Abstract
Methods and systems are disclosed for determining an anaerobic threshold and/or an oxygen consumption rate in a human or animal subject. The methods include exposing a tissue of the subject to illumination radiation, collecting emitted radiation from the tissue, the emitted radiation including a portion of the illumination radiation reflected or transmitted from the tissue, processing the emitted radiation to form a spectrum of the tissue, and determining, based on the spectrum of the tissue, the anaerobic threshold and/or the oxygen consumption rate of the subject.
Claims9
An apparatus, comprising:
- a spectrometer configured to detect light emitted from a tissue of a human or animal subject, and to determine a spectrum of the tissue from the detected light;
- and
- an electronic processor coupled to the spectrometer and configured to:
- determine a plurality of spectra of the tissue;
- determine a plurality of pH values of the tissue, wherein each one of the plurality of pH values is obtained from a different one of the plurality of spectra;
- and
- determine an anaerobic threshold of the subject based on the plurality of pH values of the tissue and on corresponding values of a measure of exercise intensity.
