The Heart Rate Variability (HRV) Logger app is finally available on both the Apple Store and Google Play, including DFA alpha 1 to analyze exercise intensity with respect to the aerobic threshold What's the DFA alpha 1? A non-linear HRV feature which can be used to estimate the aerobic threshold. In particular, when DFA alpha 1 is below 0.75, it means the intensity is higher than the aerobic threshold (so it defines "low intensity work", as typical in a polarized training program). If alpha 1 is above 0.75, the intensity is considered low, or below the aerobic threshold How can you try it? The HRV Logger app requires an external sensor, and for this specific analysis, we highly recommend a Polar H7 or 10 for its accuracy. Garmin dual straps should also work well.
