摘　　要：目的研究游泳与健美操相结合的有氧运动对女大学生心脏功能及T淋巴细胞亚群的影响。方法选取女大学生志愿者60人,随机分为对照组、30分钟运动组和60分钟运动组,测定运动前后安静心率、心功指数、T淋巴细胞亚群(CD4+、CD8+、CD4+/CD8+)含量。结果两组运动组均未影响安静心率,但均显著改善心功指数,且60分钟组的改善结果显著优于30分钟组(P<0.05)。两组T细胞亚群CD4+、CD4+/CD8+T比值明显高于对照组(P<0.05),60分钟有氧运动CD4+T细胞比例显著高于30分钟组(P<0.05)。结论游泳与健美操相结合的有氧运动可改善女大学生心脏功能和T淋巴细胞免疫功能,且60分钟运动的改善效果优于30分钟运动。Objective To investigate the effects of swimming and body building exercise on cardiac and immune functions in female college students. Methods 60 normal female college students were randomly divided into three groups： control, 30 min exercise group and 60 min exercise group. Rest heart rate, basic heart rate and T lymphocyte sub-group （CD4^＋ ,CD8^＋ ,CD4 ^＋/CD8 ^＋ ） were measured. Results 30 min and 60 rain exercise significantly enhanced cardiac functions as evidenced by improved heart index （P 〈 0. 05）, but it did not affect the rest and basic heart rates. Moreover, improvement of heart index in 60 rain exercise is better than in 30 min exercise （ P 〈 0. 05 ）. Compared with control group, 30 rain and 60 rain exercise groups significantly increases CD4 ^＋ , CD4 ^＋/CD8 ^＋ and decreases CD8 ^＋ level （P 〈 0. 05 ）, and 60 vain exercise showed a better improvement than that in 30 min. Conclusion Swimming and body building exercise could effectively enhance the cardiac and immune functions in female college students.
