF group (p < 0.05). The peripheral CCL11 levels were significantly higher in the HF group than in the CON group (p < 0.05). In addition, in the HFME and HFHE groups were significantly lower than in the HF group (p < 0.05). However, there was no significant difference according to the exercise intensity among the groups. Collectively, these results suggest that obesity can induce down-regulation of neurotrophic factors and inhibition of neurogenesis. In contrast, regardless of exercise intensity, resistance training may have a positive effect on improving brain function by inducing increased expression of neurotrophic factors.

By improving body composition, such as fat, lean body mass and total body weight, an exercise program can be an effective treatment of obesity. The effects of exercise on obesity have been confirmed via various approaches such as type, intensity, duration, frequency, and combination with diet. Combined exercise and diet is the most efficient strategy for weight loss, and exercise alone could improve metabolism irrespective of weight loss. In addition, physical activity, including exercise, is emphasized to avoid a 'yo-yo' phenomenon. Exercise increases lipolysis stimulated by such factors as catecholamine, growth hormone (GH), and hormone sensitive lipase (HSL). Moreover, changes in insulin and cortisol through exercise affect adipose tissue, which is known as not only an energy storage locale, but also as an endocrine organ. Adipocytokines secreted by adipose tissue respond to signals that modulate metabolism and inflammation. Exercise has generally shown positive effects on adipocytokines, and these effects increase in conjunction with a hypocaloric diet. However, a long duration and a high intensity of exercise could induce an inflammatory response. This review summarizes the effects of exercise on obesity treatment, which contributes to the exercise and nutritional fields, particularly of community nutritionists.

Exercise-mediated physical treatment has attracted much recent interest. In particular, swimming is a representative exercise treatment method recommended for patients experiencing muscular and cardiovascular diseases. The present study sought to design a swimming-based exercise treatment management system. A survey questionnaire was completed by participants to assess the prevalence of muscular and cardiovascular diseases among adult males and females participating in swimming programs at sport centers in metropolitan regions of country. Using the Fuzzy Analytic Hierarchy Process (AHP) technique, weighted values of indices were determined, to maximize participant clarity. A patient management system model was devised using information technology. The favorable results are evidence of the validity of this approach. Additionally, the swimming-based exercise management system can be supplemented together with analyses of weighted values considering connectivity between established indices.

BACKGROUND/OBJECTIVES: To investigate the effect and regulatory mechanism of resveratrol supplementation on the mitochondrial energy metabolism of rats with exercise-induced fatigue. MATERIALS/METHODS: Forty-eight Sprague-Dawley male rats were divided randomly into a blank control group (C), resveratrol group (R), exercise group (E), and exercise and resveratrol group (ER), with 12 rats in each group. Group ER and group E performed 6-wk swimming training with 5% wt-bearing, 60 min each time, 6 days a wk. Group ER was given resveratrol 50 mg/kg by gavage one hour after exercise; group R was only given resveratrol 50 mg/kg by gavage; group C and group E were fed normally. The same volume of solvent was given by gavage every day. RESULTS: Resveratrol supplementation could reduce the plasma blood urea nitrogen content, creatine kinase activity, and malondialdehyde content in the skeletal muscle, increase the total superoxide dismutase activity in the skeletal muscle, and improve the fatigue state. Resveratrol supplementation could improve the activities of Ca²⁺-Mg²⁺-ATPase, Na⁺-K⁺-ATPase, succinate dehydrogenase, and citrate synthase in the skeletal muscle. Furthermore, resveratrol supplementation could up-regulate the sirtuin 1 (SIRT1)-proliferator-activated receptor gamma coactivator-1α (PGC-1α)-nuclear respiratory factor 1 pathway. CONCLUSIONS: Resveratrol supplementation could promote mitochondrial biosynthesis via the SIRT1/PGC-1α pathway, increase the activity of the mitochondrial energy metabolism-related enzymes, improve the antioxidant capacity of the body, and promote recovery from exercise-induced fatigue.
