In modern society, which is characterized by many positive and negative changes, physical and health culture is becoming increasingly important. The need for systematic and quality leisure time from the earliest days stems not only from the changed lifestyle, but also from the fact that in modern living and working conditions are increasingly endangered functions and abilities of the body that can be quickly and efficiently changed by physical and health culture. , develop and improve. The aim of this research is to determine the impact of extracurricular sports activities on the development of motor skills of 4th grade elementary school students. The research was conducted on a sample of N = 40 respondents, divided into two subsamples, group A and group B. 20 students who engage in extracurricular sports activities in addition to teaching physical education and health GR-A and 20 students who do not engage in extracurricular sports activities in addition physical education and health classes GR-B. To assess motor skills, 4 variables were used, of which 2 were variables for flexibility assessment: Forward bend on the bench(MPKKL), Right bend on the bench (MPKDS) and 2 repetitive strength assessment variables: Swedish bench torso lift (MPTSK) and Hinges on the crossbar by undertaking. (MZNPP). Descriptive statistics were used for data processing, and univariate analysis of variance (ANOVA) was used to determine differences. The results of the research showed that additional extracurricular sports activities led to the improvement of motor skills (flexibility and repetitive strength). It was found that there are statistically significant differences between group A and group B in the variables Right bend on the bench (MPKDS), Swedish bench torso lift (MPTSK) and Hinges on the crossbar by undertaking. (MZNPP) for the benefit of group A, ie students who, in addition to teaching physical education and health, engage in extracurricular sports activities. The goal of extracurricular activities is to include as many students as possible, regardless of their abilities, to identify psychomotor gifted students and direct them to sports schools and clubs. Creating a constant need for physical exercise, ie a constant habit of playing sports, such amounts of psychomotor and other life knowledge will be adopted, the value of which will significantly participate in the development of anthropological characteristics of young people and keep them at a high level until late life.
