The Physiology of Endurance Running Podcast

Dan & Owain are joined by Sian Seccombe (Sian Secc on socials) to talk about body weight, REDS and social media, especially nutrition social media! A third instalment in the series of episodes about body weight and its relationship with running performance, Sian talks us through the consequences of an energy imbalance, along with tips on spotting and treating this!

Following the recent episode about body weight, Dan & Owain interview Dr James Fleming about body composition and the work of an applied practitioner in the nutrition space.
James is a lecturer at St Mary's University, with experience in nutrition and body composition. He's also hosting an Adolescent Athlete Conference in June 2027. Drop him an email if you're interested in attending (james.fleming@stmarys.ac.uk)

Dan & Owain take a deep dive into New Zealand blackcurrants and anthocyanins, specifically looking at their possible benefit in the heat. They also critically discuss applying research in the supplement space, and the evidence that exists for blackcurrants and other supplements on the market.

In the last few years, lab testing has exploded as an industry - expanding beyond a few universities offering tests in their laboratory. Unfortunately not all tests are equal, and having seen more bad tests, Dan & Owain talk through what you should be looking for from a lab test.
Send us in your tests and we might do an episode talking through some of the bad ones soon!
