Effect of Continuous Exercise at Different Intensity on Respiratory and Blood Gas Component , Serum Lipids , Catecholamine and EPOC

The purpose of this study was to examine the pattern of changes in physiological variables manipulated by the level of aerobic exercise intensities such as 40 %, 55 %, and 70 % of VO_2 max and to evaluate the effects of the physiological variables on the volume of EPOC. From these analyses, the following conclusions were 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%. 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, PO_2 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 minutes exercise with the exercise intensity of 40%, 55%, and 70% of VO_2 max, we should include the amount of EPOC about 5-9% more.
