This study investigated the effects of precision and concentration games on the development of fundamental motor skills and competence in children aged 7 to 10 years. Using a quasi-experimental design with pre-test and post-test measures and a control group, the research involved 30 children from a primary school in Isfahan, selected through cluster random sampling. The intervention included specialized exercises focusing on fundamental movements, motor competence, and precision/concentration games during school sports periods. The results showed that precision and concentration games did not significantly increase overall motor competence scores in the post-test phase (p<0.05, F=0.132). However, there were significant improvements in specific skills, such as throwing a tennis ball with the right hand, highlighting a notable difference (p>0.05, F=0.587). In contrast, no significant differences were found in throwing performance with the left hand. Additionally, these games positively impacted fundamental motor skills, particularly in static balance and running. Overall, while precision and concentration games may not enhance overall motor competence significantly, they effectively contribute to the development of specific motor skills, enhancing certain aspects of motor performance in children aged 7 to 10. These findings suggest that integrating targeted precision and concentration activities into physical education programs can support and foster children's motor skill development.
