The Effects Of Short Foot Exercise On Ground Reaction Forces During Landing, Connor M. Owen, Daniel Metri, Jacob Mayoral, Andy Arant, Dane Johnson, Robert Dudley, Andrea Du Bois

International Journal of Exercise Science: Conference Proceedings

The foot is a shock absorber which helps attenuate loads during landing activities via pronation. Intrinsic foot muscles help stabilize the arch of the foot and assist in controlling pronation. Excessive pronation during landing may transfer up the kinetic chain, increasing the risk of knee injury. Additionally, increased ground reaction forces (GRF) during landing may increase the risk for an ACL injury. Acute bouts of short foot exercise (SFE) can strengthen IFM, improving foot posture, balance, and energy transfer in dynamic activities, reducing injury risk. PURPOSE: Therefore, this study investigates whether SFE training before jump performance lowers GRF upon landing ...
