In principle, at rest, there may not be a direct causal relationship between the characteristics of SCP and the biochemical indicators of energy metabolism in peripheral blood. Despite the significance of the concentration of hydrogen ions for the SCP value, there may be no direct correlation between the SCP and the pH of the peripheral blood, since the question of the content of hydrogen ions in the blood flowing from the brain remains unknown. With other indicators of energy metabolism in peripheral blood, the situation is even less certain. In the absence of load in ordinary people, the stability of biochemical parameters is ensured by buffer systems and other regulatory mechanisms, and the parameters of SCP may reflect the characteristics of cerebral metabolism, which is not directly related to the biochemical characteristics of peripheral blood. However, for athletes who have been under continuous physical exertion for a long time, the biochemical parameters of peripheral blood, as well as the work they perform, depend on the level of stress, which affects both the biochemical kinetics and the athlete’s achievements. If any sporting event is especially significant for the athlete, and the necessary psychocorrectional measures were not taken in such cases, then the AMR for such athletes increased significantly. At the same time, as already mentioned, the ANSP decreased and usually the results of such athletes were lower than those shown by athletes with less pronounced stress. Therefore, in the case of stressful loads, statistically significant correlations between SCP and some peripheral blood biochemical parameters are possible.
We have identified numerous correlations between different indicators of SCP before and after exercise and a number of biochemical characteristics in athletes. However, an analysis of the correlation matrices in men and women indicates that there is no unambiguous relationship between the characteristics of SCP and biochemical parameters, since in men and women these relationships are significantly different. In addition, the patterns of correlation, indicating the relationship of biochemical parameters among themselves, vary significantly between men and women, i.e. The laws of biochemical kinetics are different for them. One might think that this is due to both gender differences and initially different levels of stress.
Men and women have relatively few matching paired correlation coefficients between SCP and biochemical parameters. But in cases where such a coincidence takes place, the values of the correlation coefficients are close in magnitude and identical in sign .
The correlation between the characteristics of AMR and biochemical indicators common to athletes of men and women
F # – local potential in the frontal region, CO, C-Td, O-Td – SCP differences between C – central, O – occipital, Td – right temporal regions. AMP – adenosine monophosphate; P un – inorganic phosphorus; m – men, w – women.
As you can see, there are three stable correlation between biochemical parameters and SCP. Of these, the most significant and practically useful is the relationship between pH and F # (local SCP in the frontal region). Apparently, the frontal areas are more sensitive than others to stress caused by a shift in the acid-base balance of the blood to the acidic side. The important role of the frontal cortex, in particular, of its orbital departments in the regulation of homeostasis is known. Under stress, it is the SCP in the frontal area that correlates with the Kerdo index, which characterizes the tone of the autonomic nervous system. The found correlation dependence indicates that under conditions of high motor loads, it is the front sections of the brain that work in a particularly intensive mode, which ensures targeted activity of the athlete.
