Introduction

The objective of this study is to learn more about the level of self-adaptation to the exercise load in athletes by monitoring the cerebral entropy in athletes, using the latest achievements in neuroelectrophysiology and system science to test and analyze the value of the cerebral entropy in athletes, through comparison of the value of the cerebral entropy in athletes in different events at different levels, in combination with a contrastive analysis of training levels and sports results, etc., to achieve the goal of quantitative control of sports training.

Methods

The experimental subjects in this study were short-distance race, swimming, water ballet, pentathlon and trampoline athletes. The RJTBʽ1 advanced sports training state (cerebral) monitoring instrument was used to test the cerebral entropy in athletes, following a clinical routine. Those subjects with abnormal routine EEG were ruled out.

Results

The test data were statistically treated. As viewed from the average and standard deviation of the value of the cerebral entropy in athletes, athletes in different events had different values of the cerebral entropy. The values of the cerebral entropy were minimum in the swinging athletes, showing a good self-organizing state of sports training because all the subjects were state-class masters of sports or masters of sports. As viewed from the degree of discretion of the sample, the trampoline athletes showed the minimum degree of discretion because these trampoline athletes tested were at a near level. The T test on the distribution of the value of the cerebral entropy in adjacent cerebral regions in athletes in the same event showed that there was a significant difference between the right and left cerebellums only in the trampoline athletes, with more concentrated values of entropy in the left cerebellum than the right one, possibly because the left cerebellum participates more in attention control, while trampoline is an athletic event that needs high level of concentrated attention. Neither the swimming athletes nor the short-distance race athletes had a significant difference between cerebral regions, showing a good equilibrium state in the entire brain.

Discussion/ Conclusions

The cerebral entropy can, to a certain extent, reflect the level of self-adaptation to the exercise load in athletes; the good self-organizing state of the entire brain in the athletes is manifested not only as the equilibrium distribution of the entropy in the entire brain but also as the high concentration of the entropy; the cerebral entropy in the athletes has obvious individual characteristics and event characteristics; the cerebral entropy can be used as one of the ideal evaluating indicators of the degree of self-adaptation to the sports training load in athletes, particularly for reasonable follow-up monitoring in athletes, which will play a more practical role in directing sports training.

Key words: cerebral entropy athlete self-adaptation evaluating indicator
