The purpose of the present study was two folds: first, to examine the pattern of changes in physiological variables manipulated by the level of aerobic exercise intensities (40%, 55% and 70% of ？o₂ max); second, the effects of the physiological variables on the volume of EPOC. The physiological variables of interest in this study were respiratory gas (？o₂, heart rate, RQ), blood lactate and glucose, serum lipids(TG, FFA), and blood gas(pH, PO₂, PCO₂, EPOC(volume, maintain time)).
The subjects in this study were ten female university students majoring physical education. Their age ranged from 21 to 23 years old. Before the experiment starts, maximal load test was performed from all the subjects in order to determine individual-specific maximum oxygen consumption. During the experiment, the subjects exercised for 20 minutes on the treadmill at each level of exercise intensities. After exercise, the end-point of recovery period was determined by the point which the ？o₂ returned to the level of rest. Two-way ANOVA with repeated measures on both factors and correlation analyses were conducted to obtain the results of the experiment.
From these analyses the following conclusions was attained:
1. The mean value of EPOC during the recovery period was the highest at the 70% of exercise intensity, followed by the 55% and the 40% (6.34 ㎉). As expected, the mean value of energy consumption during the exercise period showed the same pattern.
2. The time taken from the end-point of 20 min exercise to the level of rest significantly increased as the level of exercise intensity increased.
3. The value of EPOC was positively related to the values of blood epinepirine, triglyceride, pH, PO₂ among the 26 measured physiological variables for all three level of exercise intensities.
From these results, it can be suggested that when we evaluate the total amount of exercise expenditure during 20-min exercise with the exercise intensity of 40%, 55%, and 70% of ？o₂max, we should include the amount of EPOC (about 5% - 10%) consumed during the recovery period. Moreover, it was found that the energy consumption was maintained at least 15 to 50 minutes after the end of exercise period when the aerobic exercise was conducted for 20-min with 70% (or less) of ？o₂ max.
