Abstract
A device is provided, which is capable of determining the maximum oxygen uptake quantity without the restriction of a large device or requiring troublesome operations to be carried out. The device displays the upper and lower limit values for the pulse rate corresponding to an appropriate exercise intensity, and realizes in a wireless manner by means of optical communications the sending and receiving of information such as pulse wave signals to and from an information processing device which processes pulse wave information. The device is provided with a pulse wave detector 101 for detecting the test subject s pulse waveform; an FFT processor 103 for determining the test subject s heartbeat rate from the pulse waveform; a body motion detector 104 for detecting body motion when the test subject is running; an FFT processor 106 for determining the pitch from body motion during running by the test subject; exercise intensity calculator 108 for determining pitch, the test subject s stride, and the exercise intensity from body motion during running; and a nomogram recorder 109 for recording the relationship indicated by an Astrand-Ryhming nomogram, and determining the maximum oxygen up…
