For improved training attitude in sports, especially in running, a method and a device (1) are given. It will - By at least one light source (7a, 7b) light (L) in the body tissue (18) of a subject (2) irradiated, the light intensity (I) reflected in the body tissue (18) is measured by means of at least one light sensor (8a, 8b), - derived from the measured light intensity (IM1, IM2) by evaluation means (16, 23) a time-oscillating measured variable (G), - Minima (29) determined in the time course of the measured variable (G) and - By analysis of several temporally successive minima (29) a power level (L) from which the current state of metabolism of the subject (2) is readable, created and displayed. |
