If you’re using a Tymewear strap with the Tymewear Garmin Connect IQ app, AI Endurance now automatically extracts your respiration frequency from your FIT files. No setup needed, it just works with your existing Garmin sync.
Tymewear gives us the most direct field measurement of breathing rate available. We use it to validate HRV-based threshold detection and we’re building toward RF drift as a durability marker alongside heart rate and DFA alpha 1. More on that in our new blog post comparing Tymewear, HRV-derived RF and Breeze.
