博士 === 中國文化大學 === 體育學系運動教練碩博士班 === 105 === Inadequate physical activity and obesity are associated with the mortality and morbidity of chronic disease. It has a positive meaning through exercise training to reduce the risks. In recent years, circuit training is an important option to offer people maintain a healthy lifestyle. Purpose: To explore the effect of circuit training on body composition (body weight, muscle mass, body fat percentage, waist to hip ratio and BMI) and muscular strength performance (grip strength, back muscle strength and lower limb muscle strength). At the same time, observed the change in related blood parameters of body composition (hs-CRP, TC, and LDL) and muscular strength performance (IGF-1) in middle age sedentary female workers. Methods: Thirty-six faculty of university aged between 40-64 years old were recruited into this study. The subjects were randomly divided into circuit training group (CT), aerobic training group (AT) and control group (CON). The training groups were conduct 8 weeks of training, 3 times a week. In CT group, each cycle of circuit training was 8 mins, 2 sets each training session, 4 mins rest between sets, a total of 20 mins in 1-4 weeks. And 3 sets each session, 5 mins rest between sets, a total of 35 mins in 5-8 weeks. In AT group, 1-4 weeks training by aerobic training for 20 mins, and 35 mins in 5-8 weeks. The two exercise training groups were given a 5-minute dynamic stretching and relaxation exercise before and after each training session. The pre- and post-test of the physiological indicators were executed a week before and after the training. The blood collection should fast for 12 hours. And the statistical analysis was using two-way mixed design ANOVA, to compare the difference on body composition, muscular strength performance and related blood indicators between the three groups before and after the training. Results: After 8 weeks of training, the muscle mass and knee extension at 60o/s were significant improve in CT group, and the knee extension at 60o/s in CT group was significant better than AT group. In AT group, the body weight was significant decreased. However, the indicators in CON group were no significant change. In addition, the body fat percentage, waist to hip ratio, BMI, grip strength, back muscle strength and related blood parameters were no significant change, and there were no significant difference between groups. Conclusions: After the 8 weeks of circuit training, it could effectively improve the muscle mass and lower limb muscular strength. And the aerobic training could effectively decrease the body weight. In addition, the circuit training and the aerobic training had no significant effect on the related blood parameters TC, LDL-C, hs-CRP and IGF-1 in this study.
