摘　　要：以宁夏区体委自行车队运动员为受试对象，将其随机分为二组：对照组和试验组（口服１０％的宁夏枸杞鲜汁饮料，相当于服用５０ｇ枸杞鲜汁１ｄ）。实验前后，分别让运动员在功率自行车上以逐级递增负荷的方式运动至力竭，测定最大耗氧量（ＶＯ＿２ｍａｘ）及全血ＳＯＤ、ＧＳＨ－ＰＸ、ＭＤＡ血乳酸等生理、生化指标，以观察宁夏枸杞的清除活性氧及抗疲劳作用。结果表明：实验组全血ＳＯＤ活性比对照组明显增强（Ｐ＜０．０５）；血乳酸含量明显降低（Ｐ＜０．０５）；宁夏枸杞能明显抑制ＭＤＡ的生成。提示宁夏枸杞具有清除活性氧及抗疲劳作用。For the purpose of studying resisting fatigue effect and anti-oxidantion effectof Lycium barbarum L.(LBL), a number of professinal cyclists were divided into twogroups randomly,one group taking LBL juice orally(equivalent to 50 g LBL juice/d),while the other group taking blank juice both for 20 days.The cyclists rode on a power cy-cles everyday, their loads being kept going up grandually to exhaust the cyclists,their max-imum oxygen comsumption the activities of blood SOD, GSH-PX and MDA,lactic acidcontent were determined.The results showed that the activities of SOD,GSH-PX andmaximum oxygen consumption were high but the lactic acid wes low in the LBL group,it issuggested that LBL could play an important role in resisting fatigue effect and anti-oxida-tion effect in vitro.
