Abstract

Females involved in sport are more susceptible to injury during landing than their male counterparts, which may partially be attributed to their ability to attenuate the excessive loads experienced. This investigation aimed to evaluate a customised simulation model developed to replicate the kinetics of female impact landings. The model incorporated a rigid foot and shank, thigh and upper body segments, which each comprised wobbling and rigid masses. Model accuracy was defined by quantifying the differences between simulated and actual landings. The model reproduced ground reaction force profiles to 16% of the measured range and peak vertical force times to 8ms. The limitations of using a rigid foot were addressed and future applications of the model for gaining insight into load attenuation strategies used by females in landing were discussed.
