In this episode, we sit down with Dr Andrew Koutnik to unpack one of the most discussed sports science reviews in recent years. Drawing on more than 100 years of research and a series of tightly controlled trials, we examine evidence that challenges the long-held belief that more carbohydrates automatically lead to better performance.

We explore why muscle glycogen and carbohydrate oxidation do not consistently predict performance, how athletes can sustain high-intensity and endurance output with much lower carbohydrate intake, and why protecting brain energy may be a key limiter during exercise.

The conversation also examines why some highly trained athletes still show markers of poor metabolic health, what this means for current fueling guidelines, and why context matters when translating science into real-world practice.

In this episode, we sit down with François Fourhet to trace a career that has moved from hands on clinical practice to global performance environments, research leadership, and now consulting and teaching.

François shares the three major chapters of his journey: early years as a sports physio in Reims, nearly a decade in Doha within Aspire and Aspetar, then his Swiss chapter at Hôpital de la Tour where he helped build a research driven physiotherapy department and later led it. Along the way, they unpack what it really takes to make interdisciplinary performance support work, how François shifted into research without losing the practical thread, and why dissemination matters as much as publishing.

The conversation also gets tactical: ankle return to play, why isokinetic testing is misunderstood, how curve based analysis changes decision making, and the story behind Ankle Go, the free tool designed to help clinicians make smarter calls after ankle injury. If you work in rehab, performance, or team leadership, this episode is packed with ideas you can use immediately.

In this episode, we sit down with Professor Arne Güllich to unpack one of the most talked about sports science papers in years, recently published in Science. Drawing from data on more than 30,000 high performers across sport, music, chess, and science, the conversation challenges the belief that early dominance and early specialization are the keys to elite success.

Arne breaks down the now viral performance trajectory figure, explores why most world class adults were not standout juniors, and explains what truly separates those who peak at the highest level from those who plateau. The discussion moves from theory to practice as Paul reflects on his role as a parent of a 15 year old swimmer, asking the questions many parents and coaches are quietly wrestling with.

This episode is essential listening for anyone involved in youth sport, talent development, or long term athlete health and performance.
