The purpose of present study was to investigate the effects of exercise and electrical stimulation on maximal exercise capacity, lipid metabolism and hormonal changes. The subjects of this study were 21 women who never had been participated in any exercise training program. They were divided into three groups randomly; Group 1(LF=7) was electrical stimulation experimental condition; Group 2(EX=7) was bicycle exercise experimental condition at 60% of maximal exercise capacity; Group 3(EX+LF=7) was exercise and electrical stimulation experimental condition. Blood sample were drawn from antecubital vein before and after taking part in the different experimental conditions. There were significant difference in the maximal exercise capacity among experimental conditions(p<.05). The changes of weight and fat free mass were more decreases in the EX group than other experimental conditions(p<.05). There were no significant difference in the blood TG and epinephrine concentration among experimental conditions(p>.05). However, there were significant difference in the blood free T3 and norepinephrine concentration among experimental conditions(p<.05). The results of this study indicated the regular exercise might be induced the increase of maximal exercise capacity. Also, the regular exercise could play role in the important physiological function of normal lipid metabolism. Therefore, it is suggested that exercise more efficient effector to improve the functional capacity of exercise and lipid metabolism in young women.
