Abstract

Kinematic and kinetic data from a maximal velocity sprint trial resulting in a hamstring strain injury was analysed using a forward dynamics musculoskeletal model solved using direct collocation (OpenSim Moco) to assess muscle fibre states of the bicep femoris long head (BFlh) muscle during the swing phase. During the injury trial, the BFlh showed greater peak fibre lengths, similar peak fibre force, velocity and power, but less negative work compared to submaximal speeds. Accumulation of muscle tissue damage from previous steps and prior submaximal sprints due to the eccentric demand on the muscle could have resulted in the BFlh failing as it no longer had the capacity to withstand load.
