Motor Skills in the Structure of Physical Fitness of 7-Year-Old Boys

The purpose of this study was to determine the weight of motor skills in the structure of motor fitness of 7-year-old boys.  Materials and methods. The study participants were 38 7-year-old boys. The children and their parents were informed about all the features of the study and gave their consent to participate in the experiment. The research methods used in the study include analysis of scientific and methodological literature, pedagogical observations, testing of motor fitness, probabilistic approach to assessing the learning process, methods of mathematical statistics.  Results. The level of fitness of the 7-year-old boys is homogeneous by the development of “agility” and “movement coordination”, inhomogeneous – by the development of arm strength and vestibular stability. The 7-year-old boys’ motor fitness is determined by their physical development, the level of general physical fitness and the level of motor skills development. A graphic representation of a two-factor model of testing results shows that analysis identifies two sets of data with high correlation coefficients. The first set includes tests No. 2, 1, 4, and 5, which characterize physical development, agility and endurance; the second – the level of proficiency in exercises No. 14, 13, 12, and the result of test No. 7 “Mixed hang rope pull-ups”. Conclusions. Based on factor analysis, the study found that the level of proficiency in exercises determines the variation of testing results by 28.437%, and the development of motor skills is a priority in the educational process at primary school. The development of “agility” and “movement coordination” ensures the formation of motor skills, and the development of arm strength and vestibular stability is the reserve in training boys aged 7 which will make it possible to increase the effectiveness of the educational process.
