摘要
目的研究湿热环境下运动前后人体血液流变学的改变情况。方法选取90名南沙巡防区战士,分成老兵组、新兵组、新兵服药组(口服乌拉地尔片剂)3组,在湿热环境下20min内跑步3000m,抽血测定跑步前后的血液流变学的改变。结果跑步前后3组之间血液流变学指标均有显著差别,但跑步后3组之间改变的幅度不一样,其中新兵组幅度最大,老兵组其次,新兵服药组幅度最小,而3组之间的血浆指标无显著差别。结论湿热环境下运动对人体血液流变学的影响较大,新、老兵在此环境下出现的耐受和适应情况不同,口服乌拉地尔片剂可以降低和减少运动前后的血液流变学指标改变幅度。
Objective To observe the changes in hemorheology of human under hot and humid environment. Methods Ninety soldiers serving in the Nansha Islands were divided into veteran group, recruit group and urapidil-treated recruit group, all of whom were required to complete 3 000-meter running exercise in 20 min in hot and humid environment. Their hemorheology were examined before and after the exercise. Results There were significant difference in the hemorheology between the 3 groups (P<0.05) both before and after the exercise, and the changes were most obvious in the veteran group followed by the new recruit group and urapidil-treated recruit group. No significant differences in the plasma indexes were detected between the 3 groups. Conclusions Hot and humid environment causes obvious changes in the hemorheology, for which veterans and recruits have different tolerances and adaptabilities. Uradipil may help lower the magnitude of the the hemorheological changes after exercise by reducing body metabolism.
