Measurement of Upper and Lower Body Strength and its Relationship to Underhand Pitching Speed

This study investigated the possible relationship for legs, arms, shoulders, and grip strength with underhand throwing speed. 40 female subjects had their legs, arms, and shoulder strength measured using a multipurpose exercise machine for assessing resistive force. Grip strength was measured using a handgrip dynamometer. Underhand throwing speed was measured with a radar gun. Regression analysis indicated a relationship (p < or = .05) between strength of the arms and underhand pitching speed. No significant relationships were found for legs, shoulders, and grip strength, and underhand pitching speed.
