摘要
目的:调查西藏登山运动员与同年龄普通大学生有氧运动能力的差异及其相关影响因素。方法:研究对象为西藏登山运动员49人,随机抽取西藏大学学生34人作为对照;均数间比较采用独立样本T检验;有氧运动能力(最大摄氧量)相关因素分析采用多元线性回归;P<0.05为具有统计学意义。结果:西藏登山运动员的有氧运动能力显著优于对照组西藏大学学生。结论:高原训练可以促进血液中血红蛋白浓度的增加,从而提高机体运输氧的能力,进而增强机体抵抗缺氧的耐受性。
In the present study,difference in the aerobic capacity between Tibetan alpinists and college students with the same age as these alpinists is studied and the effect factors causing the difference is investigated.49 ex?isting Tibetan alpinists aged 20-26 and 34 randomly selected college students from Tibet University were com?pared.In the present study,difference in mean values of two groups was tested using a one-way ANOVA.Linear regression model was constructed to determine the relationship between the outcome variable(maximal oxygen uptake)and the selected covariates.And it was defined as statistically significant if P<0.05 in the present study.The results show that the aerobic capacity of the Tibetan alpinists is significantly better than that of the control group of college students from Tibet University.It is can be concluded that altitude training can promote the in?crease of hemoglobin concentration in the blood,and thus improve the oxygen-carrying capacity of the body,re?sulting in enhancing the resistance to hypoxia tolerance.
