Introduction: Motor skills in children reach to their maximum degree by going through stages of development; but this progress does not happen automatically. Being unable to reach advanced levels of these movements, decreases childhood activities and prevents reaching the ability of specialized movements. The aim of this study was to investigate the impact of badminton skills on compensating fundamental activities for children.Materials and methods: Girls, seven to twelve years old with lagging in movement, were participants of this study. Pretest and posttest were performed at the beginning and end of the study, using Test of Gross Motor Development (TGMD-2) method. The experiment group was trained badminton skills for 12 weeks. The control group took the same training after the tests.Results: There was a significantly higher performance in locomotor skills in the experimental group, compared with the control group which did not participated in any training (P = 0.001). Results were the same with the manipulation skills, indicating the impact of training (P = 0.001)Conclusion: It is necessary to pay attention to compensating motor lag in the early ages, whereas training badminton skills has positive impact on this compensation of fundamental activities in children.
