ABSTRACT:
A method of assessing performance potential of a quadruped by determining the timing of successive making and breaking of ground contact by the legs during the stride and the swing time of a leg of the quadruped while in a high-speed gait. Overlap time of the legs, that is, the time that more than one leg is on the ground at one time, as a function of the forward speed of the quadruped and the time required to complete the stride are derived. The total airborne time is determined and related to the stance, swing, and overlap of the stride time. Performance is assessed in terms of swing time, stance time, overlap time, airborne time and combinations thereof. A method is disclosed of relating measurements of the gait taken at an arbitrary speed to a standard reference speed for purposes of comparing different individuals.
