The purpose of this study is to examine the effective exercise intensity for the prescriptions between people of normal weight and who are obese. Selected for the purpose of the study were 10 male residents (age, 23±2.2 years) of Seoul. The participant are normal weight rage whose % Body fat is less than 20% and 10 male residents who were considered obese with %Body fat of 23%~30%. In the first test, the participant walked on the treadmill using Bruce protocol until they were all-out to get the maximal oxygen consumption. In the secondary test, in order to calculate %VO₂R by exercise intensity corresponding to the each subject's exercise intensity level of 30%VO₂R, 35% VO₂R and 40%VO₂R, %VO₂R formula (%VO₂R=%VO₂max-(1MET=3.5 ㎖/㎏/min)×Ratio+%VO₂rest) was applied the maximal oxygen consumption which was gained from the fist test. And then, the intensity wan adjusted manually. During the 30-minute experimental procedures the respiratory exchange rate (RER) was within 0.7~1.00. The results were explained below. Firstly, during the sub-maximal exercise, based on the intensity and the participant's %Body fat, significant differences in the rate of breathing could be observed within, and between the two groups, at exercise intensity of 30%VO₂R, 35% VO₂R and 40%VO₂R (p<.001). Secondly during the sub-maximal exercise, the calories burned by the group of normal weight, whose ability for oxygen intake is greater than the obese group was significantly higher (p<.001). Thirdly, when the rate of fat consumption and that of burning were compared between the two groups during the sub-maximal exercise, both groups showed significant result at the exercise intensity of 30%VO₂R and 35% VO₂R (p<.01), and also at the intensity of 40%VO₂R (p<.001). Fourthly during the sub-maximal exercise based the intensity and %Body fat, no significant differences were apparent at the exercise intensity of 30%VO₂R, hoewer, at the exercise intensity of 35% VO₂R the result in the normal weight and the obese, showing significant differences (p<.01), and at the 40% VO₂R the results were even more significant (p<.001). Fifthly, during the sub-maximal exercise based on the intensities and %Body fat, there were significant differences in the heart rate and heart beat at different exercise intensity (p<.001). As a result, in order to develop and prescribe a suitable exercise regimen, it is important consider many factors such as age, sex and individual physical abilities.
