Measure muscle oxygen, the most critical factor in athletic performance and know your lactate threshold real-time.

The Humon Hex is the first clinically validated muscle oxygen tracker that allows athletes, sports teams, and performance labs to optimize workout intensities, minimize injury, and monitor progress.

Humon started out of MIT research on the premise that technology and biology were on a collision course. The result of this intersection would create the next generation of sensors and products allowing users to understand more about their own bodies and as a result, be their better selves. Humon was born out of that research.

Humon's Mission

To provide people with unprecedented visibility into their bodies and empower them with the required actionable insights to be their best selves.

How it works:

The Humon Hex uses near-infrared spectroscopy to measure the oxygen saturation in muscles (also referred to as SmO2 % or Muscle Ox %). LEDs emit light into the muscle tissue and several detectors measure the light intensity as it propagates through the muscle.
Since oxyhemoglobin (HbO2) and deoxyhemoglobin (Hb) have different absorption spectra in the near-infrared wavelength range, the Muscle Ox can be calculated.
In other words, the Hex looks at the color of your blood in the muscle in real time and from that determines your Muscle Ox.
