摘　　要：目的:探讨减体重对女子柔道运动员机能状态的影响。方法:上海市女子柔道队12名运动员随机分为减重组(6人)和对照组(6人),从赛前1个月(包括减重第一、二、三阶段和减重末期)开始进行生理、生化指标的跟踪测试,并进行统计学处理。结果:减重组在前3个阶段体脂%下降与减重前比较差异有显著性(P<0.05),在减重末期去脂体重、背力和握力与减重前和对照组比较差异均有显著性(P<0.05)。在减重末期,减重组血红蛋白(Hb)、红细胞(RBC)和红细胞压积(Hct)与减重前及对照组比较差异均有显著性(P<0.05)。减重组血尿素氮(BUN)在第三阶段和减重末期与减重前比较差异有显著性(P<0.05),在减重末期与对照组比较差异有显著性(P<0.05)。在减重末期,减重组睾酮(T)和皮质醇(C)与减重前及对照组比较差异均有显著性(P<0.05)。结论:女子柔道运动员赛前减体重可引起机体内生理和生化指标的变化,导致机能状态和运动能力的下降。Objective To examine the effects of weight loss on functional state of female judokas. Methods Twelve female judokas belonging to Shanghai female judo team were tested at different periods（first,second,third phases and last phase） during weight loss a month before competition. The changes of physiological and biochemical indexes in different periods were observed and all the data was statistically analyzed. Results Previous three phases,the Fat% in weight loss group was decreased compared with basic data （P〈0.05）; at the last phase,the lean body weight（LBW）,back power and grip power were decreased compared with basic data and control group （P〈0.05）. Compared with basic data and control group,the hemoglobin （Hb） and RBC in weight loss group were decreased,then the hematocrit（Hct） was increased （P〈0.05）. Compared with basic data,the blood urea nitrogen（BUN） in weight loss group was decreased at the third phase （P〈0.05）. At the last phase,BUN and cortisol （C） in weight loss group were increased,then testosterone（T） was decreased compared with basic data and control group （P〈0.05）.Conclusion Weight loss before competition has the effects on physiological and biochemical indexes,which lead to the decline of functional state and exercise ability of female judokas.
