Title
(EN) A METHOD AND DEVICE FOR RETRIEVING BIOMECHANICAL PARAMETERS OF A STRIDE
(FR) PROCÉDÉ ET DISPOSITIF DE RÉCUPÉRATION DE PARAMÈTRES BIOMÉCANIQUES D'UNE FOULÉE
Abstract
(EN)
A method for determining biomechanical parameters of the stride of a runner, using an accelerometer device on the wrist, on the upper arm, on the head or on the shoe, comprising the steps of measuring an initial sequence of acceleration data in at least the vertical direction using said accelerometer device; 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 masse; attenuating said frequency component, so as to determine a modified sequence of acceleration data; determining said biomechanical parameters from said modified sequence of acceleration data.
(FR)
L'invention concerne un procédé de détermination de paramètres biomécaniques de la foulée d'un coureur, à l'aide d'un dispositif d’accéléromètre sur le poignet, sur le haut du bras, sur la tête ou sur la chaussure, comprenant les étapes consistant à mesurer une séquence initiale de données d'accélération dans au moins la direction verticale à l'aide dudit dispositif d’accéléromètre ; identifier dans ladite séquence initiale de données d'accélération au moins une composante de fréquence provoquée par un mouvement relatif du dispositif d'accéléromètre par rapport au centre de gravité du coureur ; atténuer ladite composante de fréquence, de manière à déterminer une séquence modifiée de données d'accélération ; déterminer lesdits paramètres biomécaniques à partir de ladite séquence modifiée de données d'accélération.
