在广州优秀男子青少年足球运动员不同负荷训练阶段,用血红蛋白、血尿素、CK、血睾酮等生化指标对运动员进行身体机能分析,防止运动疲劳。研究结果表明:不同训练阶段训练任务和负荷不同,生化指标的变化也不同,在实际运用中,要把几个生化指标结合起来进行综合分析,才能反映运动员的真实身体机能状态。 At the stage of different load training of elite male soccer player in Guangzhou, the physical function of athletes was analyzed by using biochemical indexes such as hemoglobin, blood urea, CK, blood testosterone to prevent the movement fatigue. The results show that the training tasks and loads are different in different training phases, and the biochemical indexes change differently. In practice, it is necessary to combine several biochemical indicators to make a comprehensive analysis to reflect the athlete’s physical function.
