Mechanisms of formation the training effects in athletes with application of swimmer’s snorkel devise during the aerobic loads

Abstract

In order to determine the peculiarities of the reaction of the cardiorespiratory system of athletes during the application of swimmer’s snorkel, the research of indicators of activity of the cardiorespiratory system was performed. It was found that the use of such devices, both in a state of relative rest and in conditions of cyclic loading of aerobic nature, is an influential additional factor in increasing the capabilities of the cardiorespiratory system of athletes. The basic functional effects of the use of such devices are established: early activation of the expiratory muscles, reduction of the gradients of concentration of O2 and СО2.
