Quizplus · Accepted Answer

The acceleration phase of pitching begins when the pitching shoulder reaches maximum lateral rotation. This is when the arm is fully extended and the hand is behind the body, providing maximum stretch to the muscles involved in the pitch. The front foot contact and back foot contact are important parts of the pitching motion, but they do not specifically mark the beginning of the acceleration phase. The ball release from the hand occurs during the acceleration phase, after the shoulder has reached maximum rotation.
