ABSTRACT
In interceptive skills the importance of kinematic constraints, in particular the timing, has been frequently emphasized. However dynamic constraints should also play an important role. Little evidence has been given so far on the role of an object's dynamic such as its kinetic energy (Li & Laurent, 1995) and momentum (Stoff regen, Henderson & Sasaki, 1995). Tberefore, the aim ofthis study was to investigate to what extent the variations of the momentum of an approaching object affect an interceptive action. To produce a performance independent from the object's momentum, e.g., knocking it out of the trajectory, actors could increase movement velocity. It is hypothesized that increasing the momentum of the object to hit would lead to an increase in the maximum velocity ofthe actor's movement.
