3/ SmO2(%) distinguishes elite from average athletes (mean age 18 years)

Here's what you're looking for: the longer the your muscles can remain below an oxygen saturation level of 10% (SmO2<10%) the more stamina you have for intense exercise.

For example, normal people can…

4/ Two national-level swimmers (mean age 18) in the study spent 152 and 126 seconds at SmO2(%) >10%, corresponding to 50.6% and 42% of the 5 minutes analyzed, their non-national level peers could only hold that level for 18% and 2% of the workout (4).

The 2 national athletes…

1/ Muscle Oxygen Saturation SmO2 is a fitness marker revealing the youthfulness and vitality of your muscles.

While VO2 Max indicates systemic capacity of oxygen utilization and cardiorespiratory fitness, SmO2 shows how adaptive your muscles are to stress and strain.

2/ To track my SmO2, I am using a wearable MOXY sensor, which is used by professional athletes and validated in peer-reviewed clinical exercise research (3,4).

MOXY device uses a non-invasive imaging technique called NIFR (Near Infra-Red Spectroscopy) to track muscle tissue…

My muscles have the oxygen capacity of 18-year-old elite athletes.

Most people can barely reach 10% muscle oxygen saturation, but elite athletes can sustain it for longer periods. Important because muscle = longevity (1,2).

Here's what you need to know.
