不同运动负荷对少年速度轮滑运动员免疫系统机能和血清生长激素水平的影响

Effect of Exercise Training with Different Loads on Serum GH and Immune Function in Juvenile Speed Roller Skaters

选择少年速度轮滑运动员,对其安静状态及不同负荷强度训练后即刻的血液免疫球蛋白、T细胞亚群、NK细胞的比例,血清生长激素等指标进行了测试及相关分析。结果表明,不同运动负荷对少年速度轮滑运动员机体免疫功能的影响出现双向效应,低强度的运动训练可以保持或改善机体的免疫功能,而长时间、大强度的运动可以引起机体免疫功能的抑制或免疫调节功能的紊乱。而对生长激素则可引起明显的升高,但二者之间未发现明显的相关关系。

The serum growth hormone （GH）, T cell subpopulations, the percent of NKcell in peripheral mononuclear cells and immune globulin system receptor level immediately after speed roller skaters training. The results showed that intense speed roller training could cause significant immune suppression on the juvenile speed roller＇s immune system, but increase the level of serum GH. No significant relation was observed between the immune suppression and the increase of the serum GH level.
