Effects of 12-week circuit weight training and aerobic exercise on body composition, physical fitness, and pulse wave velocity in obese collegiate women

摘要

The purpose of this study was to study the effects of 12 weeks of circuit weight training and aerobic exercise on body composition, physical fitness, and pulse wave velocity in obese collegiate women. Twelve obese collegiate women were randomly assigned either to an exercise training group (TG) or control group (CG). The main exercise program was composed of an approximately 40-65 min session of circuit weight training (resistance training and aerobic exercise) as well as jogging at an intensity of 50-70% of the age-predicted heart rate reserve. The circuit weight training program was made by Korean Institute of Sport Science and was modified as needed for obese collegiate women. All analyses were performed using SPSS and all data was reported as mean ± standard deviation (SD). Significant differences between groups were determined using a two-way repeated measures analysis of variance (ANOVA) with a post hoc test (Tukey method). Statistical significance was accepted for all tests at a value of p < 0. 05. The results indicated that after the 12-week intervention, there were no significant changes in body weight, % body fat, or WC in either group. There was a significant interaction of time by group with respect to body weight (p < 0. 05), % body fat (p < 0. 01), and WC (p < 0. 01) and there was a significant change in back strength between the TG before beginning the program and the TG after having completed the program (p < 0.01). There was also a significant interaction of time by group with respect to back strength (p < 0.01), grip strength (p < 0.05), sit and reach (p < 0.01), sargent-jump (p < 0.01), and the one leg balance with eyes closed (p < 0.01); however, these differences were not statistically significant between groups. Further, there was a significant interaction of time by group with respect to the 1,200 m run for cardiopulmonary endurance (p < 0.01); however, this difference was not statistically significant between the TG pre and TG post. In addition, there was a significant in sit-ups (p < 0.01) and the 1,200 m run (p < 0.01) between the TG and CG. There was no significant difference in side-steps between the TG and CG. Further, there were no significant differences in the pulse wave velocity, RPP, SBP, DBP, and MAP between the TG and CG. In conclusion, circuit weight training and aerobic exercise had favorable effects on the occurrence of obesity and physical fitness in obese collegiate women.
