一次性大运动量训练后不同时相机体免疫机能的变化

Change of Immune Function of Male Junior Sprinters after Once High Load Training

目的:研究短跑运动员在大运动量训练后不同时相的细胞和体液免疫状态,以监控运动训练的科学性和合理性。方法:观察了15名青少年男子短跑运动员在一次性大运动量训练前后免疫球蛋白IgA、IgM、IgG、白细胞数及IL-1的变化,分析短跑运动员的运动训练水平。结果:大运动量训练后,运动员免疫球蛋白即刻有不同程度下降,而白细胞数和IL-1水平均有不同程度上升,但调整后各项免疫指标恢复。结论:采用监控运动员免疫指标变化的手段能客观、准确地评定运动员在运动训练过程中免疫状态的改变,为教练员及时调整运动员训练强度,保证训练的系统性和科学性提供依据。

In order to study the change of immune function of junior male sprinters after once high load training, methods： 15 Male junior sprinters are subjected to high load training. The indexes of lgG, IgM, IgA, WBC and IL-1 under three time points after training are analyzed. Results： After training, the above-mentioned indexes changes immediately and recovers after 24 hours. These changes may reflect the immune function of junior male sprinters. Conclusion： The results suggest that athletes＇ immune indexes can indicate their status during training and provide evidence to adjust their training load for the systematic and scientific training.
