체지방률이 35% 이상인 비만여중생 7명을 대상으로 주4회 1회40분, 1∼6주는 %HRmax 50∼60%, 7∼16 주는 주5회, 1회 40분, 60∼70%로 에어로빅스 트레이닝을 16주간 실시하여 체중, 체지방량, 체수분량과 복부의 피하지방과 내장지방 및 인슐린 농도에 미치는 영향을 연구하여 체중은 1.73㎏, 체지방률은 5.92%(p<.05), 체지방량은 1.83㎏의 감소를 나타내었다. 복부의 전체지방은 47.02㎤, 피하지방은 27.72㎤, 내장지방은 19.3㎤(p<.05), V/S 비는 0.03이 유의(p<.05)하게 감소되고 인슐린 농도는 11.91μIU/ ㎖가 유의(p<.01)하게 감소되어 장기간의 에어로빅스 트레이닝이 비만 여중생의 비만치료와 예방에 긍정적인 효과가 있는 것으로 사료된다.

The purpose of this study was to investigate the effect of aerobics training on abdominal fat and insulin concentration. Subjects were composed of fourteen obese middle-school student. Aerobic training was performed 40minutes per day, 4days per week at 50∼60%HRmax during 1∼6weeks and at 60∼70%HRmax during 7∼16weeks. The items for abdominal fat volume were measured subcutaneous fat volume(SFV), visceral fat volume(VFV), VFV/ SFV by computed tomography. Paired t-test was used to evaluate the difference of baseline and after 16 weeks aerobics training. The 0.05 level of significance was as critical level for the study. The results of this study are as follow; 1. Weight(㎏), %body fat(%), fat mass(㎏) were significantly decreased after 16 weeks aerobics training. 2. VFV, SFV and VFV/ SFV were significantly decreased after 16 weeks aerobics training.. 3. Insulin concentration was significantly decreased after 16 weeks aerobics training. In conclusion, visceral fat was decreased and Insulin concentration was decreased in aerobics training. So it is maybe thought that aerobics training improved body composition for obesity treatment.
