【摘要】 流式细胞仪检测受试者在12周有氧和气功训练前后安静状态下和大强度运动后细胞免疫各指标。结果:(1)不管是否经过训练,各组CD8在大强度运动后即刻均呈上升趋势(P<0.05),CD4/CD8则均呈下降趋势(P<0.05);(2)组内比较,有氧组和气功组训练后安静状态下的CD4、CD8显著低于训练前,而两组的CD8对大强度运动的反应则显著高于训练前,三组的NK细胞数量在大强度运动后即刻均显著上升(P<0.05);(3)组间比较,训练后有氧组的CD8对大强度运动的反应显著高于对照组和气功组,CD4/CD8则显著低于对照组和气功组,NK细胞数量显著高于气功组。更多还原

【Abstract】 Twenty four healthy elderly females underwent immune function tests before and after strenuous physical stress.They repeated these tests after 12 weeks of aerobic and qigong training.Results:(1) CD8 response to strenuous physical stress increased obviously among the three groups while CD4/CD8 ration showed a trend of decrease(P<0.05).(2) CD4 and CD8 under quiet status of aerobic and qigong training groups after training were lower than that before training.The response of CED8 and NK cell number to strenuous physical stress increased significantly(P<0.05).(3) CD8 response to strenuous physical stress in aerobic group was higher while CD4/CD8 ration was lower than those of the other groups.Its NK cell number was much more than that of qigong group.更多还原
