Summary

Mark Burnley, PhD, is an exercise physiologist at the University of Kent. Mark's main research interests include oxygen uptake (VO2) kinetics, where an important application is how to optimally use warm-ups, as well as Critical Power, which forms the transition point (or transition area) between the heavy and severe exercise domains. Because of the non-steady-state nature of exercising above CP, it has significant importance in a large number of training and racing applications. IN THIS EPISODE YOU'LL LEARN ABOUT: -VO2 kinetics - what does it mean? -The fast and slow components oxygen uptake -Heavy priming exercise and its effects on VO2 kinetics (or the importance of a good, specific warm-up) -Critical Power (CP) - what is it and how does it compare to other "threshold concepts" -How to assess CP and use it in training -How fatigue develops differently in the different exercise intensity domains (moderate, heavy, severe) and interventions to minimise fatigue SHOWNOTES: https://scientifictriathlon.com/tts257/ SCIENTIFIC TRIATHLON AND THAT TRIATHLON SHOW WEBPAGE: www.scientifictriathlon.com/podcast SPONSORS: Precision Hydration - One-size doesn't fit all when it comes to hydration.

0:00.0	That Traffle Show, 257.
0:05.2	Hey, what's up, everybody, and welcome back to another episode of That Traathlon Show.
0:23.4	The podcast presented by Scientific Traathlon.com.
0:27.2	I'm our host Michael and on today's episode, I interview a Dr. Mark Burnley.
0:32.1	Mark is an exercise physiologist at the University of Kent and his main research interests include oxygen uptake kinetics or
0:40.2	VO2 kinetics which has really important implications for how to design optimal warmups before races in
0:49.5	particular it can be the difference between winning and losing at least in more intense shorter races.
0:56.0	But even for things like triathlons where the swim start can usually be pretty hard, this is an important topic that we'll get into.
1:02.8	We'll also discuss critical power, which is another area where Mark has done a lot of research.
1:08.7	And this is the transition point, or more correctly,
1:12.7	the transition area between the heavy and the severe exercise domains. And because of the non-steadistate
1:19.6	nature of exercising above critical power, this also has significant importance in a large
1:25.9	number of training and racing applications that
1:28.2	will get into in the interview. But before that, big thanks to our sponsors.
1:33.8	First, we are precision hydration that you can find on precision hydration.com.
1:38.4	Precision hydration has developed an online sweat test, which is simply a questionnaire,
1:43.5	that you can fill out in just a few minutes
1:45.8	and it will give you a great ballpark estimate for how much sodium you lose in your sweat
1:51.3	and that will then also automatically generate a racing plan that you can use for how you
1:57.7	should hydrate during your races and And this is something that I highly recommend
2:01.4	to do as to get a bit of a benchmark or a starting point for your own experimentation. And that's
2:07.6	also how precision hydration. And if you listen to my interviews with Andy Blow, what he recommends
	...
