PCT No. PCT/FI95/00713 Sec. 371 Date Oct. 15, 1996 Sec. 102(e) Date Oct. 15, 1996 PCT Filed Dec. 28, 1995 PCT Pub. No. WO96/20640 PCT Pub. Date Jul. 11, 1996The present invention relates to a method and an apparatus for determining exertion levels in fitness or athletic training and for determining the stress caused by training. According to the invention, the ECG signal of a person and the timing moment of at least one waveform of the ECG signal, for instance the QRS complex, are measured by means of a heartbeat rate monitor during a training period. The heartbeat rate is calculated on the basis of corresponding ECG signal waveform distances, and a value proportional to the magnitude of the heartbeat rate variation or to that of a total or partial power of a spectrum derived from the heartbeat rate is provided by means of a mathematical function. Those exertion levels of the person which are essential as regards to training period or the stress caused by the training in relation to the exertion levels are determined on the basis of the heartbeat rate variation.
