摘要
为更科学地对竞走运动员进行营养干预,并为提高运动成绩提供实验依据,选取中国国家竞走队男女运动员各12人(共24人)进行实验.时间为9周,同时进行多种运动补剂营养干预,在1、3、5、7、9周末进行血睾酮(testosterone,T)、血尿素(blood urea,BU)和血清肌酸激酶(creatine phosphokinase,CK)等指标测试.结果表明:不同运动补剂配伍服用可以提高男女竞走运动员的血睾酮水平,促进机体内蛋白质的合成和机能的快速恢复;降低大强度训练后次日晨血清CK水平和BU水平异常,减轻运动员的疲劳程度,从而保证训练任务的顺利完成和竞技水平的正常发挥.不同运动补剂配伍服用可以改善生物化学指标,全面提高男女竞走运动员的身体机能水平.
To more scientific nutritional intervention on the walking athletes to improve athletic performance and provide experimental evidence. 12 male and 12 demale selected from the Chinese national walking team were given the nutrition intervention of a variety of sports supplements for 9 weeks. The serum testosterone （ T）,serum urea （blood urea,BU）,and serum creatine kinase （creatine phosphokinase CK） and other indicators were tested at 1、3、5、7、9 weekend. The results showed that the different exercise taking supplements can increase the T levels of male and female walking athletes,and promote the body protein synthesis and the function of rapid recovery,reduce the levels of serum CK and BU abnormalities after the intensity training,and ensure the smooth completion of the training and a normal competitive level. The different exercise taking supplements can improve the biochemical indicators and improve the level of physical function.
