The Peak Vertical Ground Reaction Forces Differences between Foot Types During Landing
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 4, Issue 10
Abstract
The aim of this study was to compare the peak Vertical Ground Reaction Forces (VGRF) between supinated, pronated, and normal feet during single leg drop landing. Thirty healthy male students from physical education & sport sciences department [mass 74.32 ± 6.50 kg, height 176.20 ± 5.43 cm, age 23 ± 2 years] participated in this study and assigned to one of three groups by navicular drop test (10 per groups) [pronated (10mm), neutral (5-9mm), or supinated (4mm)]. Participants performed single leg drop-landing on the force plate from the box with height of 0.30 m. Peak VGRF were calculated using GRF data. There were no significant differences in Peak VGRF between three groups (F2, 27 = 0.510, P >0.05). These results suggest that foot types are not associated with specific lower extremity kinetics. Not differences in these parameters may be resulting of existence another factors influencing VGRF.
