The purpose of this study was to examine the effects of two different exercise volume (HVE; High-Volume resistance Exercise, 10-RM/6set. LVE; Low-Volume resistance Exercise, 10-RM/3set:) on several hormones. Nine healthy men (Age; 25.3±0.2 years, Hight; 175±1.1 cm, Weight; 67,4±1.5 kg) volunteered to participate in this study. Pre-and postexercise (0, 15, 30, 60fnin, 24h) blood samples were obtained and analyzed for glucose, lactate, creatine kinase, growth hormone, testosterone, cortisol. Post exercise values for glucose and lactate were significantly (p<.05) elevated above preexercise value for both treatment, and significantly higher in LVE ton HVE Significant increases in creatin kinase activities were observed after 24h postexercise for both treatment, and significantly higher in HVE than LVE. Plasma growth hormone level was significantly increased after exercise for both treatment, and significantly greater in LVE than HVE. Plasma cortisol level was increased after HVE at the immediate postexercise time point, and significantly greater in HVE than LVE at 30min postexercise. No significant changes in plasma testosterone level were observed with two treatment Thus, These data indicate that exercise volume is a more important component of hGH, cortisol release than the exercise intensity.
