Confirmatory Factor Analysis as a Biomechanical Tool: A Novel Approach to Investigating Different Fatigue Aspects in Baseball Pitching

BACKGROUND: Rising UCL injury rates at both amateur and professional levels have been linked to fatigue in baseball pitchers. Repeated pitching has been associated with changes to kinematics, kinetics, and perceived fatigue, but no statistical model exists which incorporates all the most common aspects of fatigue into one framework. Confirmatory...
