<p>The method involves measuring instantaneous accelerations of a runner, in frontal, lateral and vertical directions, by using three dimensional accelerometers (10) placed at the proximity of a center of gravity of the runner. An information is obtained which represents a runner`s mean frontal velocity measured by a portable device comprising the accelerometers. An index is calculated which is represented as a ratio between a function of instantaneous accelerations of vertical, lateral and frontal directions and a function of frontal velocity. Information representing the index is produced. An independent claim is also included for a device for determination of an index of an effectiveness or ineffectiveness of stride.</p> |
