The purpose of this reserch was to oxygen consumption (VO₂), respiratory exchange ratio (RER), heart rate (HR) energy expenditure and excess post-exercise oxygen cosumption(EPOC) of gymnast of elementary school and those of general student of elementary school during 60 minutesafter maximal exercise. Ten gymnasts and the other ten general students participated in the experiment and measured variables before, during and after the exercise. I measured it for 60 minutes after the exercise. Oxygen uptakes when they take a rest is not to eat over 10 hours and arrive at laboratory about 6 o' clock in the morning. And after the arrival at laboratory they lay for 20 minutes to take a rest. I measured EPOC from oxygen uptakes in recovery reduced oxygen uptakes in the rest. According to result of Two-way repeated measures ANOVA and Bonferroni, oxygen intake recovery was not higher(p>.05). But oxygen uptake of gymnasts were significantly higher than those of general students during rest period and post-exercise recovery period. HR of general students was significantly higher than that of gymnasts(p<.05) and rest period between post-exercise recovery period stages were significantly higher(p<.05). RER of gymnastic group was higher than that of general students during recovery period was rest also rest period between post-exercise recovery period was significantly higher(p<.05). After exercise, those of gymnasts(365.68㎖/㎏/min) and general students (365.5㎖/㎏/min) were not higher during 60 minutes of EPOC but it was higer in interval. General students was significantly higher(90.79kcal) that energy expenditure during exercise. Results of this research can be important index for preparing appropriate sports program to prevent fatness by measuring VO₂, RER, HR and EPOC after maximal exercise of children. And I hope that these results can be used for training to modulate weight of gymnasts.

The purpose of this study were to utilization of RPE for exercise intensity of maximal fat oxidation compare during maximal exercise between trained and untrained. The subject of this study were ten athletics(above of VO₂max 60㎖/㎏/min) and ten non-athletics(below of VO₂max 60㎖/㎏/min). Oxygen uptake(VO₂), respiratory exchange ratio(RER), total kilocalories per minute(Tkcal), fat kilocalories per minute(Fkcal) and the rating of perceived exertion(RPE) were measured during the rest 20min and every stages of maximal exercise. The main findings of this study were follows; 1. There was significant difference in oxygen uptake between groups(p<.05), but no significant difference were observed in the respiratory exchange ratio between groups(p>.05). 2. There were significant difference in exercise intensity of maximal fat oxidation and rating of perceived exertion between groups. These results suggest that capability the utilization of rating of perceived exertion for maximal fat oxidation exercise intensity were existent.

The purpose of this study was to identify the change of EPOC according to weight training(60% 1-RM) and submaximal running(60% VO2max). This study was conducted for 10 healthy male college students. Data were processed using the two-way ANOVA. As a result, it there was a statistically significant difference at the level of p<.05 in the period between types of exercise, the post-test was conducted using Bonferroni. It is impossible to judge which exercise of submaximal running and weight training is the one to increase EPOC, but when exercise was performed with the amount of exercise consuming 300㎉, EPOCand the total amount of energy consumption were shown to be higher in submaximal running than weight training. And it was found that the RER was 0.86 in submaximal running and 0.73 in weight training. Accordingly, when submaximal running and weight training were performed with the same amount of exercise able to consume 300㎉, it was found that it was an effective exercise method to perform submaximal running for fat decomposition. To investigate fat oxidation for the resting period using the RER, the fat oxidation rate was shown to be lower after resistance than after submaximal running, for this reason, it would be a more efficient exercise method to using both types of exercise than to perform only submaximal running in terms of fat oxidation.
