비만 초등학생의 산소섭취량과 심박수 및 RPE 변화에 관한 연구

The purpose of this study was to examine the changes of oxygen uptake, heart rate and RPE in obese elementary school students. fourteen subjects participated in the present study. The subjects of this study was divided into two groups; one group was obese elementary school students(OB=7); the other was normal elementary school students(NO=7). Before the test, all subjects were medically examined, the experimental protocol was explained and their written consent was obtained. fourteen elementary school students performed maximal treadmill exercise test according to the GXT protocol(Bruce). They were verbally encouraged and possible until the maximum was achieved. maximal treadmill exercise tests were conducted in the exercise physiology laboratory of Department of Physical Education at Kangnung National University.<BR> 1. The changes of VO2 is higher on NO group (non obesity) than OB group (obesity) and there were significant different in the changes of VO2 between groups(p＜.05).<BR> 2. The changes of HR is higher on OB group than NO group however there was no significant different in the changes of HR between groups(p＞.05).<BR> 3. The changes of RPE is higher on OB group than NO group and there were significant different in the changes of RPE between groups(p＜.05).
