Abstract
Introduction:
This study implemented a 8-week intervention using coach-deveoped games aimed at correcting the flexible flat feet in children aged 6 to 7. To assess the effectiveness of this program, kinematic and kinetic differences in single-leg drop jump landings were analyzed before and after the intervention. The research was guided by two key hypotheses: (1) the 8-week coach-deveoped game intervention would lead to improved performance in single-leg drop jump landings, and (2) the intervention would enhance the efficiency of children's movements during single-leg drop jump landings.
Methods:
24 Children aged 6 to 7 from three kids club in Hamedan City were recruited for the study. The participants were randomly assigned to either a control group (CG) or an experimental group (EG), with each group comprising 12 children. Baseline drop jump landing data were collected using the APEX motion capture system (Bonyan Sanat Novin Inc., Guilan, Iran). Post-intervention drop jump landing data were again recorded using the same system, and analysis of kinematic and kinetic variables was performed using Anybody 7.4 simulation software.
Results:
The experimental group exhibited significant improvements in joint angles and joint torques, accompanied by increased force output from key muscles such as the vastus medialis, vastus lateralis, and gastrocnemius. Additionally, a marked increase in ground reaction force was observed. While the control group also demonstrated some changes in dominant muscle activity, these were less pronounced compared to the experimental group.
Conclusion:
The 8-week exercise game intervention produced notable enhancements in technique and force generation among 6 to 7 year-old preschool children during drop jump landings. This intervention promoted more precise and efficient muscle engagement, resulting in improved force absorption and overall performance in the drop jump landing task.
