Patent ID: 8401630

Claim:
A method of determining the training intensity of a person, whereby the heart frequency data of the person is measured, the method comprising: a) recording the time intervals RR i between consecutive heartbeats; b) selecting a sequence of intervals RR through defining a number N of consecutive intervals RR i or determining an observation interval; c) producing a sequence of standardized intervals rr i from the sequence of intervals RR i through mathematical modelling; d) creating points in a Poincaré plot of the standardized intervals rr i from two consecutive standardized intervals rr i and rr i+l ; e) calculating a 95% confidence ellipse for the points of the sequence of standardized intervals rr i in the Poincaré plot, whereby a principal horizontal axis X 0 and a principal vertical axis Y 0 is determined; f) calculating a standard deviation SO L from the orthogonal distances of the points of the sequence of standardized intervals rr i with regard to the principal horizontal axis X 0 ; g) storing a pair of values consisting of a mean value RR MV of the sequence of intervals RR i and the standard deviation SO L ; h) selecting further sequences of intervals RR i and for these further sequences of intervals RR i the steps c) to g) are carried out; i) producing a training intensity curve from the pairs of values, determined in steps c) to h) of the heart frequencies HF (HF =1/RR MV )corresponding to the mean values RR MV and standard deviations SO L ; and j) through comparing the most recently determined heart frequency HF with the training intensity curve a current, specific training intensity is determined for the person.
