Abstract
The functional status of the organism is a cluster of aerobic, cardiorespiratory and cardiovascular ability in co-operation with the muscular ability ensuring physiological activity of myocard and muscles in the form of regular dynamic and static active movement. Nowadays is observed an increasing lack of physical activity in the pediatric population, which is reflected in the increasing number of the civilization diseases. The aim of this work was to show the impact of regular dynamic activity on the functional status of the cardiovascular system and fitness in schoolable children (n = 100) using Ruffier’s functional test. The values of the Ruffier index were monitored and compared in groups of girls (n = 25) and boys (n = 25) involved in regular school activity within subject „Physical education“ in comparison with groups of children participating also in regular out-of-school physical activity (girls n = 25, boys n = 25) during 5 months. The most significant result (p < 0.001) was observed in functional status of children involved in both regular and after-school activity after 5 months. Presented work showed the significant impact of regular physical activities on circulatory system and muscular work of schoolable children.
