체지방에 따른 오전과 오후의 산소섭취량, 심박수, 혈압의 변화

Abstract

The purpose of this study was to investigate the effect of body fat on energy metabolic response and subjectivesensations under the hot environment. Fifteen female university students volunteered as subjects. We organized subjects . 30% of body fat) and high body fat group(group H: more than 30% of body fat). The experiment was conducted with 32oC, 60%RH. The subjects repeated Exercise and Rest period. The results of this study are as follows ; The oxygen uptake value of AM is higher than PM. The value of group H is the highest in three fat groups. But it showed group L is the highest in oxygen uptake per weight. %body fat is the lower, oxygen uptake is the higher. In Calorie, group L has higher value in AM in than in PM. In M group and group H, a value of PM is higher than AM. In group H, diference of AM and PM is the highest. From a view point of thre groups, a value of group H is the highest. This support that calorie increases as oxygen uptake increase. The heart rate values of group L and group H are the higher in AM than in PM. This support that heart rate was relation to oxygen uptake. In all three groups, the value of blood pressure is higher in sensation are higher in Am than in Pm. This explains that subject sensations are similar to experimental data, such as oxygen uptake, heart rate, blood pressure. In oxygen uptake, heart rate and blood pressure, general tend to showed higher AM than PM. This showed that heart rate, oxygen uptake increase in AM, as blood pressure increase, too. From a view point of %body fat, group H is higher than the others in oxygen uptake, heart rate and blood pressure.
