CHRONOTROPIC HEART ACTION PROPERTIES IN TEENAGE MIDDLE OB RESIDENTS UNDER CYCLE ERGOMETER TEST

Abstract

A heart rate variation analysis in male and female teenage Middle Ob residents under rated exercise increase has been performed. 96 teenage male and female Middle Ob residents have been surveyed. The ECGs and HRs have been registered with a 12-channel ECG recorder (cycle ergometer mode) prior to exercise, at 50 W, 100 W, 150 W, 200 W loads, in the recovery period, and after the test. It has been found that the chronotropic reaction to graduated exercise is higher in females than in males at 50 W, 100 W. The 150 W exercise has been completed by 28 % of the girls and 85 % of the boys. It has also been recorded that exercise tolerance in boys is higher than in girls; also it is higher in teenagers who exercise regularly.
