Notes

Abstract:
Catching is widely acknowledged as being one of the most mentally and physically demanding positions on a baseball/softball team. It is often said that catchers are the slowest players on the team due to “bad knees” from prolonged squatting. Yet, hardly any research can be found on the physical stresses imposed on a catcher’s knees. This study focused on the ground reaction forces (GRF) of the catcher while in his/her pitch reception squat for three different scenarios. The participants were asked to receive 15 pitches (5 pitches in each stance) with each foot on the force plate: a relaxed stance, a ready stance without a throw to second, and a ready stance with a throw to second to quantify the peak and average GRF. From the kinematic and kinetic data, the A/P and M/L sheer and compressive forces imposed on the knee throughout the movement were calculated to quantify the peak and average for knee joint forces. Additionally, the stresses were analyzed to see if any one position or movement caused an increase in the forces. Finally, the valgus knee angle for the landing leg at maximum knee flexion during the landing was calculated to quantify the peak and average valgus angle for the knee’s valgus angle motion. No significant differences were found in the GRF or knee forces between the three stance scenarios.
