Abstract

In the present work physical condition was controlled by cardiological investigations. With waterpolo players, time results of a 6x30 m swimming test and results of the consecutive heart rate restitution were summarized to one index. During the competitive period, better results of the swimming test and impaired results of the cardiac restitution were observed. According to the age-dependent examinations, waterpolo players reach their best condition at their 22nd-23rd years of age, and they can preserve it until the 30th year. Echocardiographic measurements indicate that cardiac measures develop until the 19th-20th years of the athletes, from the 20th till the 30th years only functional indices change, the morphological parameters do not. The mainly parasympathetically controlled resting heart rate and systolic quotient (QS"/QT) do correlate with the relative aerobic power in young healthy men, while the only sympathetically regulated isovolumetric contraction phase and the PEP/LVET quotient do not, they give informations only about the actual physical condition.
