The purpose of the research is to study the possibilities of increasing the physical strength of an athlete through special exercises. An increase in endurance during physical exertion in relation to strength sports and martial arts is also separately considered. The physiological aspects of the work of human muscles are analyzed, on which the power traction of the muscle and the possibility of prolonged work under load depend. Myofibrils and mitochondria located in muscle fibers are chosen as the main object of the study.
