1. A method of evaluating muscular physiological parameters of an athlete using a test, comprising:
- fastening a removable and electrically autonomous measurement device to a weight of known mass, said measurement device comprising a three-axis accelerometer;
having said athlete move said measurement device and the weight during said test;
converting a sequence of accelerations along three axes, delivered by said three-axis accelerometer, into a sequence of successive accelerations along a direction of a movement of the weight;
determining the sequence of successive accelerations of said weight during said test;
decomposing the movement into key phases so as to determine the start and end of a key phase and calculate a maximum power during a predetermined key phase;
determining based on the calculated maximum power an optimum weight with which the athlete must train to maximize power deployed during an exercise;
automatically determining at least one key instant or key phase of the test from said sequence of accelerations based on a priori knowledge of a form of at least one portion of said sequence of accelerations;
determining at least one quantity representative of said muscular physiological parameters in said at least one key instant or during said key phase based on said priori knowledge of a form of at least one portion of said sequence of accelerations; and
immediately at the end of said test, indicating the at least one quantity representative of said muscular physiological parameters on a display of the device.
