[Effect of a bicycle ergometer load on the state of the sympathetic-adrenal system and hemodynamic indices in highly trained athletes].

The effect of the bicycle-ergometry load on the condition of the sympatheticoadrenal system, the values of cardio- and hemodynamics, and some biochemical indices of metabolism was studied in 36 athletes. Study of the activity of the sympatheticoadrenal system in a complex with the functional and biochemical values during bicyle-ergometry load made it possible to appraise the condition of the adaptive reactions of the athlete's organism during muscular activity and to diagnose in time and prevent a state of physical overstrain.
