Compare sequence of joint motion and muscle electromyography between low drive and high drive soccer instep kick

Abstract
The purpose of this study was to examine the difference between two types of

the soccer instep kick in temporal sequence of motion and muscle

electromyography, during forward swing phase of the kick. Ten elite soccer

players, volunteered as subjects in the study. To culculate the kinematics data,

we used DLT method with two video camera that filmed five markers fixed on

anatomical points of lower body, at 240 fpm. Moreover the electromyography of

rectus femoris, vastus medialis and tibialis anterior were estimated. Kinematic

data from ten players was extracted using image processing toolbox of

MATLAB software. Using these results, we compared sequences of joint motion

and progression of activation muscle in low drive and high drive kick. The

results indicate that there was a difference in ranks of muscle activation

between two kick, but there were no difference in muscles activation time and

sequence of joint motion between low drive and high drive kick. Furthermore

both kicks have a similar proximal-distal pattern and interaction in muscles

contraction and joints motion
