Purpose: This study was to investigate the effect of a 12-week plyometric training on body composition, physical fitness and bone mineral density in obese male adolescents. Method: Twenty adolescent boys who are obese were randomly assigned to a control group (CON, n=10) or plyometic exercise group (EXE, n=10). The EXE group was performed 3 times per week for 12 weeks. The body composition, physical fitness, and bone mineral density were measured before and after the 12 weeks intervention. Results: The results of this study were as follows: i) In EXE group, the fat mass was significantly decreased between pre and post, whereas the difference of the body weight, BMI, and LBM were not significant. ii) Among the physical fitness factors, grip strength, muscular endurance, and 2 0m shuttle running were significantly improved but flexibility did not show any significant difference. iii) The bone mineral density was significantly improved between pre and post in EXE group. Conclusion: These results suggested that plyometric training for 12 weeks may be effective in improving body composition, physical fitness, and bone mineral density in obese adolescents. Further implications were discussed.

PURPOSE: This study examined the effectiveness of an active lifestyle on the HRV and fitness of the older female adults. METHODS: Eighty female older adults (72.68±3.78 years) were sampled from a senior wellness institute. Accelerometers were distributed to each participant to have the device attached to them for one week, and the physical activity data (Energy expenditure in Kcal) of each participant were analyzed. Participants were divided into 3 groups (<1,000 Kcal vs 1,000 to 1,500 Kcal vs ≥1,500 Kcal) based on the amount of weekly physical activity. Before and after data analysis, the HRV was measured at resting state and the Senior Fitness Test was performed. RESULTS: One way ANOVA showed a significant difference in the HRV between the three groups. Group A (≥ 1,500 Kcal) was superior in HF and HF/HF + LF whereas Group C (<1,000 Kcal) showed high level of LF, LF/HF, and LF/HF+LF. The same statistics revealed significant differences in fitness. Most of the fitness variables were superior in Group A and B compared to Group C. Significant correlations were observed between physical activity and both HRV and in fitness. CONCLUSION: Theses results suggest that an active lifestyle may be an effective intervention for the prevention of both cardiometabolic disorder and improvement of the fitness level in older female adults.

In a TV component manufacturing factory, 102 male workers aged $20{\sim}39$ years old were participated in testing for physical fitness. At the same time, worker's periodic health examination was done. Test battery for physical fitness include grip strength, trunk flexion, standing long jump, side step, single leg balance with eye close, push ups and Harvard step test. As a result of testing for physical fitness, synthetically, there is no difference between manufacturing workers and officers. By bioelectrical impedance test, it means a declining tendency to all 7 factors in the obese workers, and so, it is important for obese workers not only to promote physical fitness but also to promote health. Excluding grip strength and single leg balance with eye close, 5 fitness factors are negatively associated with degree of diastolic Blood pressure, but it is statistically not significant. And levels of sGOT & sGPT have no association with physical fitness factors.
