备战2008年奥运会国家男子举重队运动员亚高原训练效果评价

Evaluation of Sub-Altitude Training of Chinese Men's Weightlifting Team Preparing for 2008 Olympic Games

为了探讨亚高原训练对血液生化指标的影响,本文系统观察了6名国家男子举重队优秀运动员进行4周亚高原(847m)训练前后血红蛋白(Hb)、红细胞数(RBC)、白细胞数(WBC)、红细胞压积(HCT)、肌酸激酶(CK)、血尿素(BUN)血清睾酮(T)、皮质醇(C)的变化,并进行了对比分析。研究发现:(1)白细胞水平呈先下降再升高现象;(2)血红蛋白水平升高,并在亚高原训练期间维持较高水平;而红细胞数目和红细胞压积未见明显提高;(3)血清肌酸激酶水平升高并持高值;血尿素水平总体趋势呈现低-高-低;(4)睾酮水平与血清皮质醇呈先下降再升高现象。结论:亚高原训练能明显提高举重运动员血红蛋白水平,提高训练负荷刺激强度,提高运动员机能能力;不利方面是疲劳恢复较慢,睡眠较差,免疫力降低,精神兴奋性也有所下降等。

In order to study the effects of sub-altitude training on blood biochemical indicators, Hb, RBC, WBC, HCT, CK, BUN, T and C of 6 men＇s weightlifters of the Chinese National Team were systematically observed before and after the 4-week sub-altitude training（847m）. The result shows the following： 1. WBC first decreased and then increased. 2. Hb increased and was at a relatively high level during the period of subaltitude training. No significant difference was observed in RBC and HCT. 3. CK increased and kept at a high value. BUN was frst low, then high and then low again. 4. T and C first decreased and then increased. The conclusion is that sub-altitude training may significantly increase the weightlifters＇ Hb, improve the training load stimulation and enhance the athletes＇ fitness. The disadvantage lies in slow recovery, poor sleep, lower immunity and low excitement.
