Summary

Jamie Stanley, PhD, is a sports physiologist with the South Australian Sports Institute. Jamie did his PhD thesis on the topic of Heart Rate Variability (HRV), but in his applied sports science role today he has a wide breadth of performance and recovery optimisation expertise, and we tap into that expertise on a number of interesting applied sports science questions in today's interview. IN THIS EPISODE YOU'LL LEARN ABOUT: -The responsibilities and day-to-day work of Jamie in his role as sports scientist supporting athletes and coaches -How to use HRV to monitor training adaptations -Looking at medium and long-term HRV trends rather than daily values -Tools of the trade: recommendations for tools with which to measure HRV and analyse the data -Tracking resting heart rate, sleep duration, and sleep quality -Lab and field testing - who should use what kind of testing, and when? -Best practices for monitoring training load -How to find your individual physiological limiters, and when to work on strengths vs. weaknesses -Continuous blood glucose monitoring SHOWNOTES: https://scientifictriathlon.com/tts308/ SCIENTIFIC TRIATHLON AND THAT TRIATHLON SHOW WEBPAGE: www.scientifictriathlon.com/podcast/ SPONSORS: Precision Hydration - Want to optimise your performance in hot or humid conditions, avoid cramping, and make sure your hydration is on point?

0:00.0	The Traathlon Show, 308.
0:05.0	Hey, hey, what's up, everybody, and welcome back to another episode of That Traathlon Show,
0:23.0	the podcast presented by Scientific Traathlon.com.
0:26.6	I'm your host Michael, and on today's episode, I'm Dr. Jamie Stanley.
0:30.6	Janie is a sports physiologist with the South Australian Sports Institute.
0:34.8	His PhD was on the topic of heart rate variability, which we will talk about
0:38.5	quite a bit in the first half of this episode. But in his role as an applied sport scientist
0:43.4	today, he does way more than just heart rate variability. So we will go into a number of
0:48.3	questions and topics regarding how to apply sport science in the performance and recovery
0:53.8	optimization of endurance athletes.
0:56.0	I hope will be really, really interesting for you to hear and there will be some actionable
1:00.5	takeaways as well. But before that, big thanks to our sponsors, precision hydration.
1:05.8	Precision hydration create electrolyte products that you can match to how you sweat and fueling
1:09.7	products that make it easier for you to hit your numbers very easily due to their 30 grams of carbohydrate
1:16.0	per serving principle. When it comes to electrolytes and sodium in particular, remember that we all
1:21.8	have different sweat rates and very different sweat sodium concentrations. So personally, for example,
1:27.1	I lose more than 2,000 milligrams of sodium per liter of sweat.
1:31.0	And on the bike in a race, I sweat around 1.5 liters per hour.
1:35.3	And with my aim being to replace at least 70% of that, I need to consume at least 4,200 milligrams
1:41.6	of sodium just on the bike in a 7.3 race, for example.
1:46.3	But somebody who, on the other hand, might be losing 500 milligrams per liter and sweat
1:51.1	less than I do, let's say 0.8 liters per hour, they would need to replace a significant
