Bruce Rogers, MD, is one of the researchers behind the research on using the non-linear HRV-based marker DFA alpha-1 (which can be be measured non-invasively and for free or very cheaply) to assess the aerobic threshold. We discuss this research and its applications in this interview.   

IN THIS EPISODE YOU'LL LEARN ABOUT:

-What is DFA alpha-1, and how can you measure it? 

-The current evidence behind using DFA alpha-1 as a marker for the aerobic threshold (LT1/VT1)

-Testing protocols, and hardware and software requirements for testing

-Limitations and challenges, including devices, artifacts, and training modality

-How to incorporate DFA alpha-1 testing in your training

-Other potential applications of DFA alpha-1, including assessing fatigue and durability
