The dynamics of functionalities of respiratory muscles of sportsmen under influence increased loadings on breath

It is shown, that regular use of the dosed out breath with increased aerodynamic and flexible resistance during muscular loadings promotes substantial growth of power and speed-power abilities of respiratory muscles. Thus authentic shortening time of impellent reaction as for inspiratory, and especially for expiratory muscles is observed. Increase of functionalities of respiratory muscles, probably, is the reason of authentic increase of a level of physical working capacity of sportsmen.
