GROUND REACTION FORCES ATTENUATION IN SUPINATED AND PRONATED FOOT DURING SINGLE LEG DROP- LANDING
Keywords: rate of loading, pronated foot, supinated foot
AbstractThe purpose of this study was to compare the GRF attenuation between normal, supinated and pronated foot during single leg drop-landing. 30 healthy male students from kinesiology department participated in this study. Subjects were assigned to three groups by navicular drop test and performed single leg drop-landing on the force plate from the box with height of 30 Cm. peak VGRF and ROL calculated using GRF data. To evaluate differences in peak VGRF and ROL between three groups MANOVA at the P level of 0.05 used. Differences in ROL was significant between three groups (F2, 22=15.553, Wilks’ Lambda = 0.370,) but differences in Peak VGRF was not significant (F2, 22 = 2.632, ). These results suggest that supinated foot is associated with specific lower extremity kinetics. Differences in these parameters may subsequently lead to differences in injury patterns in supinated foot in athletes.
