Abstract

Background: This study aimed to compare the effects of the Arch-Support insole on the values of Impulse, Vertical Loading Rate, and Free-Moment among handball players with the pronated foot during the jump and landing three-step shot technique.
Methods: This study was quasi-experimental and laboratory. 10 pronated foot and 10 healthy (control group) handball male players were selected as convenience sampling. The test was performed as a pre-test and post-test in two conditions with and without the use of Arch-Support insoles during the jump and landing. Two-way ANOVA test was used for statistical analysis at the significant level (P<0/05).
Results: The inter-group results showed that the vertical loading rate (P=0.032), impulse (P<0.001), and maximum free moment (P=0.013) in two groups, control, and pronated foot during jumping; Also, the vertical loading rate (P=0.001), impulse (P<0.001), and maximum free-moment (P=0.049) in two groups, control, and pronated foot during landing had significant differences. The results of the intra-group test showed that the vertical loading rate (P < 0.001), impulse (P = 0.002), and maximum free-moment (P = 0.027) during jumping; Also, the vertical loading rate (P<0.001), impulse (P=0.001), and maximum free-moment (P=0.043) during landing in the pronated foot group had a significant decrease in the post-test compared to the pre-test.
Conclusion: The use of Arch-Support insoles can prevent possible injuries to the lower limbs by reducing the values of Impulse, Vertical Loading Rate, and Free-Moment.
Keywords: Pronated Foot, Arch Support Insole, FreeMoment, Vertical Loading Rate, Impulse.
