The present study investigated the effect of percent body fat(%fat) on cardiorespiratory function in female university students. Thirty female university students with mean age of 20.6±0.57 years were participated in this study. The subject were divided into three groups according to the level of percent body fat including control group(20∼24.9%fat), overweight group(25∼29.9%fat), and obesity group(30∼ 35%fat). Anthropometric measurements included height and weight. Body mass index was calculated. Percent body fat and fat-free mass were measured by bioelectrical impedance analyzer(Inbody 3.0, Korea). Maximal exercise treadmill test was done by modified Bruce protocol. The test was performed at the speed of 1.7mph on the degree of 0% in the beginning, increasing the speed of 0.8mph and 5% of degree every three minutes. The result of the study showed that significant difference(p<0.01, F=6.227) can be observed between the groups in rest oxygen consumption. Obese group(0.195L·min-1) had highest value of oxygen consumption compared to control group(0.18L·min-1). There was significant difference(p<0.01) between groups for oxygen consumption per lean body mass and oxygen pulse during rest. Control group(4.818㎖·FFM-1·min-1, 2.426㎖·beats-1) showed significant lower value of oxygen consumption per lean body mass and oxygen pulse than the other two groups. On the other hand, no difference were found for carbon dioxide production, respiratory quotient, heart rate and minute ventilation between groups. As a result of this study, it can be suggested that cardiorespiratory function may be influenced by level of percent fat.
