Abstract
System and method implementing an accelerometer (17) for detecting asymmetries in a movement of a user. The system includes a fastening a device (1) on the torso of the runner, close to his/her center of gravity (CG), the device being electrically self-sufficient and comprising a triaxial accelerometer (17) and a digital processor (19). The accelerometer is used to measure a sequence of acceleration data in at least the vertical direction (av), while the user performs at least one exercise. During or at the end of the exercise, having the processor calculate the biomechanical parameters enabling the detection of at least one asymmetry in a movement of the user, on the basis of the acceleration data.
