Claim 16:
17. An accelerometer device for determining biomechanical parameters of the stride of a runner with a high accuracy, comprising:
means for fastening the device to one wrist, to one upper arm, to the head or to one shoe;
an accelerometer for measuring an initial sequence of acceleration data in at least the vertical direction, said initial sequence of acceleration data depending on the motion of the runner's center of mass, and on extra-motions of the accelerometer device relative to the runner's center of mass;
a processing system containing a processor and a memory containing a program code arranged for:
identifying in said initial sequence of acceleration data at least one frequency component caused by relative motion of the accelerometer device relative to the runner center of mass;
attenuating said frequency component, so as to attenuate the component of acceleration due to said extra motions, so as to determine a modified sequence of acceleration data corresponding to the one that would be measured at the runner's center of mass;
determining said biomechanical parameters of the stride from said modified sequence of acceleration data.
