A new perspective on when the hamstring is at greatest risk during high speed running

Hamstring strain injuries (HSIs) are the most common and recurrent soft tissue injury in Australian Rules Football (ARF) [1], with only minor reductions in prevalence observed over the past 20 years. While common belief suggests that hamstring injuries are most likely to occur during terminal swing phase, this study showed significant increases in movement variability during early stance phase among those with a history of HSI, thus identifying early stance as a point of increased soft tissue vulnerability.
