摘要

本研究的目的在探討單次急性衰竭運動是否會造成氧化傷害，以22位17-18歲的橄欖球選手為對象，進行高強度的原地跑步機運動至衰竭，運動負荷設計如下：0-3分鐘-6公里／小時、3-5分－9公里／小時、5-7分－11公里／小時、7-9分－13公里／小時、9分鐘以後皆以14公里／小時的速度跑至衰竭。比較橄欖球選手在運動前後丙二醛(MDA)濃度及超氧化歧化酶(SOD)活性的變化，並測量運動前後血乳酸、肌酸激酶的變化。實驗結果顯示運動後運動員MDA平均濃度顯著增加，SOD活性顯著比運動前減低。而運動後血乳酸值及肌酸激酶顯著增加。顯示實驗設計的衰竭運動強度會造成運動員的氧化壓力，使其MDA增加，而SOD活性降低，高強度的運動雖然持續的時間較一般衰竭運動短，但仍然造成運動員的氧化傷害。

The purpose of this study was to evaluate whether an acute single bout of strenuous exercise would induce oxidative stress. Twenty-two male rugby players served as the subjects for this experiment. The subjects performed an acute period of exhaustive exercise on a treadmill, with the exhaustive exercise starting at 6 km/hr for 3min followed by gradual increases of treadmill speed and times to 9km/hr for 2min, 11km/hr for 2min, 13km/hr for 2min, and 14km/hr until exhaustion. Blood samples were collected at rest and immediately after exhaustive exercise for measurements of malondialdehyde (MDA), superoxide dismutase (SOD) activity, lactate, and creatine kinase (CK). The results showed that there was a significant increase in the plasma MDA, lactate, and CK after exhaustive exercise. SOD activity showed a significant decrease after exhaustive exercise. The results suggest that a single bout of exhaustive exercise can induce oxidative stress and decrease the SOD activity for well-trained rugby players.
