Table 3 Summary of maximal rotation (trunk internal rotation, shoulder internal rotation and forearm pronation) and flexion/extension angular velocity (°/s) parameters (trunk flexion, shoulder flexion, elbow extension and wrist flexion) as well as parameters at ball release (trunk flexion, shoulder internal rotation). Data are means (±SD).
