The influence of heel height on vertical ground reaction force during landing tasks in recreationally active and athletic collegiate females.

Authors:  Lindenberg KM, Carcia CR

Increased vertical ground reaction forces (vGRF) during landing are theorized to increase ACL injury risk in female athletes.  The purpose of this study was to determine if heel height alters vGRFs when landing from a forward hop or drop landing.  The authors concluded that the addition of a 24mm heel lift to the bottom of a sneaker significantly alters peak vGRF upon landing from a unilateral forward hop but not from a jumping maneuver.
