 note = {本研究は,投球動作中の野球投手の肩関節と肘関節について関節間力と関節モーメントを算出し,ストレートとカーブの投球動作を比較することを目的とした.ストレートの球速は,カーブの球速より有意に速かった.それぞれの被験者のカーブの投球姿勢は,手関節と前腕の運動を除き,ほぼストレートの投球姿勢と同等であった.肩関節の関節間力と関節モーメントは,ストレートが僅かに大きく,肘関節の関節間力は,カーブが僅かに大きかった., This study aimed to compare fastball and curveball pitches according to the resultant forces and moments of the shoulder and the elbow joints. We used four rigid body models in a kinetic analysis of the upper-body, and estimated the resultant joint forces and moments of the wrist, elbow and shoulder, using the inverse dynamics technique. Fastball pitching speeds were significantly faster than those for curveballs, for all subjects. The movement of the hand and forearm between fastball and curveball are almost similar without the movement of hand and forearm. The force and moment of the shoulder during fastball pitch are larger than the curveball pitch slightly. The share forces of the elbow during curveball pitch are larger than the fastball pitch slightly., 原著(Original investigation), application/pdf},
