Introduction: In recent years, alterations in shoes insoles are used as an effective factor on running kinematic and kinetics in order to improve performance. Therefore, the purpose of this study was to explore the effects of using double density spike shoes and regular spike shoes on the ground reaction force components before and after fatigue.
Methods: The present study was quasi-experimental. The statistical sample of the present study included 13 female runners (Age: 20.4±2.4). Based on the availability, two models of Nike shoes (Nike, Nike Zoom Rival, USA) were selected. Participants were asked to use both shoes before and after fatigue protocol while the ground reaction forces were recorded. Two way ANOVA with repeated measure was used for statistical analysis at significant level of 0.05.
Results: The results showed that main effect of the shoe for the initial peak values of the ground reaction force along the vertical axis is statistically significant (P=0.005). Paired-wise comparison revealed lower initial peak values of the ground reaction force along the vertical axis while using double density spike shoes than that regular spike shoes. Also, main effect of fatigue for free moment values was statistically significant (P=0.002).
Conclusion: Double-density shoes decreased the free moment and loading rate values compared with regular running shoes.
