PCT No. PCT/FI95/00565 Sec. 371 Date Jun. 23, 1997 Sec. 102(e) Date Jun. 23, 1997 PCT Filed Oct. 11, 1995 PCT Pub. No. WO96/11630 PCT Pub. Date Apr. 25, 1996The invention relates to a method and a device for determining threshold values for a person's energy metabolism. A testee is subjected to a gradually increasing stress in order to obtain the threshold values for his energy metabolism. The pulse rate of the testee is measured during the performance, the pulse shape of an ECG signal caused by the pulse is analyzed in order to determine the timing point of the ECG signal corresponding to each pulsation and in order to determine the intervals between the timing points of success of ECG signals. The respiratory frequency of the testee is calculated on the basis on the variations in the intervals between the timing points of the ECG signals. The respiratory frequency of the testee is calculated as a function of the pulse rate during the performance, where the respiratory volume is estimated on the basis of the degree of the variation in the timing points of the ECG signals, and ventilation is calculated as a function of the pulse rate on the basis of the respiratory frequency calculated during the performance and the estimated respiratory volume. At least one threshold value for the energy metabolism of the testee is determined on the basis of the respiratory frequency or the ventilation and the pulse rate.
