摘要
通过对单板U型池国家队男子运动员在2010年冬奥会集训期间的身体机能状况和对运动负荷的适应情况进行生物学监控与评价,探寻其变化规律,为教练制定和调整训练计划提供科学依据。方法:以国家队8名男子运动员为研究对象,在不同的集训期对其血清睾酮、皮质醇、肌酸激酶、血尿素和血红蛋白进行测试与评价,测试结果显示:在冬训和夏训期间,运动员的机能状况总体是较好的,但个别队员的体质状况和对运动负荷适应情况及恢复情况波动较大,主要表现在夏训期间的肌酸激酶和血尿素显著升高,而冬训期间则出现低血红蛋白和高血尿素现象。根据其训练的内容,认为夏训期间高强度、长时间的蹦床训练是导致队员血清肌酸激酶和血尿素的主要原因;而冬训期间恶劣的训练环境和大负荷的训练量以及队员饮食条件较差是造成高血尿素和血红蛋白偏低的主要原因。建议:在夏训期间教练应及时调整训练强度,来缓解运动疲劳的状况和机能能力的恢复,在冬训期间要特别注意铁元素、优质蛋白的摄入。此外,应该增加生物学监控的次数,了解运动员的机能状况,及时做出相应的调整,以此保质保量地完成运动训练计划。
The body function and the biological load adaptability of male half-pipe athletes of the national team in 2010 Winter Games were monitored and evaluated to explore the changing reularity and provided scientific basis for coaches to adjust training programs.Methods：eight fine male athletes in China were research objects.In different periods,serum testosterone,cortisol,creatine kinase,and blood urea and hemoglobin were tested and evaluated.The results showed that in winter and summer training,the function of athletes is better,but individual players on the physical fitness and sports load condition were volatile,which was mainly embodied in the content of creatine kinase and blood urea,and significantly increased during the winter training in low hemoglobin and high blood urea phenomenon.According to the summer training,we believe that during the high intensity,long trampoline training is to encourage the players on the enzymes and the main cause of the urea.The serious training environment and large load and bad diet are the main cause of the result of high blood urea and hemoglobin.Suggestions are that in the summer training period coaches should in time adjust the intensity of the training to prevent fatigue to ease the movement of the situation and the ability to function and should be especially caring the iron element and high quality protein in the winter training.In addition,coaches should increase the times of monitoring to understand the situation in the function and to adjust the completion of the movement of training plan under high quality.
