Science to Apple Watch in 24 hours
What is it?
The Heart Rate Variability Logger app I discussed a few posts ago has been extended to use the Apple Watch as a display, so that you can see in real-time HRV features as you exercise, including the DFA alpha 1
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)
When can you try it?
The HRV Logger app is available on the Apple Store. It requires an external sensor, and for this specific analysis, we highly recommend a Polar H10 for its accuracy. The Apple Watch extension will be available in a few days
