Michael Liberzon is a Toronto-based triathlon coach, bike fitter and aero tester, and host of the Endurance Innovation podcast. In this episode Michael explains what gains can be made by upgrading from a road bike to a Time Trial bike, and how things like the type of course and terrain can impact your choice of bike.  IN THIS EPISODE YOU'LL LEARN ABOUT:

-Expected time gains for a TT bike vs. a road bike over sprint, Olympic, half and full distance races on relatively flat courses. 

-Is there a point where a course is so hilly that it makes sense to race on a road bike? 

-When might it make sense to simply put extensions on a road bike rather than purchasing an entirely new bike?

-At what speed does it make sense to get out of the aerobars and sit up when climbing? 

-Other considerations for racing on hilly courses like disc wheel and hydration setup

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
