DFA alpha-1: A non-invasive, cheap option for estimating the aerobic threshold with Bruce Rogers, MD | EP#329
That Triathlon Show
Real Time Alpha One After the Ultra Marathon
The alpha one after the ultra marathon was well below point five. It was in that really high intensity domain well above the FTP type of value. Yet, they were still able to run a half-marathon without any training at all.
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
