Method and device for assessing muscular capacities of athletes using short tests

摘要

Device (1) for measuring muscular capacity, comprising:
removable fastening means (12) for fastening the device to the athlete or to the moved weight (3; 2);autonomous electrical power supply means (15);a display (11);a three-axis accelerometer (14) for delivering a sequence of accelerations (a(t)) along the axis of movement of the weight, said sequence comprising at least 100 measurements per second over a duration between 1 and 10 seconds; anddata processing means (16) for determining, at the end of the test, on the basis of said sequence of accelerations, at least one quantity representative of the muscular capacity of the athlete and for displaying this quantity on said display (11).

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.
