Notes. According to Plisky [33] the arm that is being measured is the stance arm (i.e., T arm reach means that the NT arm is measured). Values are mean ± values standard deviations. CS Composite score; IF Inferolateral; M Male; MED Medial; NT Non-throwing arm; F Female; SL Superolateral; T Throwing arm
