女子摔跤运动员减重训练期营养水平及血液生化指标变化

采用实验法,了解女子摔跤运动员减重训练阶段膳食营养水平和血液生化指标的变化。结果显示:在减重训练期,运动员体内的蛋白质、碳水化合物、维生素A及钙等摄取不足,且血清钙、铁水平下降,而血清尿素含量和肌酸激酶活性显著升高。提示:通过限制饮食减重期间,要注意蛋白质、钙、铁及维生素的补充,同时在此期间营养生化的监控有助于科学合理的减重。

Nutritional Level and Change of Blood Biochmical Indications of Female Wrestlers in Their Training Period with Reducing Body Weight
