Cardiac Output and its Components Among Young Athletes During Functional Loads

摘要

The aim of the research was in inotropic and chronotropic components revelation, as forming cardiac output, during functional loads among young athletes. 14-16 year-old football players took part in the research (49 people). As a result of the increasing power load there were indices changes of heart pumping ability among football players, which varied depending on the age of the respondents. The used power increasing load at bicycle ergometer can be recommended as a loading test in order to reveal functional and reserve capacities of young football players' heart. It can prove the prevailing influence of inotropic or chronotropic components during cardiac output formation. Functional loads and the age of the respondents influence cardiac output formation in young athletes.
