Typological features of energy supply of muscle activity in 9-10 year-old children

Aim. The purpose of the study is to identify typological features of energy supply of muscle activity in 9-10 year-old children by means of cluster analysis. Materials and methods. The study involved apparently healthy girls (n = 201) and boys (n = 176) ages 9-10 years. A set of indicators of energy supply, physical performance, physical fitness and physical development was used for the study, as well as body types were determined. Results. Analysis of differences between groups showed that 9-10 year-old boys demonstrated higher values (p
