If you want to support, and learn, you can donate here Show notes This week on The Spotlight, we put big claims, bold performances, and comeback stories under the microscope. In Discourse Digest (00:00), we discuss why Beatrice Chebet’s near-world record 5000m is not a miss, just a delay. Then we shift to the French Open, where Carlos Alcaraz outlasted Jannik Sinner in a classic. Gareth asks whether Sinner’s loss might be exactly what tennis (and Sinner) needed, and how their rivalry and reputations will shape the sport’s next era. Listener Lens (15:50) features a question from listener Simon, returning from an injury-enforced layoff. Ross offers guidance on regaining lost fitness, why retraining happens faster than we think (the 1:2 rule of thumb), and why doing less will eventually give you the right to do more. Center Stage (22:34) is all about carbs, fat, and fuel—sparked by a tweet from Prof Tim Noakes after the Comrades Marathon. Having watched the race, Noakes claimed that “not a single lead athlete tried to ingest 90–120g/hour of carbohydrates,” and that they “know they don't need carbs to win Comrades” because “fat can provide essentially all the required energy.” We put those claims under the Spotlight, and checked with the elites. Turns out, they were targeting exactly those carb intakes. We explore the science and discover a huge capacity to increase fat oxidation as a function of diet, training and exercise intensity. But that doesn't mean carbs don’t matter - we dig into evidence that carbs improve performance, delay fatigue, and enhance recovery. The real problem? Extremes. Whether it’s high carb or no carb, just because you can doesn’t mean you should. And finally (53:44)—Padel and Pickleball are booming. Why are they so popular, and will they dethrone tennis as the world’s favourite racket sport?

It won't cost you even 2% of what the Enhanced Games are charging, and our advice actually works, and is safe! Show notes At 1:09. In the Discourse Digest news roundup, Gareth and Ross tackle three stories where science and policy collide. First up, the Enhanced Games’ latest scheme—inviting people to pay $399/month for performance-enhancing drug guidance under the guise of anti-aging and health. Then, a look at World Boxing’s new sex screening policy for the women’s category: what the language really means, why it matters, and how sport might manage it. Finally, a compromise attempt in California where extra medals are awarded to navigate the inclusion of trans-identified males in girls’ sport—Gareth and Ross explore what’s gained and lost in that trade-off At 25:39. A new Listener Lens feature this week comes from Discourse member Tony, who asks: how should you judge your warm-up before a race? Ross and Gareth explore what a warm-up really prepares—neuromuscular readiness, not just heart rate—and share insights from fellow Discourse members who’ve fine-tuned their routines At 33:35. And Finally (not quite today!), British ultra runner William Goodge is under fire after suspicious data emerged from his trans-Australia record attempt. Ross recalls a similar case he investigated, and the duo asks: why, in an age of abundant tracking tech, are we still debating whether these runs really happened? At 42:58. This week’s Center Stage belongs to one of the most dramatic finales in recent Grand Tour history. Simon Yates won the Giro d’Italia with a stunning final mountain stage raid—equal parts science, strategy, and surprise. Mike and Ross unpack the physiology and tactics behind Yates’ triumph: Did del Toro and Carapaz concede the maglia rosa because they hit their physiological limits, or were they undone by tactical missteps and pacing errors? And what about Wout van Aert, the satellite rider whose power and presence may have changed the race’s outcome? From record-breaking efforts to tactical stalemates, we break down the science that decided the Giro Links Nick Harris on the Enhanced Games dealWorld Boxing announce the sex screening policyTony's question about Warmup HR, as discussed in Listener Lens (Discourse members only)Story of Rob Young's questioned ultra performance, with a link to the report I co-wrote on itAnalysis of Yates' record performance on the FinestereDerek Gee's Strava file Hosted on Acast.

    Spotlight: Breaking the Physiological Bank in Training, and Rethinking Rugby’s Red Card

    Join Discourse Gareth Davies, Mayor of The Real Science of Sport, is ready to welcome you as a citizen of our VIP community! To join the conversation, make a monthly pledge at Patreon.com and get access to the shared expertise and passion of fellow listeners Show notes In this week’s Spotlight, we tackle an intriguing training question from a listener in our Discourse community: do short surges during easy or moderate training days undermine the training benefit? To explore this, we look to the current Giro d’Italia, where Richard Carapaz and rising star Isaac del Toro offer real-world examples of how intensity, even in brief bursts, may create a significant physiological cost. While small deviations from planned intensity are not only acceptable but often necessary, trouble arises when these efforts become too frequent or too intense. We introduce the concept of a physiological budget, and how consistent overspending can lead to a kind of training “bankruptcy,” where the cost outweighs the benefit. We break down how it's the intensity that exponentially increases physiological stress, and how to manage that cost wisely in your own training. Then we shift gears to rugby, where the red card rule is about to undergo a significant transformation. Under the new law, a team will no longer play with 14 players for the rest of the match—after 20 minutes, they can bring on a replacement. In response to split opinion in the Rugby community, Gareth asks: “What’s the big deal?”. Ross explains why this change has divided the sport, delving into the broader context of concussion prevention, and how sanction was meant to carry the message for behaviour change. Ross shares insights from his newly published paper showing that women are concussed in the same way as men, adding a crucial layer to the ongoing head injury debate. In our news wrap, we stay on safety, where the NFL has decided not to ban the controversial "tush push". We examine how that decision parallels rugby’s own risk-management principles. Beatrice Chebet ran the second-fastest 3000m in history last week, putting herself onto a controversial list of Chinese names who had appeared to move that World Record out of reach. Ross offers a prediction that it's a matter of time before the WR falls to Chebet (along with others). And the Enhanced Games claim a “world record” performance of its own, leading us to again discuss the ethics, science, and inevitable sales pitch driving the campaign, and why giving oxygen to the now transparent anti-aging commercial objectives of the Games may not be a good idea.

Become part of the “Science of Sport” Discourse community via Patreon. Show notes This week on Spotlight, we take a tour through some of the big stories in sport and sports science right now—from race tactics and concussion protocols to doping ethics, expert credibility, and how we identify and develop talent. We start with a lively discussion on the Giro d’Italia and that gravel stage. Was it thrilling unpredictability—or dangerous chaos? As the General Classification gets a dramatic shake-up, we debate whether the pursuit of entertainment justifies what some see as random, unfair risk and compromised race integrity. Do stages like this belong in a Grand Tour, or are they an unwelcome injection of chance into a sport built on precision and control? From there, we shift to cycling’s ongoing concussion challenges. Jonas Vingegaard’s recent comments compel questions about whether current policies do enough to manage brain injuries. Despite a policy that asks multiple people in the race to identify possible cases, the sport appears to be struggling to accurately identify who gets tested, when and how. Are critical medical decisions still slipping through the cracks because the wrong people, with misaligned incentives, are being asked to make them under pressure? Then it’s time for our first featured topic: the evolution of the Enhanced Games. With swimmer James Magnussen chasing a chemically-aided world record and a million-dollar prize, we unpack the ethical and medical dangers of performance enhancement. What are the risks—for athlete health, for fairness, and for the messages it sends to the next generation? Next, we ask: How do you know who to trust? In an age of slick communication and pseudo-expertise, we explore the credibility of experts, and discover why true experts often sound less confident, not more. Ross explains how confidence can be a red flag, and why uncertainty and nuance are often markers of real scientific thinking. Finally, we dive into the messy reality of Talent ID. Ross explains four common errors—especially the “ghosts” created when resource-strained systems make early, high-stakes decisions that can harm both performance and people. We close with a brief segment on doping in Ironman, and why the “contaminated meat” excuse likely doesn’t hold up—though science says it’s not entirely impossible.

Support us with a small monthly donation on Patreon and unlock access to our exclusive Discourse community—deep dives, hot takes, and smarter sport talk await! In this week’s Spotlight, we dive into the science behind an eye-watering nutrition number: 200 grams of carbohydrate per hour. That’s what elite Ironman Cameron Wurf reportedly consumed during a record-breaking bike leg in Texas. But does the body actually use it all—or is there a ceiling to sugar oxidation? Ross and Gareth break down a recent study comparing 120g and 90g per hour in trained cyclists, revealing how much of that fuel actually gets burned, and whether it has the purported effects on fuel use during exercise. Before we hit the carb overload, we’ve got a mix of big stories from across the sporting world: 🎾 IV drips and bans in tennis – Australian pro Max Purcell has been hit with an 18-month doping ban for intravenous vitamin infusions. We unpack the rules, his case and discover some other athletes who have fallen foul of the IV rule 🏏 Cannabis and cricket – South Africa’s Kagiso Rabada served a one month suspension for a ‘recreational drug’. We revisit the criteria WADA uses to ban substances and ask: should cannabis really be on the list? 🏃‍♂️ The teen sprint takeover – A 17-year-old ran a wind-assisted 9.92s, with two ninth-graders just behind him, breaking 10.2s. They join Gout Gout as teen phenoms with bright futures 🔬 Publish, perish—or post? – We reflect on a growing reality in science: if researchers aren't visible and able to communicate beyond journals, they risk irrelevance. Is it now “share or disappear”?

Become a member of “The Science of Sport” community by joining with a small monthly pledge on Patreon — and be part of the conversation behind the conversation. Show notes In this week’s Spotlight, we open with a brisk roundup of major stories from the world of sport and policy. We look at new developments following the UK Supreme Court ruling on the Equality Act, including the first tangible policy response. We also revisit the resolution of the tragic ice hockey case involving manslaughter charges, and World Athletics’ announcement of its “Ultimate Championship” event—an innovative idea, but not without flaws. Gareth raises some pointed criticisms about the competition format and the puzzling exclusion of key athletics disciplines. Next, we talk talent. The NFL Draft always offers a window into the world’s most elaborate selection process—but also its inefficiencies. We reflect on how early selection often produces more busts than brilliance, yet remains largely unchanged due to structural inertia. A 14-year-old’s blistering 35-ball century in the IPL leads us to discuss a surprising link between cricket scoring and endurance pacing, and how this informs the Duckworth-Lewis-Stern method. From there, we shift to the core topic of the episode: scientific integrity. Gareth reflects on our recent Spotlight's deep dive into how scientific papers are made, and our most recent feature podcast on the Boston Marathon and Mike's experiences testing Puma's new shoe. The conversation expands into questions of independence in scientific research and evidence, with specific reference to Puma’s bold claim that their new shoe is “the fastest ever", and why that statement is, at best, premature. But we also give credit where it’s due, praising the transparency and almost certain publication of the results of the brand’s testing, as well as the researcher's realism about trust in their lab's research. And amid it all, Ross shares some personal news—stepping away from his School Academy High Performance and development role, while reflecting on missed opportunities and unrealized HP philosophies. Links The Scottish FA acts to protect women's footballAnd the English FA are, apparently, considering itThe case against ice hockey player Matt Petgrave is droppedAn analysis of draft picks that shows how high the proportion of "busts" isHere's a preprint of the Hoogkamer evaluation of the Puma supershoe - this is not peer-reviewed yet, but I strongly suspect that a peer reviewed version of this is on the horizonThe best community discussion you'll read on Supershoes, courtesy our Discourse members (Members only access - you know what to do!)
