Introduction: The development of motor skills and basic skills in childhood and adolescence and subsequently adolescence and adulthood affect the growth and development of all aspects of development. The aim of this study was to evaluate the effect of dynamic yard on motor development of children aged 8 to 12 years.
Methods: The present study was quasi-experimental with pretest and posttest design with control group. 30 healthy 8 to 11 year old male students who were studying in Kermanshah in the academic year of 1998-99 were selected voluntarily and randomly divided into two groups of control and experimental. First, pre-tests were performed for both groups. The third edition of Ulrich (2016) was used to assess motor skills. The experimental group participated in the standard training program for 8 weeks and 5 days per week, and the control group performed only daily activities. At the end of the intervention, post-test was performed for both groups. Data were analyzed using analysis of covariance at the error level of 0.05 with SPSS-19 software.
Results: The results of covariance analysis showed a significant difference between the two groups in the post-test of large motor skills and the experimental group performed better than the control group in all variables.
Conclusion: It seems that in healthy 8 to 12 year old boys, using the dynamic yard program can significantly improve their motor development.
