The purpose of this study was to compare the muscle activation patterns for the Biceps Femoris, Gastrocnemius, Triceps Brachii, Biceps Brachii, Upper Trapezius, Lower Trapezius, shoulder rotation, elbow angular velocity, elbow flexion-extension & pelvis rotation between the curveball and fastball. Participants were current elite baseball pitchers. After the placement of electrodes, Maximal Voluntary Isometric Contractions (MVIC) were completed. Significant differences in elbow flexion-extension, shoulder rotation, and pelvis rotation for the stretch curveball when compared to the stretch fastball were found. The increase in muscle activity and the greater than MVIC values indicate that lower extremity muscles are beneficial in incorporating into the pitching literature and play a role in the dynamic muscle strength needed to complete a pitch from a specific delivery.
