Impact of training in sports games and cyclic sports events on muscules and cardiovascular system of 11-14 years old boys

The aim – to determine the sport games and cyclical sports impact on the features of the dynamics in functional parameters of the muscles and cardiovascular systems in boys of the age groups of 11–14 years old. The contingent of this study was 257 boys aged 11–14 years who were divided into three groups: non-athletes (n=85), cyclical sport athletes (n=89) and sport games players (n=83). Were assessed their muscle strength (calf extensors and flexors, and forearm extensors and flexors) and cardiovascular (heart rate) indices. Were found that sport games training sessions are an important external factor, affecting the functional parameters of accelerated changes in cardiovascular system (CS) of the 11–13 years old age groups. The determinant influence of endogenous factors on child’s growth and development particularly increase at the age of 13–14 years, resulting significant changes in CS indices improvement and non-athletes children for the following characteristics almost equal to peers engaged in sports. The improvement of muscle capacity indices depend on the nature of physical load: muscle strength indices more increased in cyclical sports group.
