Abstract

The aim of this study was to determine the impact of sport games and cyclical sports on the features of cardiovascular reactions to exercising and to the muscular strength in cohorts of boys aged 11–14. The participants of the study were 257 boys aged 11–14: non-athletes, cyclical sport athletes and sport games players. Their muscle strength and cardiovascular indices were registered and taken for analysis. We have found that training sessions of sport games are an important external factor affecting the functional parameters of accelerated changes in the cardiovascular system (CS) of the 11–13-year age groups. The influence of endogenous factors on a child’s growth and development notably increases at the age of 13–14 years, resulting in a significant improvement of CS indices, and non-athlete children by these following characteristics almost equal their peers engaged in sports. The improvement of muscular capacity indices depends on the nature of physical load: muscle strength indices increased more significantly in the cyclical sports group.
