Effect Of Tilted Surfaces On Ankle Kinematics And Emg Activities In Landing, Divya Bhaskaran Aug 2010

Effect Of Tilted Surfaces On Ankle Kinematics And Emg Activities In Landing, Divya Bhaskaran

Masters Theses

The purpose of this study was to examine the effects of landing on a combined inverted and plantarflexed surface on the ankle kinematics and electromyographic (EMG) activities of the medial gastrocnemius (MG), peroneal longus (PL) and anterior tibialis muscles (TA). Twelve recreational athletes performed five drop landings from an overhead bar of 30 cm height on to each of these surfaces: a flat surface, a 25° inversion surface (inverted), and a combined surface (combined) of 25° inversion and 25° plantarflexion. The three dimensional kinematic variables and integrated EMG (IEMG) of the three muscles were assessed using one-way repeated measures analysis ...
