THE SCIENCE

HOW IT WORKS

The Humon Hex uses near-infrared spectroscopy to measure the hemoglobin saturation in muscles (also referred to as SmO2).

LEDs emit light into the tissue and detectors measure the intensity of light that propagates through the muscle.

Since oxyhemoglobin (HbO2) and deoxyhemoglobin (Hb) have different absorption spectra in the near-infrared wavelength range, the SmO2 can be calculated.


SmO2 is the balance between

SmO2 = [HbO2]/[HbT]
[HbT] = total hemoglobin concentration

The Humon Hex helps endurance athletes train smarter by monitoring the way their muscles are using oxygen in real-time and empowering them with the information they need to know when and how hard to push themselves.
