The human fatigue under static and dynamic physical activity And adaptation mechanisms

Abstract

This review focuses on spinal and central mechanisms of fatigue associated with the implementation of adaptation programs. The morpho-functional correlations of the moto-neurons activity of the spinal cord, the activities of the functional systems of the human body, neurotransmitter systems, serotonergic, dopaminergic and noradrenergic systems in the mechanisms of fatigue were considered. The phases of the process of adaptation to physical loads as well as cumulative training effect were identified. The authors have identified and described the participation of the autonomic nervous system, glucocorticoids and other hormones and mediators in long-term adaptation to physical loads, in the transition from carbohydrate to fat type of energy metabolism. The stages of disadaptation and re-adaptation to physical activities (a manifestation of stress, rate adaptation, cybernetic principles of homeostasis) have been identified and described. The two-circuit system homeostasis: the autonomic (controlling) and myocardial-hemodynamic (controlled) was demonstrated and an hierarchy of control has been defined.

“…Электронный журнал пользование тензодатчиков требует наличие усилителя с высоким коэффициентом усиления. Эти недостатки устранены в приборах на основе фотопреобразователя или оптического датчика [5]. Для регистрации движений используют широкополосные пьезоакселерометрические датчики, имеющие ряд преимуществ:…”
