<p>There are ball control skills in soccer; dribbling, kick, heading, etc.. Trapping, in particular inside trapping, is also one of the important and often-used skills in soccer. In spite of important skill, few reports are available on trapping ball so far. Asai (1981) has suggested that trapping is regarded as a form of the collision of the ball against the foot, and the velocity of ball just after impact is depended on the reduced mass of leg and the relative velocity of the foot and the ball just before impact. Therefore the ill-effect of miss-judgment of the foot velocity may be reduced in trapping when the reduced mass of leg decreases. However, the relationship between the reduced mass of leg and performance level on trapping has not been clarified. The purpose of this research was to explore the performance level on trapping involved in the reduced mass of leg of High-Performance group (HP) by comparison with Low-Performance group (LP). There is a significant difference between HP and LP on trials which ball velocity just before impact was not less than 8.00 m/s. This result implicated the possibility players who the reduced mass of leg is lower can trap high speed ball.</p>
