Episode notes
Proper Moxy Placement
- Place the Moxy Monitor on an active muscle belly for accurate SMO2 readings.
- Test placement by doing quick quarter squats and adjust until SMO2 decreases predictably with load.
Dave's Experiment with Moxy Placement
- Dave Schell tried various quad muscles to find reliable SMO2 responses during efforts.
- He aims to use SMO2 to adjust interval intensity and determine when to stop workouts based on muscle oxygen data.
SMO2 Plateau and Muscle Recruitment
- SMO2 may plateau during tempo efforts as the muscle maximizes oxygen use before recruiting others.
- Different quad muscles can show distinct SMO2 patterns linked to fatigue and effort intensity.
