| 摘 要： | 目的:通过对减体重期运动员力量变化及营养干预效果研究,探讨提高运动员运动能力、充分发挥其竞技水平的方法和手段.实验对象:内蒙古女子柔道队员,按体重随机配对分为普通减重组(n=8)、普通营养减重组(n=8)和营养干预减重组(n=8).实验步骤:实验期为2周,普通营养减重组补充多种维生素及矿物质,另加适量的低聚糖;营养干预减重组除补充多种维生素、矿物质以外,还补充谷氨酰胺等营养补剂.两周训练安排以大强度为主.结果发现:补充无机盐、维生素特别是谷氨酰胺等营养补剂能有效地提高运动员的运动能力,改善运动员的身体机能状态,但是,实验前后各组间运动员的各项峰力矩指标都没有显著性差异(P＞0.05),这在一定程度上表明不能高估补充营养物质的作用.

| Abstract: | Objective: To investigate the methods and means to improve athletes' sports ability and achieve the best performance in competitions by analyzing the athletes' muscule strength change and the effects of nutritional intervention during reducing body weight.Experimental objects: Inner Mongolia female judo Athletes.They are randomly divided into 3 groups: 1.normal reducing weight group(n=8);2.common nutrition reducing weight group(n=8);3.nutritional intervention reducing weight group(n=8).Experimental procedure: The period is 2 weeks.The second group is supplemented with a variety of vitamins,minerals and proper amount of oligosac-charides;The third group is given the same supplements as the second group besides nutritional complements like glutamine et cetera.The athletes are given intensity training during the 2 weeks.Conclusion: To supplement inorganic salts,vitamins,especially nutritional complements like glutamine,can enhance the athletes' sports ability effectively and further improve their physical function.But there are no significant differences between the indexes of peak torque of the three groups of athletes before and after the experiment(p>0.05).The study shows the effect of nutritional supplementing substances cannot be overestimated in some extent. |
