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. …

Gender Differences In Lower Limb Frontal Plane Kinematics During Landing, Gerwyn Hughes, James Watkins, Nick Owen
Kinesiology (Formerly Exercise and Sport Science)
The study aimed to investigate gender differences in knee valgus angle and interknee and inter-ankle distances in university volleyball players when performing opposed block jump landings. Six female and six male university volleyball players performed three dynamic trials each where subjects were instructed to jump up and block a volleyball suspended above a net set at the height of a standard volleyball net as it was spiked against them by an opposing player. Knee valgus/varus, interknee distance and inter-ankle distance (absolute and relative to height) were determined during landing using 3D motion analysis. Females displayed significantly greater maximum valgus angle …
