Abstract:
A method for determining exertion levels of a person engaged in at least one of fitness and athletic training by means of heartbeat rate measurement during a predetermined training period, wherein the person is subjected to increasing exertion during the training period, said method comprising the steps of:(a) measuring, by means of a heartbeat rate monitor, an ECG signal of the person and a timing moment of at least one waveform of the ECG signal during the training period;(b) calculating heartbeat rate via corresponding ECG signal waveform distances to provide a heartbeat rate signal;(c) subsequent to step (b) and prior to step (d), removing slow processes from said heartbeat rate signal;(d) providing a proportional value which is proportional to at least one of:magnitude of the heartbeat rate variation;total power of a spectrum derived from the heartbeat rate; andpartial power of a spectrum derived from the heartbeat rate by means of a mathematical function; and(e) registering the proportional values during the training period as a time function and determining at least those exertion levels of the person which are essential as regards to the training period concerned on the basis of the proportional values.
