12주간의 훈련프로그램이 생리주기에 따른 난소 및 성장 관련 호르몬, Cortisol에 미치는 영향 = Effects of 12wks Training Program on Menstrual Cycle in Ovarian and Growth Related Hormone and Cortisol

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the effects of 12 weeks training program to menstrual cycle (mense and luteal phase) on VO2max, percent body fat, circulating concentration of ovarian hormone (estrogen, progesterone), cortisol and growth related hormone (growth hormone; GH, testosterone). Twenty-two female participated in this investigation and were divided control (n=11) and training groups (n=11). Venous blood samples were obtained during luteal (21day after mense), and early follicular phase (during mense) before and after training. Training consisted of treadmill running (15-25minutes) and resistance training which include leg curl, leg press, full down, curl up, sit up with 10 repetition maximum (3set) respectively. 12 weeks training programs significantly decreased body weight and body fat(%). but VO2max increased significantly after training. After 12 weeks training program GH concentration was significantly increased both mense and luteal phase but cortisol concentration was significantly decreased only in luteal phase. Estrogen and progesterone concentration were significantly elevated in luteal phase in contrast of mense in all group but exercise training did not induce any significant change. Serum cortisol concentration significantly decreased during luteal phase in contrast of mense after 12 weeks training but GH, testosterone concentration did not induce any significant change with menstrual cycle. In conclusion, 12 weeks training program enhanced growth related hormone and cortisol response and this training induced change differed between mense and luteal phase.
