The 12 week, self-managed, community-based, stretching exercise program was effective to increase flexibility. The standard stretching intervention without any enhancements may be a more cost-effective way to increase flexibility. Longitudinal studies, however, are needed to see if the long-term effects are greater in the enhanced intervention for the migrant worker population.

The purpose of this study is to examine the effect of Prunus mume supplementation on changes of energy substrate (glucose, FFA) and fatigue factors (lactate, ammonia, phosphorous) in the performance of exercise. The subjects of this study were 15 male university students. The exercise test was performed for 30 minutes at 75% VO2max on the treadmill and conducted both before and after administering Prunus mume for 6 weeks. Through Prunus mume supplemntation, the accumulation of such fatigue factors as lactate, ammonia, and phosphorous along with concentration of glucuse decreased, but the concentration of FFA increased. From the study, it can be seen that Prunus mume plays a positive role for the use of energy substrates and accumulated fatigue factors.

-The purpose of the present study was to examine effect of 12 week regular aerobic exercise on ST-segment and QTc interval in middle age type 2 diabetes mellitus (T2DM) patients. The subjects consist of 13 type 2 diabetes mellitus (T2DM) patients in middle age men and all of them had no other complications.Subjects participated in aerobic exercise training for 12 weeks. They started to exercise for 20～60 min at 60～80% of HRmax (exercise intensity has been increased gradually) per day, 3～5 times a week. The results were compared before and after. Weight and BMI, % body fat, fasting glucose, HOMA-IR, peakDBP were significantly decreased and peakHR, peakVO2, exercisre time were significantly increased after 12 week aerobic exercise. Also, QTc interval and ST-segment were significantly decreased during at rest, peak exercise after 12 week aerobic exercise. Conclusionally, 12 week aerobic exercise may be improvement in decreased cardiovascular mortality factors (ST-segment) and abnormal autonomic dysfunction (QTc interval) and potentially increased exercise capacity.
