Introduction

In resent years, altitude training has become an often-used method before competition. There are many studies on altitude training in fields of physiology, biochemistry, molecule-biology and so on. As the development of system science, especially, as the knowledge of system is used in nerve science, the effect of altitude training on performance should be evaluated in a new way. Unfortunately, the study on altitude training and the relation to controlling training state with the idea of system science has not been reported. Therefore, we designed this experiment from the point of self-organization in which many physiology and biochemistry index are observed.

Methods

In this experiment, We make determination of biochemistry index, immunity index, the ability of self-adjustment of brain and athletes’ test result before, in altitude training and 1day and 12days later after altitude training,, during which 9 excellent athletes are experimented.

Results

The result shows that: (1) some athletes’ test result rise, but the others’ go down during the altitude training. In the national sport competition after altitude training,, 6 out of 10 athletes’ match result descend. Meanwhile, we found that the level of hemoglobin lactate( HL) also shows a decreasing tendency after altitude training. (2) The value of hemoglobin( Hb) and white blood cell(WBC) all indicate that the athletes’ organism show a low adaptability to lower oxygen content, but the fountain of respondency to stimulation increase. The level of testosterone (T) in plasma has no significant change during the altitude training. But it appears an obviously decreasing tendency after altitude training. Before match, its value almost reach the original level as its before. (3) The change of distribution of encephalo-electricity oscillatory cycle indicates that the concentration degree of performance information entropy go down. This anticipates that some athletes do not get good result in competition.

Discussion / Conclusions

From this study, we get two conclusions. First, altitude training can’t replace the specially designed training before match. The duration of effect of altitude training depends on the training plan before match and scheme in intensity during altitude training. Second, all the indexes of brain function, such as information entropy dispersing,dominant oscillatory level of information entropy dispersing or shift to right, have indicated descent of athletes’ sport ability. The ordinary index in biochemistry and physiology, such as Hb, urea nitrogen in serum (Bun) etc, can only reflect ordinary function of athletes’ organism. They have no linear relationship with athletes’ sport ability.
