Illustration of the center of mass (CoM) resultant speed during the 5-m shuttle run test (A, Top panel) used to compute average and maximal running speed, as well as turning speed (defined during the gray shaded area). In (B) (bottom panel) the use of anterior-posterior (AP) foot sensor acceleration and AP foot speed to define peak AP foot speed and subsequent foot acceleration.
