In low tolerance exercise during respiratory execution there were a decrease saturation changes heart rate. are based different physiological processes human body that create load tolerance: oxygen supply tissues.Conclusions. All selected could be executed anywhere short period time. They easy perform do not cause emotional reactions used assessment. results obtained complementary can recommended use complex when examining health screening types.
