Lower Limb Coordination And Stiffness During Landing From Volleyball Block Jumps, Gerwyn Hughes, James Watkins

Kinesiology (Formerly Exercise and Sport Science)

The aim of the study was to investigate lower limb coordination and stiffness in five male and five female university volleyball players performing block jump landings. Coordination was assessed using angle – angle plots of the hip – knee, knee – ankle and hip – ankle joint couplings and discrete relative phase (DRP) of right – left joint couplings (i.e. left knee coupled with right knee). Leg stiffness was calculated as the ratio of the change in vertical ground reaction force (GRF) to the change in vertical displacement of the centre of gravity between ground contact and maximum vertical GRF. …
