摘　　要：马拉松运动员李柱宏为了备战北京奥运会,在海拔1 750 m的兰州愉中亚高原进行了为期4周的针对性训练,为了解李柱宏在亚高原训练中运动负荷对机体的刺激程度,掌握亚高原运动训练的规律,对李柱宏在亚高原不同训练负荷阶段尿常规指标和部分生化指标进行了跟踪检测,结果发现:不同运动负荷和强度对红细胞数无显著影响,大运动量训练可使血清尿素氮和肌酸激酶水平升高,睾酮和皮质醇比例明显升高,运动后恢复正常;运动负荷前后尿比重、酮体、亚硝酸盐及白细胞无显著变化;运动后尿蛋白、隐血、胆红素、尿胆元水平上升。说明通过生化指标的检测与分析发现,亚高原训练能对运动员的机体产生较为深刻的影响,对运动员的训练是有益的。For preparing for the Beijing Olympic Games, marathoner LI Zhu-hong carried out 4-week action specific training on a sub highland 1750 meters above sea level in Yuzhong, Lanzhu. In order to understand the degree of simulation produced by exercise loads subjected to LI Zhu-hong during sub highland training to his body, and to grasp sub highland training patterns, the authors tracked and tested conventional uric indexes and some biochemical indexes of LI Zhu-hong at different training load stages during sub highland training, and revealed the following findings： different exercise loads and intensities have no significant effect on the number of red blood cells; training with high exercise intensities can increase the levels of serum urea nitrogen and creatine kinase, and significantly increase the percentages of testosterone and cortisol, which recovered their normal levels after exercising; there is no significant change in specific gravity of urine, acetone body, nitrite and white blood cells before and after exercise loads; the levels of urine protein, occult blood, bilirubin and urine bladder essence increase after exercising. It is discovered via biochemical index test and analysis that sub highland training can produce a relatively profound effect on the body of the athletes, which is helpful to athlete training.
