通过PHA淋巴细胞转化试验 ,选取刺激指数 (SI)反映T淋巴细胞功能 ,观察有氧运动和训练过程中T淋巴细胞功能的应答与适应特点。 16名未经体育专业训练的普通女大学生进行 8周有氧训练 ,每天 30分钟。结果显示 :(1)作为对一次运动的应答 ,运动后即刻SI值均出现明显下降 ,但在训练的前两周 ,运动后 1小时后未见恢复且继续下降 ,从第 6周末起 ,运动后 1小时SI值已基本恢复 ,表现为一条“V”形曲线。 (2 )作为对长期有氧运动的适应 ,随时间推移 ,第 1周至第 4周末SI值均显著低于训练前水平 (P <0 .0 5 ) ,至第 6周末基本恢复到训练前水平 ,上述结果可能与神经系统的免疫调节作用、应激激素的免疫抑制作用、免疫系统的自身调节以及免疫系统对神经系统、内分泌系统的反调节作用有关。
Through the PHA lymphocyte transformation test, select the stimulation index (SI) to reflect the function of T lymphocytes and observe the response and adaptation characteristics of T lymphocyte function during aerobic exercise and training. 16 non-physical training of ordinary female college students for 8 weeks of aerobic training, 30 minutes a day. The results showed that: (1) As a response to one exercise, the SI value decreased immediately after exercise, but no recovery was observed one hour after exercise and continued to decrease in the first two weeks of training. From the end of the sixth week, exercise After 1 hour SI value has basically recovered, showing a “V” -shaped curve. (2) As the adaptation to long-term aerobic exercise, the SI values from week 1 to week 4 were significantly lower than those before training (P <0.05) over time, and returned to pre-training levels by the end of the 6th week The above results may be related to the immune regulation of the nervous system, the immunosuppressive effects of stress hormones, the self-regulation of the immune system and the anti-regulatory effect of the immune system on the nervous system and the endocrine system.
