摘要
为中国国家自行车队8名女子500m计时赛运动员备战第28届奥运会进行了小周期训练结合生理生化监测。通过公路无氧阈强度训练,使国家队女子500m计时赛运动员有氧氧化酶的活性提高,血液与氧结合能力的代偿性增大,血液运氧能力提高。在训练期间,运动员着重进行了原地500m×4组耐乳酸训练,经过耐乳酸训练后,运动员血乳酸峰值明显提高。结论1)冬训中通过无氧阈训练可以提高自行车场地女子500m计时赛运动员有氧能力;2)耐乳酸能力的提高是女子500m计时赛运动员取得成绩的关键,良好的有氧能力和无氧能力是场地女子500m计时赛运动员必需具备的专项生理机能;3)在同样负荷的情况下,经过一个冬训周期的训练,女子500m计时赛运动员的血清CK值明显下降;4)由于耐乳酸训练强度大,冬训持续时间长,女子500m计时赛运动员疲劳有一定程度积累;5)应用无氧阈、耐乳酸训练、血乳酸、血清CK、UREA等生理生化指标对优秀女子500m计时赛运动员评定是可行的。
In order to realize the goal of getting the gold medal of woman 500m time trials in Olympic Games, the research group improves the training method and increase the athletic ability during training and competition. The main purpose is to make cyclist participating in competition with the best conditioning. 8 cyclists in woman 500m time trails of national cycling team are training for micro- cycle combining with physiological and biomechanical measurement. The result shows that through intensity training of anaerobic threshold on the road, the anaerobic threshold speed and capacity of oxygen transportation are steadily increased. During the winter training, cyclists are emphasized on lactate tolerance of 500m× 4 sets training,the peak value of cyclist＇s blood lactate is significantly increased,the va,lue of creatine kinase is decreased. The level of UREA is slightly increased before and after winter training. It concludes that aerobic capacity of cyclists in woman 500m time trails increases by training the anaerobic threshold during winter training, The increasing of lactate tolerance capacity is the key of achieving the performance in woman 500m time trails. It is feasible to use the physiological and biochemical indexes such as anaerobic threshold, lactate tolerance training,blood lactate,serum CK and UREA to evaluate the elite cyclists in woman 500m time trails.
