目的:探讨男子散打运动员气体代谢和血液流变性特点。方法:15名男子散打运动员(实验组)和15名普通男子大学生(对照组)进行递增负荷运动,分别于安静状态、运动过程中及运动后即刻测试气体代谢及血液流变学指标。结果:安静时,实验组ηH、ηL、ESR、Arbc、TK、ESRK和EPT显著低于对照组;运动后即刻,实验组ηb、TK、ESRK、EPT较安静时显著增加,但增加幅度显著低于对照组。最大摄氧量时,实验组VO2max、VCO2、VO2/HR、TV和VE显著高于对照组,VEO2显著低于对照组;通气阈时,实验组VT、VO2、VCO2、VO2/HR、VE、TV、RR和METS显著高于对照组,VEO2显著低于对照组。结论:安静状态下,散打运动员全血粘度和红细胞聚集性低于普通大学生,红细胞变形性高于普通大学生;运动后,散打运动员血液流变性优于普通大学生。散打运动员具有通气效率高、氧气利用率高、摄氧能力强的气体代谢特点。
Objective: To investigate the characteristics of gas metabolism and hemorrheology in men’s Sanda athletes. Methods: Fifteen men Sanda athletes (experimental group) and 15 normal male college students (control group) were subjected to progressive load exercise. Gas metabolism and hemorheology indexes were tested during quiet state, during exercise and immediately after exercise. Results: ηH, ηL, ESR, Arbc, TK, ESRK and EPT in the experimental group were significantly lower than those in the control group at rest, while ηb, TK, ESRK and EPT in the experimental group were significantly increased at rest, In the control group. VO2max, VCO2, VO2 / HR, TV and VE in the experimental group were significantly higher than those in the control group at the time of maximal oxygen uptake, while VEO2 in the experimental group was significantly lower than that in the control group TV, RR and METS were significantly higher than the control group, VEO2 was significantly lower than the control group. Conclusion: In the quiet state, the whole blood viscosity and erythrocyte aggregation of Sanda athletes are lower than those of ordinary college students, and the deformability of erythrocytes is higher than that of ordinary college students. After the exercise, the blood rheology of Sanda athletes is better than that of ordinary college students. Sanda athletes with high ventilation efficiency, high oxygen utilization, oxygen uptake capacity of the gas metabolism characteristics.
