Discourse is the best Sports Science community on the internet, and yes we are biased. But if you want to see for yourself, membership is a monthly pledge away, and then you too can gain access to opinion, insight and analysis from The Real Science of Sport army!

Show notes

This week in Spotlight, we kick of with a Discourse Digest exploring the UCI's equipment rules — most notably, 40cm minimum handlebar width. It may seem like a technical tweak, but the implications are significant: many female cyclists will now have to widen their bars to comply, sparking criticism that the rule is not only arbitrary but discriminates against women. We dig into what it says about decision-making at the UCI, and how governance in the sport appears to be crying out for systematic, deliberate and openly communicated processes.

In Listener Lens (11:56), we tackle a great Discourse question from Liam, a coach working with a 13-year-old female runner whose progress has stalled. We explore why this happens to young athletes, especially girls, and how the short-term incentives we create in youth sports cause challenges for the most well-intentioned coaches and parents. It’s a conversation about patience, perspective, and reframing our expectations to accept that sporting development is very rarely linear.

Then, in a new Ross Replies segment (29:20), a question from Nicol on how the body switches from fat to carbs during exercise opens the door to a deep dive into metabolic regulation. We break down what controls fuel selection during exercise, and why a new paradigm has emerged: instead of trying to promote fat oxidation to spare carbohydrates, elite athletes are now trying to minimize it. Why? To enhance performance by maximizing oxidation efficiency with carbs.

In Center Stage 51:57), we discuss some of the tech details that have emerged in support of Faith Kipyegon’s sub-4:00 mile attempt, and wonder what the quiet collapse of the Grand Slam Track series means for the sport? And finally (64:54) Gareth notes that Mondo Duplantis' pole vault dominance shows no signs of abating, leading us to wonder why some dominance is lauded, while others are doubted, and to reflect on huge sporting mismatches.
