INTEGRATED PORTABLE DEVICE AND METHOD IMPLEMENTING AN ACCELEROMETER FOR ANALYSING BIOMECHANICAL PARAMETERS OF A STRIDE

摘要

The invention relates to a method implementing an accelerometer (17) for analysing biomechanical parameters of the stride of a runner, comprising: fixing a device (1) on the trunk of the runner, said device being electrically autonomous and comprising a triaxial accelerometer (17), a chronograph (16), a digital processor (19) and a display (11); b) using said accelerometer to measure a sequence of data relating to acceleration in at least the vertical direction (av), while the runner runs a certain distance (D) along a running course; c) during or at the end of said course, having the processor calculate the biomechanical parameters of the stride, including the lowering (A) of the centre of gravity and/or the elevation (E) of the centre of gravity and/or the sum of the lowering and the elevation of the centre of gravity and/or the vertical mechanical work of the centre of gravity (CG) of the runner, on the basis of said acceleration data, said distance (D) and a period of time (T) measured by the chronograph (16); and d) displaying said parameters on said display (11).
