University of Idaho researcher Dr. Craig McGowan used a ProCapture motion capture system to record the hopping movements of this desert kangaroo rat. Dr. McGowan then used ProAnalyst motion analysis software to track several points on the body. A feature line configured with dynamic 3-point angle measurements displays the range of motion in the animal's lower leg. This analysis of the animal's locomotion combined with data from force plates sheds new light on acceleration biomechanics in bipedal hoppers.
