This week's Spotlight focuses on the doping case of Marketa Vondrousova's four year ban for refusing to provide a sample during an out of competition test in 2025. We also return to the USA for some Football World Cup insights, cover some injury science with implications for Keely Hodgkinson's season, and issue a call to arms for members ahead of our durability experiment. Here's what's on the show today:

• A leg-breaking tackle in the Canada versus Qatar game sparked a debate among our listeners on Discourse that cuts to the heart of how sport punishes dangerous play. Should the sanction reflect what the player did, or what happened as a result? Ross draws on his rugby background to explain why outcome-based punishment is more common and more defensible than it first appears, and why intent is almost impossible to use as a standard
• Travel demands at the World Cup are discussed by a listener in this article - we ask whether this could be decisive to the outcome, which takes us on a journey into travel load and its implications for performance
• The momentum graphics appearing on screen during World Cup broadcasts continue to prompt discussion among our listeners. We explore how they actually work, why they might be interesting to fans but are almost certainly meaningless to coaches, and what question you would need to answer before you could trust them at all?
• Our main feature is former Wimbledon champion Marketa Vondrousova, now banned for four years for refusing a doping test. We explain why the anti-doping system has to treat a refusal as the equivalent of a positive test, why her own social media post on the night made things worse for her, and why comparing her ban to the Sinner and Swiatek cases misses the point entirely
• Keely Hodgkinson withdrew from the 400 metres at the UK Athletics Championships in tears after experiencing "hamstring tightness" before the race. We explore why, even if this turns out to be nothing, the pattern of recurring hamstring tightness is worth paying close attention to, and shares the sobering statistics on hamstring re-injury rates and risk factors that make this more than just a precautionary withdrawal
• World Rugby has permanently approved a lower tackle height for community rugby, but with a catch: different unions can choose between the waist and the sternum as their legal limit. We discuss why that flexibility exists, what it means in practice, and what would have to be agreed before any change could come to the elite game
• A cyclist suffered a concussion during the Tour de Suisse and continued racing for several more stages. Gareth's initial reaction is that it's another policy failure by the UCI, but we discuss it and discover a number of scenarios that would explain how it happened without any fault from the UCI
• And finally, a call to action for members. Our Applied show this Friday will cover durability, and we are turning it into a live global experiment. Over the coming weeks we will be asking supporters to complete a set of time trials on the bike, and we will use that data to build your power duration curve, work out your W prime, and calculate your durability index. All the details will be on Discourse and Discord for members

Oh, and why is Messi so comparatively poor at penalties? Our previous guest Ben Lyttleton shares a piece he wrote on why the best ever is average from the spot!
