摘要
本实验研究旨在观察红细胞免疫功能对有氧运动的适应性变化特征。10名未经训练的大学女生作为受试者,连续从事有氧运动 30 d,每日 30 min。分别于第 1日、第 10日、第 20日与第 30日抽取当日测试负荷前(活动跑台,8 Km.h^(-1),0°,15min)、负荷后即刻及恢复1h静脉血样,进行红细胞免疫功能测试。结果发现:①有氧运动可提高红细胞免疫功能对同一运动负荷的反应性;②CR_1 活性随有氧运动进行呈先上升后复归趋势;RFER(促进因子)及 RFER/RFIR 呈持续升高趋势,RFIR(抑制因子)则呈持续降低趋势。③红细胞免疫功能对有氧运动的适应性变化大致可分为激活、补偿、去补偿及复归4个阶段。
This study aims at observing the time course of adaptive changes of erythrocyte (red blood cell) immunity to aerobic exercise. 10 non-trained female college students served as subjects and executed an aerobic exercise program of 30 minutes daily for 30 days. Three venous blood samplings were taken before testing load (8km/h, 0(, 15min on treadmill), just after load and after 1hour recovery at the 1st, 10th, 20th, and 30th day of aerobic exercise respectively, the results suggested that CR1 activity rose in first days and fell gradually in the following days along with the aerobic exercise, and that RFER and RFER/RFIR rose gradually and RFIR showed an opposite trend. Adaptation of erythrocyte immunity to aerobic exercise could be divided into four phases: activation, compensation, decompensation and restoration.
