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 exer-cise 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 ef-fect on the body of the athletes, which is helpful to athlete training. |
