| ［摘要］目的 应用玛咖进行抗疲劳动物实验，为相关部门开发新型的运动补剂提供参考．方法 将30只SPF昆明种雄性小鼠随机分为安静对照组（A组）、力竭运动组（B组、高海拔）、玛咖+力竭运动组（C组），每组各10只；另加力竭运动组（D组、低海拔）20只．C组在饮用水中溶入玛咖，浓度为5%．30 d后，进行一次力竭实验，测定力竭时间，即刻处死小鼠测试T-SOD、肝糖原等生化指标．结果 C组小鼠力竭游泳时间比B组长且差异有统计学意义（P＜0.05），T-SOD比A组和B组高差异有统计学意义（P＜0.05），肝糖原含量比B组高且差异有统计学意义（P＜0.05）．D组小鼠力竭游泳时间比B组长且有统计学意义（P＜0.01）．结论 玛咖能够提高T-SOD活性，提高肝糖原含量，具有较好的抗疲劳作用；低海拔地区小鼠力竭游泳运动时间高于高海拔地区小鼠． |

| Abstract: |
| ［Abstract］Objective To establish the resist-fatigue animal test through using Maca， in order to provide reference for the relevant departments to exploit new sports nutrition . Methods Thirty male KM mice were randomly divided into Quiet control group（A），Exhaustive group（B，high altitude），Maca exhaustive group（C）， there were 10 mice in each group. Drinking water containing Maca（Maca =500 mg/L）was supplied in group C. Additional exhaustive group（D，low altitude）was set．Thirty days later， all mice were killed after one exhaustive test， then we tested the exhaustive time，the level of T-SOD and liver glycogen. Results The exhaustive time of group C was significantly longer than group B（P＜0.05）， the T-SOD level of group C was significantly higher than group A and group B（P＜0.05）， and the liver glycogen content of group C was significantly higher than group B（P＜0.05）. Conclusion Maca can raise T-SOD and liver glycogen level of the mice after exhaustive swimming， and has function of resist-fatigue. |
