Material: in the research 6 years children participated (n=64, boys - n=36, girls- n=28). Indicators of main muscular groups’ static endurance were studied. Results: we determined comparative topography of 13 muscular groups’ static endurance and substantial sex dimorphism was found. In 9 muscular groups the boys advantage was 11.7 - 50.2% (р < 0.05 ÷ 0.01). The level and correlation of muscles-antagonists’ static endurance from the point of evolutionary and ontogeny development of muscular-skeletal apparatus were substantiated. At the end of semester we found significant (р < 0.001) reduction of static endurance indicators as well as the fact that torso muscles were the most sensitive to influence of learning work’s static component. The level of static endurance weakening, under which syndrome of static over-tension appears, was determined. Conclusions: the research results permit to balance the volumes of learning load at initial stage of school work. Organizational-methodic principles of learning and physical education system for children shall be oriented on overcoming muscular-skeletal apparatus’s dysfunctions.}, number={4}, journal={Pedagogics, psychology, medical-biological problems of physical training and sports}, author={Bondarenko, S.V.}, year={2017}, month={Aug.}, pages={157–162} }
