단시간의 고강도 서킷 트레이닝이 비만 남자 직장인의 신체조성, 혈중지질 및 체력에 미치는 영향

The purpose of this study was to investigate the effects of a short-term high-intensity circuit training on body composition, blood lipid profile and physical fitness in obese men office worker. Eighteen obese men office worker (BMI 〈25 kg/m²) were randomly assigned to high-intensity circuit training group (HICT, n=13) and control group (CON, n=5). High-intensity circuit training was consisting of 30-minute exercise session, 3-4 times a week, for 12 weeks. Body composition, blood lipids profile and physical fitness were measured before and after high intensity circuit training. Body weight, BMI and body fat were significantly decreased in HICT after circuit training than at before circuit training (p〈.01). TG was significantly decreased in HICT after circuit training than at before circuit training (p〈.05), and TC tended to be reduced than at before circuit training (p=.053). Squat (p〈.05), sit-up (p〈.01) and push-up (p〈.01) were significantly increased in HICT after circuit training than at before circuit training. However, all parameters in CON were not significantly different at between times. These results of this study may suggest that short-time high-intensity circuit training improves body composition and blood lipids, and increase physical fitness.
