VLaMax, Polarised training, Fatigue and Complexity with Mark Burnley, PhD | EP#331
That Triathlon Show
The Effects of Fatigue in High Intensity Exercise
We lose complexity as we fatigue, according to a new study. The research was carried out using high density e m g electrodes on the human body. It could be used by wearable tech companies to monitor fitness levels in real time.
Mark Burnley, PhD, is an exercise physiologist at the University of Wolverhampton. In this episode, we discuss the VLaMax, polarised training (and it not being optimal for endurance athletes), and using measures of complexity to assess fatigue. This is part two of a two-part interview with Mark.
IN THIS EPISODE YOU'LL LEARN ABOUT:
-VLaMax: the background, reason for recent surge to popularity, and the mechanistic and practical issues with measuring it
-Polarised training is not optimal for endurance athletes: the arguments against polarised training being an "ideal" training intensity distribution, and why quantifying training intensity distributions may not be the smartest thing to do in the first place
-How measures of complexity (e.g. Approximate entropy ApEn, alpha-exponent of Detrended Fluctuation analysis DFA) can be used to assess fatigue, and the potential applications thereof
