Coefficient of Restitution (COR) in Toe and Instep Soccer Kicks
2005
In all soccer kicks, the velocity of the ball after impact is determined by the velocity of
the foot before impact, the effective striking mass of the foot and the coefficient of
restitution (COR) of the impact (Plagenhoef, 1971, Bull Andersen et al., 1999). The COR
in soccer kicking describes the transfer of velocity from the foot to the ball during the
impact phase and is the ratio between the relative velocity (Vball−Vfoot) after impact and
the relative velocity before impact The factors determining the COR are the mechanical
properties of the foot and ball, i.e. stiffness, contact area and contact point. Furthermore,
the COR in two-dimensional analyses is affected by the direction of the path of the foot
before impact and the path of the ball after impact.
