Abstract

The purpose of this study was to compare the lead shoulder joint dynamics between one-handed and two-handed follow through batting techniques. Seventeen professional baseball players underwent motion analysis while hitting a ball off a tee using one- and two-handed follow through techniques. Linear mixed regression models were used to compare the kinematic and kinetic variables between the two techniques. Shoulder horizontal abduction, elbow flexion, and lateral trunk tilt differed between the follow through types. The shoulder kinetics increased greatly during a one-handed follow through compared to a two-handed follow through, with the horizontal adduction torque increasing 23.3 Nm and the proximal force increasing 117.2 N. A one-handed follow through increases the demands on the shoulder compared to a two-handed follow through.
