摘　　要：研究了逐级递增负荷力竭性运动对短跑运动员自由基代谢的影响。结果表明:逐级递增负荷力竭性运动使机体脂质过氧化反应明显加强,自由基防御体系协同完整的抗氧化能力明显降低,但运动对不同的抗氧化剂影响是不同的;尿液MDA含量、尿液T-SOD活力是反映自由基代谢状态的灵敏指标。This paper observed the changes of free radical metabolism of college athletes after incremental-load exhaustive exercise.The results show that,lipid peroxide increases significantly after incremental-load exhaustive exercise,T-AOC in serum decreases significantly after exercise;effects of incremental-load exhaustive exercise on antioxidants are different;T-SOD activity and MDA in urine are sensitive to exercise.

关 键 词：逐级递增负荷力竭性运动 自由基代谢 短跑运动员
