A scaled OpenSim model was used to assess the variability and changes in muscle loads across multiple strides and at different running speeds (2-8 m·s-1). Peak biceps femoris muscle fibre force, length, velocity and power occurred during the late swing phase of running and became more variable above 6 m·s-1. With each increase in running speed from 2-8 m·s-1, peak force occurred earlier in the swing, at longer muscle lengths and became less variable in its timing.Changes in variability can create a greater risk of injury and exploring these trends further may provide additional insight into hamstring strain injuries.
