摘　　要：目的:研究以备战十二庙全运会浙江省场地自行车短距离组运动员为研究对象,通过冬训期间生化指标的测试,探讨和试图发现冬训引起自行车运动员身体机能的变化规律,达到在冬训期间对运动员的身体机能和训练强度进行有效的监控和调整的效果,为自行车项目的体育科研实践提供一定的理论依据。方法:在整个冬季训练周期内,对自行车运动员的Hb、BUN、CK、T四项指标进行系统的长期监控。结果:冬训前后自行车运动员Hb、BUN、CK、T处于正常标准范围,在整个冬训期间,Hb、BUN、CK、T随运动负荷的变化经历了周期性变化,其中BUN和CK均出现显著性差异(P<0.05)或非常显著性差异(P<0.01),而Hb和T(除第3周外)均未出现显著性差异(P>0.05)。结论:①冬训期间运动员Hb、CK、T随运动负荷的变化而变化,女子运动员对上述生化指标的敏感度要高于男子运动员。②BUN维持在一个较高的水平上可能并不会对场地自行车短距离运动员的运动成绩带来太大的影响。③由于运动员所能承受的负荷量和强度都不尽相同,相同负荷量和强度所产生的机能反应也不会相同,进一步分析时需要结合个体生理生化指标和训练计划完成情况进行综合考虑,从而提高测定分析的准确性。Objective： The research took the bicyclists in Zhejiang for preparing of the Twelth National Games in winter training as the subjects. Through biochemical index of testing during the winter training, we attempted to find out some rules or problems by exploring the characteristics of their training during winter training. Reached on body func- tion and the training intensity of athletes for effective monitoring and adjustment effect during winter training, and to provide a reference for the development of scientific in bicycle training. Methods：During the long term bicycle train- ing,some physical fitness evaluation indices including Hb, Bun, CK and T were tested and analyzed systematically. Results.. Hb,Bun,CK and T based standard value in the normal range, throughout the winter training period, Hb, BUN and CK,and T has experienced cyclical changes along with the change of sports load during the winter training. The BUN and CK are significant difference （P〈0. 05） or very significant difference （P〈0. 01）,while the Hb and T （Except the third week） there was no significant difference （P〈0.05）. Conclusion：@During the winter training ath- letes Hb, CK and T changes over motion load, NEUT ~//00 can be used as auxiliary training monitoring indexes of female athletes on the biochemical indexes of the sensitivity is higher than male athletes. @Blood urea to maintain at a high level of cycling short athletes may not bring much impact performance. @Because of the mobilization can bear the load and strength are not the same, the same load and intensity produced by the reflect function will not the same, further analysis is needed to combined with physiological and biochemical indexes and individual training plan situation carries on the comprehensive consideration, so as to improve the accuracy of measurement analysis.
