| 摘 要： | 目的：探讨有氧耐力训练对运动热应激大鼠肾脏组织NO、NOS及自由基代谢的影响。方法：对大鼠进行为期6w的递增负荷运动训练，并在运动末次施加热应激，测定大鼠肾脏组织NO、NOS、MDA和SOD含量或活性。结果：（1）运动加热应激使大鼠肾脏组织NO、NOS、iNOS和MDA显著高于安静组和急性运动组，SOD和SOD／MDA显著低于安静组和急性运动组；（2）训练安静组与安静对照组相比，MDA均显著下降，NO、NOS均显著上升；（3）训练后运动热应激大鼠肾脏组织NO、NOS、iNOS、MDA显著下降，SOD显著上升。结论：（1）在热环境下运动，机体NO、NOS和自由基代谢增加，抗氧化酶活性下降；（2）在常温下进行有氧耐力训练练，可以适当提高机体的耐热性，降低运动热应激对机体的损伤。

| Abstract: | Objective:Explore the effects of aerobic endurance training on NO,NOS and free radical metabolism in kidney of mice after exercise plus heat stress.Methods:Mice were trained on treadmill for six weeks with incremental exercise and were exerted on heat stress in the last training.Results:(1)After exercise plus heat stress,NO content and NOS and iNOS and MDA activity were increased more than those of the control group and exercise group.SOD and SOD/MDA were decreased less than those of the control group and e... |
