RESUMEN
Research on studying influence of a rate of muscular training in conditions of additional aerodynamic and flex resistance to breath on a level of physical working capacity, aerobic productivity and a functional condition of system of breath is executed. It is shown, that regular muscular training on a background of use of the dosed out breath with increased aerodynamic and flex resistance to respiratory stream and respiratory movements, first of all. provides essential growth of functionalities of the respiratory muscles expressed in authentic increase of power and speed-power parameters, shortening of time of impellent reaction of respiratory muscles. Improvement of a functional condition of respiratory system, and, in particular, respiratory muscles, caused significant growth of physical working capacity and physical readiness of young sportsmen.
