지구성훈련이 최대운동부하 후 혈중 글루코스,젖산,인슐린 및 에피네프린의 변화에 미치는 영향

Abstract

The purpose of this study was to investigate the effect of endurance training on blood glucose, lactate, insulin and epinephrine of endurance-trained athletes(ETG) and untrained male(CG) to acute gradual maximal exercise. The subjects for this study were 12 endurance-trained athletes and 10 healthy male university students who participated in this experiment voluntarily. Each subjects performed to exhaustion gradual maximal exercise test on treadmill. Blood samples were collected at rest, immediately exercise, and 30min recovery. In the present results, the blood glucose showed significant increase at immediately exercise compared to rest and 30min recovery in the two groups. The blood lactate showed significant increase at immediately exercise compared to rest and 30min recovery, and at 30min recovery than rest in the two groups. The blood insulin at immediately exercise were significantly low in the ETG compared to the CG, and there were significant increase at immediately exercise compared to rest and 30min recovery in the CG, and showed significantly higher at 30min recovery than rest in the ETG. The blood epinephrine were significantly high in the ETG compared to the CG at immediately exercise, and showed significant increase at immediately exercise compared to rest and 30min recovery in the two groups. In conclusion, the results of this study suggest that the endurance training may induce effective energy changes during acute gradual maximal exercise.
