The purpose of this study was to investigate the ralationship between aerobic work capacity and body fat distribution in 31 college distance runners, averaged 15'23"4±21"6 with 5000 m running performance Aerobic work capacity was measured on a bicycle ergometer by the multistage test. Body fat distribution was estimated by D_2O dilution method and by measurement of skinfold thickness at 12 sites. The mean VO_2 max were 3659.7±369.9 ml/min and 63.6±5.1ml/kg/min, respectively. The total body fat and percent body fat were 11.3±2.6 kg and 19.4±4.1%, respectively. In addition, body fat distribution were 2.4±0.9 kg (4.1±1.5%) with subcutaneous fat and 8.9±2.4 kg (15.3±3.9%) with internal fat. Total body fat, percent body fat, and subcutaneous fat negatively correlated with VO_2 max (r=-0.370〜-0.453, p<0.05). On the other hand, lean body mass (kg) was most strongly related to the absolute value of V0_2 max (r=0.634, p<0.01). The results of this study suggest that endurance training done by distance runners decreases subcutaneous fat, and that the more lean body mass might have an influence on aerobic work capacity.
