Abstract
A method and device determine biomechanical parameters of a runner from an accelerometer worn off-torso on a wrist, upper arm, head, or shoe. Acceleration including a vertical component is acquired and cadence is determined from the initial sequence. At least one frequency component caused by relative motion of the device with respect to the runner's center of mass—comprising a fundamental at approximately one-half the cadence and one or more harmonics—is identified. A cadence-locked comb filter, whose notch center frequencies are functions of the cadence and that applies greater attenuation at the one-half-cadence fundamental and its harmonics than at the cadence fundamental, is applied to generate a modified acceleration sequence that approximates center-of-mass vertical acceleration. Biomechanical parameters such as contact time, flight time, stiffness, undulation, and take-off or landing angle are then determined from the modified sequence.
