The purpose of this study was to develop practical recommendations for improving the methodology of applying specialized physical exercises to enhance motor activity in preschool children. The research employed analysis of scientific and methodological literature, pedagogical observation, mathematical-statistical analysis, and a pedagogical experiment. The study was conducted among children aged 5–6 years in several preschool institutions. A system of age-appropriate physical exercises, including movement tasks and action games, was implemented. The results demonstrated a significant improvement in motor activity, physical fitness, and key physical qualities such as coordination, agility, and endurance in the experimental group compared to the control group. Statistically significant changes were observed in selected anthropometric and physiological indicators. The findings confirm that the systematic application of structured physical exercises, combined with interactive activities, effectively enhances motor development and overall physical condition in preschool children, emphasizing the importance of methodologically grounded physical education in early childhood.
