High joint forces and torques are associated with injury risk in baseball pitching. Energy flow (EF) analyses have provided valuable information on how segment and joint powers influence the pitching motion but have not been used to investigate EF influence on elbow torque. The purpose of this study was to determine the relationship of pelvis EF and ground reaction force (GRF) with elbow valgus torque in a sample of high school and collegiate baseball pitchers using regularized regression and statistical parametric mapping. A set of 14 GRF and EF variables were found to be predictors of maximum elbow valgus torque. Both groups differed in pitch velocity and elbow torque but exhibited similar patterns of energy generation and transfer at the stride hip and L5S1 joints. These findings could translate to lower body strategies to reduce the injury risk of high school and collegiate pitchers.
