Abstract: A first arithmetic circuit detects R waves from an electrocardiogram waveform measured by electrocardiograph and obtains an interval (heartbeat interval: RRI) between adjacent R waves. A second arithmetic circuit obtains an instantaneous heart rate for each beat indicated by an R wave from the interval obtained by the first arithmetic circuit. A third arithmetic circuit obtains a smoothed heart rate obtained by smoothing the instantaneous heart rate for each beat calculated by the second arithmetic circuit. A fourth arithmetic circuit obtains a signal-to-noise ratio of the electrocardiogram waveform using the instantaneous heart rate and the smoothed heart rate.

Abstract: An electromyography processing apparatus 1 includes a storage device 10 that stores electromyography data 11 of a predetermined muscle, an onset detection unit 23 that detects an onset section of the electromyography data 11 in which an electromyography increases by a repetitive exercise performed by an athlete, and an ON/OFF indicator processing unit 25 that calculates a variance a probability distribution acquired by normalizing a root-mean-square value of the electromyography for each onset section, and outputs the calculated variance as an ON/OFF indicator for each onset section.
