低氧训练对中长项目自行车运动员生理生化指标的影响

目的:探讨低氧训练模式对运动员生理生化指标的影响。方法:实验为期4周,采用低住高练,常氧训练为主,低氧运动为辅的训练方式,每周测定血液生理生化指标。结果:低氧训练期间两组运动员的WBC均先降低后升高。RBC、Hb、Hct均明显升高,且女性增高幅度大于男性;训练结束后一周,男性较训练前无显著性差异,而女性则明显高于训练前。男性运动员在整个低氧训练期和结束训练后CK和T均未出现显著性变化,BUN仅在低氧训练第4周和训练结束后一周显著性增加。女性运动员CK值从低氧训练第3周开始显著性降低;BUN则在整个低氧训练期和结束训练后一周显著性增加;T值仅在训练结束后显著增加。

Effects of Hypoxic Training on the Physiological and Biochemical Indexes for Elite Middle and Long Distance Cyclists

Objective ：To investigate the effect of hypoxia training on athletes＇ physiological and biochemical inde- xes. Methods ： The experiment lasted for 4 weeks, living low and training high. normoxic training primarily, supple- mented by hypoxia exercise training, weekly determination of physiological and biochemical indexes of blood. Re- suits ： During the hypoxia training the WBC of the two groups of athletes decreased at first and then increased. RBC, Hb, and Hct were significantly higher in women than men. A week after training no significant difference was ob- served in men than before training, while in women the three indexes were significantly higher than before training. Male athletes did not show significant change in CK and T in the hypoxia training period or after the training, and BUN only increased significantly a week after the training and in the fourth week after training. CK in female ath- letes decreased significantly from the third week after the training ,while BUN increased significantly in the hypoxic training period and one week after. T value increased significantly only after training.
