Comparative analysis of the dynamics of electromyographic indicators in persons with different physical preparation in intensive work

The work examines the functional response of the neuromuscular apparatus to a load power of 160 W on a bicycle ergometer at a pedal rotation speed of 7 km / h in individuals who do not have sports training in comparison with amateur athletes. As a research method, electromyography with the analysis of indicators in the dynamics of the load is proposed. It is concluded that this type of load for the persons who are engaged in physical activities means the exercise of submaximal anaerobic intensity, with a refusal to work, mainly due to the peripheral neuromuscular apparatus disturbance, depletion of glycogen in glycolytic fibers. For amateur athletes such type of load is a work of great intensity, the leading factors of fatigue in which are connected with vegetative supply systems and oxygen deprivation of the organism, disturbance in homeostasis.
