title: [The relationship between pre-exertional biochemical changes metabolic features during muscular activity].
abstract: Metabolic changes during intense muscular activity and the work efficiency depend on the prestart biochemical changes. Excessiveness of these changes or, particularly, their absence decrease the work capacity. Character of the prestart reaction depends on the grade of adaptation of the organism to muscular activity; favourable, moderate prestart biochemical changes are characteristic o highly trained sportsmen. Disturbed ATP balance in the working muscles was found not to be always a limiting factor for the work capacity.
