N. Tsaousidis et V. Zatsiorsky, 2 TYPES OF BALL-EFFECTOR INTERACTION AND THEIR RELATIVE CONTRIBUTION TO SOCCER KICKING, Human movement science, 15(6), 1996, pp. 861-876
The study attempts a closer examination of the ball-foot interaction a
t the instant of soccer kicking using high speed videotaping. This all
ows a detailed biomechanical analysis of the collision. A central ques
tion is whether the ball-foot interaction can be modeled as an elastic
impact, or as a mixture of 'impact-like' and 'throwing-like' patterns
. The findings prove that the theory of conservation of momentum alone
is not adequate for modeling kicking: additional momentum and mechani
cal energy is supplied to the system during the collision phase becaus
e of the muscle work. This is due to the relatively long duration of c
ollision (about 16 ms) and the large ball-foot displacement (about 26.
0 cm). More than 50% of the ball's speed and at least 30% of its kinet
ic energy is imparted to the ball without any contribution of the pote
ntial energy of the ball deformation.
