Comparative Study of Ground Reaction Forces and Ankle Joint Kinematics in Various Sidestep Angles Following Landing from Soccer Player's Heading

The data set of initial coordinates were obtained via collected static experimental data on the subjects in an anatomically neutral position. Eight infrared cameras (200 Hz, Oxford metric Ltd., Oxford, UK) and an in-ground force plate (1000 Hz, AMTI, Watertown, MA, United States) were used to record the marker trajectories and GRF for the landing and the accelerate startup contact. Vicon Nexus 1.8.6 software was used to synchronously collect ground reaction force data and kinematics data.
