Discussion of rational rule construction in overhand pass using basic principle of mechanics

Abstract

In the present study, the rule was defined rationally by making clearly the dynamics phenomenon about an overhand pass. An overhand pass in volleyball is important basic skill. However, the difference between overhand pass and catching isn't also defined by a rule book. Then no one tells the difference clearly. There are no ways but a referee judges by the subjectivity. Therefore we advanced a study by the following procedures. At the first, it was described about elastic rebound of a ball and phenomenon of "volley ball" was made clear. At the second, we defined which overhand pass is elastic rebound using Muscle-tendon complex. At the third, it was evaluated by running a motion analysis. As a result, it was recognized that the motion analysis is equal to the motion of an overhand pass. Finally, we defined about overhand pass rationally using above mentioned results.
