Impact of an isometric or eccentric hip extension exercise intervention on hamstring strength, architecture, and morphology: a randomised intervention trial

Abstract

Introduction: Hamstring strain injury (HSI) is the leading cause of time lost from competition in running-based sports. Following return to sport, individuals with previous HSI often have persistent deficits in hamstring muscle strength, architecture and morphology. Considerable research effort has gone into identifying ways to address these variables, as they have been associated with future HSI risk. Eccentric knee flexion exercises have been shown to modify these variables, although implementation of these interventions in injury prevention programs is not widespread.
