서킷웨이트 트레이닝과 웨이트 트레이닝이 비만 남자대학생의 유산소성 운동능력과 건강관련체력에 미치는 영향

Abstract

The purpose of this study was to investigate the effects of circuit weight training and weight training on aerobic capacity and health-related fitness in obese male college students. In this study 16 obese male college students attending G-city University without medical history were selected as subjects. These subjects were randomly assigned to circuit weight training group (n=8) and weight training group (n=8). The subjects in circuit(three circuits using a work-to-rest ratio of 30s:30s) and weight training program performed for 8 weeks, 3 times a week on non-consecutive days at 40 and 80% of one-repetition maximum(1RM), respectively. The maximum oxygen uptake(VO₂max) and oxygen uptake(VO₂) at anaerobic threshold(AT) were measured as the aerobic capacity. Also, body composition, muscular strength, and muscular endurance were measured and analyzed as the health-related fitness. Based on the results of the study, the following results were obtained. First, the maximum oxygen uptake and oxygen uptake at anaerobic threshold were significantly increased (p<.01) in the circuit weight training group, but there was no significant difference in the weight training group. Second, there was a significant decrease (p<.01) in body weight in the circuit weight training group, and a significant decrease (p<.001) in body fat(%) in both groups. In contrast, lean body mass was increased in both groups, but there was no significant difference. Third, There was a significant difference (p<.001) in muscular strength and muscular endurance in both groups. Therefore, circuit weight training may also be an effective exercise method for increasing potential aerobic capacity and reducing body fat in changes in body composition.
