QUANTITATIVE ANALYSIS OF SLIDE STEP DELIVERY IN HIGH SCHOOL BASEBALL PITCHERS
Keywords: kinetic chain, motion analysis, pitching delivery styles
AbstractThe purpose of this study was to quantify the kinetics, kinematics, and segmental sequentiallity during the slide step pitching motion in high school baseball pitchers. Eighteen participants [16.2 + 1.6 yrs; 76.9 + 12.2 kg; 178.2 + 7.2 cm] volunteered to participate. Kinematic data describing the kinematics and kinetics during the slide step pitching delivery were collected with an electromagnetic tracking system via the MotionMonitorTM and calculated as per ISB recommendations. Data were described at foot contact, maximum external shoulder rotation, ball release, and maximum internal shoulder rotation during the slide step delivery.
