Abstract

Reducing the forced plantar-flexion during impact of kicking is beneficial to kick performance. The aim of the present study was to identify the relationship between three impact characteristics with plantar-flexion; ankle stiffness, impact location and foot speed. By using a mechanical kicking machine to control impact characteristics, three separate data sets for each impact characteristics were created from high-speed-video camera (4,000 Hz). Relationships were determined from 1st, 2nd or 3rd order bivariate regressions. A linear relationship existed for joint stiffness, meaning a players’ strength can reduce plantar-flexion. A 2nd order relationship was identified for impact location and impacting the ball closer to the ankle decreased plantar-flexion. A 3rd order relationship was identified for foot speed and dorsi-flexing at the start of impact reduced plantar-flexion.
