Hamstrings Are Stretched More and Faster during Accelerative Running Compared to Speed-Matched Constant-Speed Running.

ABSTRACT:

Objective

Hamstring injuries are common in field-based sports and reinjury rates are high. Recent evidence suggests that hamstring injuries often occur during accelerative running, but investigations of hamstring mechanics have primarily considered constant-speed running. Thus, our objective was to compare hamstring lengths and velocities between accelerative running and constant-speed running.

Methods

We recorded videos of 10 participants during six accelerative running trials and six constant-speed running trials. We used OpenCap to estimate body segment kinematics and a three-dimensional musculoskeletal model to compute peak length and step-average lengthening velocity of the biceps femoris (long head) muscle-tendon unit. We compared running conditions using linear mixed
