[Role of sport training in improving function of cardiorespiratory system].

In work is shown, that the sports training on endurance is accompanied functional economization of the cardiorespiratory system (CRS) in rest shown in downstroke of specific sizes of consumption of oxygenium, pulmonary ventilation and central hemodynamics, transport of oxygenium by the blood. The ways of adaptation of CRS and augmentation of its potential during long-term training of the juvenile sportsmen should be focused on creation of optimum conditions for formation gain physical loads of the and mobilization characteristics of functional reactions directed on delivery of oxygenium to working bodies, avoiding an excavation of the tendency of "accustoming" to a disadvantage of oxygenium and excess of products of an exchange.
