亚极量、极量负荷运动状态下人体血中一氧化氮的变化

Changes of quantity of NO in blood of adolescents exercising in submaximum load and maximum load

目的 探讨人体在不同运动状态下一氧化氮 (NO)的变化。方法 应用跑台提供运动负荷，分别对 48名少年进行了安静、亚极量负荷和极量负荷下血中 NO的测定。结果 发现亚极量负荷下血中 NO含量显著高于安静状态时

Objective To probe chages of NO in blood of human body in states of different function.Methods controlling exercise load with treadmill， the quantity of NO in blood of 48 adolescents is determined respectively when they are in rest,Submaximum load and maximum load.Results The quantity of NO in blood during exercise of submaximum load is much higher than that in rest(P
