운동강도 차이가 혈중 에너지 기질 및 호르몬 반응에 미치는 영향

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the effect of different exercise intensity on energy substrates and hormone responses. The subjects for this study were 10 healthy male college students, and participated in three exercise trials. At each trial, subjects ran on the treadmill at the respective exercise intensities corresponding to 40%(low), 60%(moderate), 80%(high) of VO2max for 30min bout of acute exercise. The order of the trials was randomly assigned into three exercise intensities by one week. Blood sample was taken from antecubital vein at rest, immediately after exercise, and recovery 30 min. The results of this study are as follow; The concentration of FFA was significantly increased at post-exercise more than rest and recovery 30 min at 40%, 80% of VO2max, and recovery 30 min at 60% of VO2max. The concentration of insulin was significantly decreased at post-exercise more than rest and recovery 30 min at 40%, 60%, 80% of VO2max. The concentration of epinephrine was significantly increased at post-exercise more than rest and recovery 30min at 60%, 80% of VO2max, and in the effect of exercise intensity, at 80% intensity was higher than at 40%, 60% intensities at immediately after exercise. The concentration of norepinephrine was significantly increased at post-exercise more than recovery 30 min at 60% of VO2max, rest and recovery 30 min at 80% of VO2max, and in the effect of exercise intensity, at 80% intensity was higher than those at 40%, 60% intensities, and at 60% intensity was higher than those at 40% intensity at immediately after exercise. In conclusion, the concentration of energy substrate, insulin, epinephrine, and norepinephrine were affected by various exercise intensities.
