对比了 9名女子 4 0 0m跑运动员补体系统与正常人的差异及观察了同一批运动员在模拟比赛和大运动量训练前后补体系统的变化。结果显示 :安静状态下女子 4 0 0m跑运动员C4显著低于正常人 ;大运动量训练后即刻C3升高 (P <0 .0 5 ) ,C4显著升高 ,增幅达 4 7% (P <0 .0 1) ,C4经 3h及 2 4h恢复后仍高于运动前(P <0 .0 5 ) ;模拟 4 0 0m跑比赛未能引起补体系统的变化。提示 :安排大运动量训练时 ,必须充分考虑补体系统的应答及恢复特点 ,以便改善训练效果。 The differences between the complement system of 9 women 400-ran runners and normal subjects were compared and the changes of complement system in the same batch of athletes before and after the simulation games and large amount of exercise training were observed. The results showed that C4 was significantly lower in normal women than in normal subjects at 4 0 0m runners in quiescent condition, C3 was increased immediately after heavy exercise training (P <0. 05), and C4 was significantly increased by 47% (P <0 .0 1), C4 was still higher than that before exercise after recovery for 3h and 24h (P <0.05). Simulated 4 0 0m race did not change the complement system. Tip: When arranging a large amount of exercise training, the response and recovery characteristics of the complement system must be fully considered in order to improve the training effect.
