INTEGRATED PORTABLE DEVICE AND METHOD USING AN ACCELEROMETER TO ANALYSE BIOMECHANICAL PARAMETERS OF THE STRIDE

摘要

Method using an accelerometer (17) for analyzing the biomechanical parameters of the stride of a racing runner, comprising: a) attaching a device (1) on the runner stem, near its center of gravity, said device being electrically autonomous and having a triaxial accelerometer (17), a chronograph (16), a digital processor (19); b) an acceleration data sequence according to at least the vertical direction (av) is measured by said accelerometer as the rider travels a distance (D) on a running route; c) during or at the end of the race, the biomechanical parameters of the stride is calculated by said processor based on said acceleration data, said parameters including stiffness, calculated based on a force of support maximum (Fmax) and lowering (a) of said center of gravity (CG), and / or a maximum bearing force (Fmax).
