The main goal of this paper is to evaluate the differences in the perception of selected features of the implementation of kinesiology content of exercise in younger school-aged children. For the purposes of analyzing differences in the perception of selected features of the implementation of kinesiology content of exercise for children of younger school age, a survey questionnaire of 26 items was used. Respondents expressed their degree of agreement with each statement on a 5-point Likert scale. The sample is composed of 123 entities, with an average chronological age of 30.30 ± 11.92 years. The results of the research showed that the majority of respondents understand the importance and need for physical activity, although 37.4% of respondents do not engage in any physical activity. The biggest limiting factors/obstacles that affect not engaging in physical/sports activities are the lack of free time and the lack of attractive offers of sports activities near the place of residence. The highest average values of the results were shown by respondents who engage in physical/sports activities at least 3 or more times a week and respondents who are employed in the educational system. The biggest differences in the results were observed in the assessment only and the assessment of parents' interest in extracurricular and extracurricular organizational forms. Research has shown that experience in the educational system and regular physical activity show better results in the understanding and implementation of kinesiology content of exercise in children of younger school age.
