This paper postulates that overuse injury in sport is a biomechanical event resulting from the mechanical fatigue of biological tissue. A theoretical foundation and operational framework necessary to model overuse injury as a mechanical fatigue phenomenon is introduced. Adopting this framework may provide a more mechanistic understanding of overuse injury and inform training and preventive strategies to reduce their occurrence.

This article explores the hypothesis that overuse injuries in sport are associated with a mechanical fatigue process.
