Actual problems on adaptation of sportsmen to strenuous training and competetive effect in high performance sport

The problem of adaptation, acclimatization and reacclimatization comprises the basis of transition, restructuring and redistributive processes in the circulatory and respiratory systems, in humoral and hormonal changes, enzymatic changes, neuromotor regulations. Specialized clarification of the study on body composition, enzymatic influence, statokinetic stability, integration of metabolic processes, energy supply, micro- and macro element effect, gas exchange, tissue oxygen transport function is needed. The struggle for oxygen, energy supply is one of the important functions of active mesenchyme for maintaining homeostasis and physical efficiency, trained state and adaptation capacity. The special attention is paid to the cerebral blood flow and the cerebral electrical activity. Screening studies enable to correct functional and metabolic states of dynamic homeostasis and physical efficiency assuring good results in sports. The interpretation of obtained information was made relying on theoretical and conceptual propositions of A.K. Guyton, Daniel J. Amen, K. Wasserman.
