An accelerometer analyzing biomechanical parameters of the stride of a runner, including: fastening a device on the torso of the runner that is electrically self-sufficient and includes a triaxial accelerometer, chronograph, digital processor and display; measuring a sequence of acceleration data in at least the vertical direction using the accelerometer, while the runner runs a certain distance along a running course; during or at the end of the course, having the processor calculate the biomechanical parameters of the stride, including the lowering of the center of gravity and/or the elevation of the center of gravity and/or the sum of the lowering and of the elevation of the center of gravity and/or the vertical mechanical work of the center of gravity of the runner, on the basis of the acceleration data, of the distance and of a period of time measured by the chronograph; and displaying the parameters on the display. |
