Kinematics of Kicking as a Function of Different Sources of Constraint on Accuracy

Abstract

The kinematics of kicking were investigated using five experienced players at soccer. They were required to kick powerfully balls of two sizes under conditions with defined and undefined targets. High-velocity cameras were used for three-dimensional analysis. Analysis indicated that the defined target condition led to lower movement speeds and shorter movement rimes, while balls' sizes influenced only time after peak velocity.
