Combining Muscle Oxygenation and Acceleration Data With NNOXX

Muscle oxygenation reveals how much oxygen your muscles are using during exercise. If SmO2 is decreasing, you’re using a higher percentage of available oxygen to power activity; if it’s increasing, you’re using less. This insight is invaluable for endurance athletes, CrossFitters, climbers, and strength athletes alike.

However, muscle oxygenation data alone isn’t always straightforward or actionable. For example, let’s say your muscle oxygenation is progressively dropping during exercise. It is because your power output is increasing, requiring your muscles to utilize more oxygen to match the increased demand? Or, is it because you’re getting fatigued, despite maintaining a stable power output? These scenarios require different strategies, but SmO2 data alone can’t differentiate between them.

The team at NNOXX has solved this problem by integrating accelerometers that measure 50 times per second into our wearable device, allowing us to capture changes in both movement patterns and internal physiological data simultaneously. This innovation gives us a unique advantage over other muscle oximeters and provides a more comprehensive understanding of performance.
