Bioelectric activity of a brain and cerebral hemodynamics in skiers of military age over seasons of the year

INTRODUCTION: The heavy training load in extreme climatic conditions of the European North inevitably requires adaptive reactions from the athlete’s body, consequently, influencing on functional performance of the central nervous system.

OBJECTIVE: To identify the patterns of seasonal changes of bioelectric activity and cerebral hemodynamics in skiers of military age.

MATERIALS AND METHODS: The study involved 20 skiers of military age. The study was conducted over a year and included 4 stages, relevant to athletes’ preparation stages. In the course of work the indicators of bioelectric activity and brain cerebral hemodynamics were registration, using electroencephalograph NMG «Neurocartograph-8» and reograph «Diamant-R». Psychological status assessment was conducted using the anxiety and depression test, according to the method of A. A. Karelin.

RESULTS: As a result of the study, it was found that skiers of military age experience deterioration in cerebral hemodynamics and brain bioelectric activity with the increase in training and negative factors of the North.

CONCLUSION: Functioning of the athlete’s body in the European North results in deterioration of cerebral hemodynamics and brain bioelectric activity and increase of anxiety-depressive conditions in the winter preparation stage.
