The development of a simple, semi-analytical parametric model of sprinting, particularly for the 60 m indoor sprint, is described. The overall aim is to produce a tool for studying the influence of a range of physiological and external parameters on the time it takes to complete this event. The basis of the model is the hypothesis that maximum speed is limited by the fact that there is a minimum time for the sprinter's front leg to be rotationally accelerated backwards from its outstretched position to the vertical position at which the foot strikes the ground. This angular acceleration is linked via estimates of the leg's mass and moments of inertia to the linear acceleration of the athlete at the start of the race, allowing a velocity/time diagram to be constructed for the whole motion. The effect of a change to the mass of the shoe is then studied as an example of the model's usefulness.
