Dynamics of morpho-functional indices of 10-13 years old boys under the infl uence of different types of outdoor recreational activities
He paper scrutinizes development of morpho-functional indices in boys engaged in different types of outdoor activities such as hiking, cycling and canoeing, as well as the boys, who didn't take part in sport sections. The study involved eighteen 10-13 years old boys in each group. It was found that the training loads don't influence the indices of physical development that change in accordance with the development of child's body unlike the indices of the functional system. The most substantial influence of outdoor activity was detected on the indices of the cardiovascular and respiratory systems in the group of boys engaged in cycling, and the least in the group engaging in fresh water activities.
