Summary

Mehdi Kordi, PhD, is a track cycling coach (sprinting in particular) working with the Royal Dutch Cycling Federation. In Tokyo, the Dutch track sprinters brought home multiple golds and medals, and Mehdi joins us to discuss how these athletes train to be the fastest on the planet. Also we discuss the physiology of W' and how it relates to neuromuscular function, and other bits and pieces from Mehdi's research. IN THIS EPISODE YOU'LL LEARN ABOUT: -Mehdi's take on the Olympics in Tokyo and how his team performed -How do track sprint cyclists train? -The relationship between neuromuscular function and W' (anaerobic work capacity) -The importance of muscle size (rather than neural functions, fiber type etc.) and maximum force capacity on W' -What sort of strength training might be used to improve W'? -Reliability and sensitivity of the Notio Konect aero sensor SHOWNOTES: https://scientifictriathlon.com/tts307/ SCIENTIFIC TRIATHLON AND THAT TRIATHLON SHOW WEBPAGE: www.scientifictriathlon.com/podcast/ SPONSORS: ROKA - Exceptional quality triathlon wetsuits, trisuits, swimskins, goggles, performance sunglasses as well as prescription eyeglasses and sunglasses.

0:00.0	The Traathlon Show, 307.
0:05.0	What's up, everybody, and welcome back to another episode of that triathlon show.
0:23.5	The podcast presented by Scientific Traathlon.com.
0:27.2	I'm your host Michael, and on today's episode, I interview Dr. Mejde Kordi.
0:31.4	Mejde is a track cycling coach, in particular in sprinting, currently working with the Royal Dutch Cycling Federation.
0:38.6	The Dutch team had a great Olympic Games, bringing home multiple goals and other medals.
0:43.8	So we will discuss that, and we'll discuss generally how a track sprinters train.
0:49.1	And we will discuss some of the research that made it has done.
0:52.0	So lots of bits and pieces here that I'm sure you will
0:55.3	enjoy. But before that, big thanks to our sponsors, precision hydration. Precision hydration create
1:00.8	electrolyte products that you can match to how you sweat and fueling products that make it
1:04.6	easy for you to hit your numbers. When it comes to electrolytes and sodium in particular,
1:09.9	remember that we all have different sweat rates and we also have very different sweat sodium concentrations.
1:16.1	So for example, I personally lose more than 2,000 milligrams of sodium per liter of sweat.
1:21.8	And on the bike in a race, I might sweat around 1.5 liters per hour.
1:26.7	Of course, this depends a bit on the conditions.
1:29.2	My aim is to replace at least 70% of the sodium that I lose. So that means that, let's say,
1:35.0	for a 7.3 bike, I would need to consume at least 4,200 milligrams of sodium just on the bike.
1:41.1	That depends on how fast or slow the course is. If it's slower, then I'll need to
1:44.7	consume more than that. But on the other hand, somebody who loses 500 milligrams per liter of
1:49.5	sweat and sweats only 0.8 liters per hour would need to replace about 8 times less than that
1:56.3	for the same duration out on the course. Precision, durations, products and free online sweat test or advanced in-person
