The purpose of current study was to compare the ground reaction forms (GRF) of the stride leg in baseball pitchers using two different pitching stride techniques. Fourteen college pitchers volunteered as participants and made maximum effort pitches on an indoor mound toward a 8 m away target. The ball velocity were measured by a radar gun, the GRF were measured by a forceplate, and the trajectory of pelvis center were measured by a motion analysis system to classify pitcher's strides as tall-and-fall (TF) or dip-and-drive (DD). There were no significant difference between two groups in ball velocity and stride leg GRF during pitching, and the ball velocity were significantly correlated with the vertical GRF of stride leg at ball release in TF group. It suggested that the different pitching technique might be used for different stride types.
