Typological Features of Energy Support of Muscular Activity and Physical Education of Boys of 9–10 Years

Abstract: 
The research aim The purpose of the study is to identify typological characteristics of the energy supply of muscle activity of boys of 9–10 years old on the basis of cluster analysis. Research methodology. The study involved practically healthy boys (n = 176) 9–10 years old. We used a set of indicators of skeletal muscle energy supply, physical performance, physical fitness and physical development, and determined body types. Results. Four options for the organization of energy metabolism were revealed, characterized by typical combinations of the levels of development of aerobic, anaerobic glycolytic and anaerobic alactate capabilities of the body with levels of physical performance, physical fitness and physical development. It was found that among boys with a predominance of aerobic metabolism, children with a high level of endurance and leptosomatic physique are often found, and with a predominance of anaerobic metabolism, children with a high level of speed, power, speed and strength abilities and eurysomic physique. Conclusion. The selected options for organizing energy supply of skeletal muscles must be taken into account in the process of physical education, health and sports training for boys of 9–10 years old.
