Abstract:
1. A method of monitoring a user's performance during physical exercise, the method comprising: determining, in a user-specific performance monitor device, a propagation variable characterizing the user's propagation on a propagation route; determining, in the user-specific performance monitor device, a gravitational motion variable characterizing the user's motion in the direction of the gravitational field; calculating, in the user-specific performance monitor device, an inclination factor proportional to the inclination of a propagation base in accordance with the propagation variable and the gravitational motion variable, the inclination of the propagation base being positive or negative in accordance with the user's motion with respect to the gravitational field; calculating, in the user-specific performance monitor device, a propagation factor proportional to a propagation efficiency of the user as a function of the inclination factor, the propagation efficiency characterizing the user's ability to move with respect to the inclination of the propagation base; and calculating, in the user-specific performance monitor device, an exertion parameter that characterizes the user's energy consumption along the propagation route based on the propagation variable, the gravitation motion variable and the propagation factor, wherein the user's exertion parameter is calculated by using, when the inclination of the propagation base is negative, a first functional dependence of the exertion parameter on the propagation variable and the gravitational motion variable and, when the inclination of the propagation base is positive, a second functional dependence of the exertion parameter on the propagation variable and the gravitational motion variable, wherein the second functional dependence produces, with at least one value pair of the propagation variable and the gravitational motion variable, an exertion parameter which is different from the exertion parameter produced by the first functional dependence with said value pair.
