The purposes of this study were to examine the differences in the peak impulses and ground reaction forces (GRF) of the lead and back legs as well as how energy flows (energy absorption, generation, and transfer) in the back hip, front hip, and L5S1 joints during the baseball swing phases between high school and collegiate baseball players. The findings indicate that the mechanical energy flows down the chain from the L5S1 joint to the pelvis into the lead leg during the bat acceleration phase of the swing in both participant groups. It is hoped that these findings may help coaches and athletes understand which kinetic components of the swing improve bat speed. Thus, coaches may develop training strategies to improve bat speed and player performance.
