为探讨递增负荷运动过程中少年男篮血浆NO含量和NOS活性的变化规律,选取少年男篮运动员12名,普通健康少年学生12人作为对照组,同时进行递增负荷运动。测试结果表明:少年男篮组在安静时的NO的含量和NOS活性比普通少年组高(P<0.05);运动后即刻各组NO的含量和NOS活性均升高,男篮组升高率大于普通组;恢复期各组NO的含量均降低,男篮组的恢复速度大于普通组。说明运动可以提高人体血清内NO的含量以及NOS活性;在运动过程中,有训练史者调节NO代谢的能力增强。

To investigate the changes of plasma NO and NOS activity in juvenile male basketball during incremental load exercise, 12 juvenile male basketball players and 12 normal healthy juvenile students were selected as control group, and at the same time, progressive load exercise was performed. The results showed that NO content and NOS activity in the juvenile male basketball team were higher than those in the normal juvenile group (P <0.05); NO content and NOS activity in each group were increased immediately after exercise, Which was higher than that of normal group. The content of NO in recovery group was lower than that of ordinary group. It shows that exercise can improve the content of NO and the activity of NOS in human serum. During the exercise, the ability of training history to regulate NO metabolism is enhanced.
