The research objective was to study the effects of hypoventilation breathing on physical working capacity of individuals during exercise to failure on a cycle ergometer. Subject to survey were 13 apparently healthy young males of 18-22 years of age doing physical culture and sports on a regular basis. Each subject was surveyed twice, during the surveus he was asked to perform physical work to failure on a cycle ergometer at the constant pedaling speed of 1 rps. In between the 1st and the 2nd tests, the subjects have been learning hypoventilation breathing (HVB) technique for 30 days. It is shown that, against the background of HVB, there is an enhancement of ventilation and motor hypoxia tolerance. At the same time, there occurs an increase in the sympathetic effects, minute blood volume, tissue oxygen utilization, "economization" of respiration, which in the end leads to a significant improvement of physical working capacity.

Keywords: sports, failure to exercise, voluntary hypoventilation, physical working capacity.
