| 摘 要： | 以6名上海优秀男子散打运动员为研究对象,对赛前体重控制、运动能力和体液离子变化情况进行研究,每周3次体脂率测试;每2周测试1次无氧运动能力和体液离子情况。结果显示,第3周体重和体脂率显著下降(P<0.05),第5周体重发生高度显著变化(P<0.01),体脂率和瘦体重显著下降(P<0.05);无氧运动能力在整个控重过程无显著变化(P>0.05);第3周Na+升高非常显著(P<0.01),Ca2+显著升高(P<0.05),CO2CP下降(P<0.05),第5周Na+浓度有所下降但仍高于控重前(P<0.05),Ca2+显著升高(P<0.05),CO2CP明显下降(P<0.01)。研究表明通过延长整理活动和增加有氧训练课可以实现运动员控重以消耗脂肪为主的目标,能够保证运动员无氧能力不损失,通过电解质饮料补充能够维持队员机体内环境的稳定。

| Abstract: | In order to study before-competition body weight control and the changes of sports capacity and body fluid ions,by basing their research objects on 6 excellent male free combat players in Shanghai,the authors meas-ured the body fat rate 3 times every week,and the anaerobic sports capacity and body fluid ions once every two weeks,and revealed the following findings:in the 3rd week,the body weight and body fat rate decreased signifi-cantly(P<0.05);in the 5th week,the body weight had a very significant change(P<0.01) and the body fat rate and lean body weight had a significant change(P<0.05);the anaerobic sports capacity had no significant change(P>0.05) in the entire process of body weight controlling;in the 3rd week,the concentration of Na+ increased very significantly(P<0.01),the concentration of Ca2+ increased significantly(P<0.05),the concentration of CO2CP de-creased(P<0.05);in the 5th week,the concentration of Na+ decreased somewhat but was still higher than that before body weight controlling(P<0.05),the concentration of Ca2+ increased significantly(P<0.05),the concentration of CO2CP decreased significantly(P<0.01).The said findings indicated that prolonging the time for after-exercising activities and increasing the time of aerobic training classes can realize player body weight control mainly based on consuming fat,and ensure that the players have no loss of their anaerobic sports capacity,while supplementing elec-trolyte drinks can maintain the stability of the internal body environment of the players. |
