Biomechanical differences in the muscle activation pattern of drop landing from a 60 cm-high platform between flat foot and normal participants on sand and rigid surfaces

The present study compared the biomechanical differences in the muscle activation pattern of the lower extremity of drop landing from 60 cm-high platform between Flat Foot and Normal participants on sand and rigid surface. Eight male A1 athletes with flatfoot and four male A1 athletes with normal foot voluntarily participated in the project. The Qualisys Motion Capture system and electromyography were used to analyses the lower extremity muscle activation pattern data. The Max and Mean EMG findings revealed that there was no significant difference on the muscle activation pattern of the lower extremity between the flatfoot group and the normal group. Therefore, it can be concluded that flat-footed athletes may not be at a disadvantage with foot deformity when performing landing.
