The Real Science of Sport Podcast

Today we introduce the Science of Sport Spotlight, a category of podcast that we intend to use to round up all the big sports stories with a sports science angle, and then share those insights with you. Today, we discuss the news that transgender swimmer Lia Thomas has lost a case brought against World Aquatics' transgender guidelines at the Court of Arbitration for Sport. But it's not entirely as it seems - the case was dismissed because Thomas is not eligible to bring the case as Thomas is no longer a member of US Swimming. In this Spotlight episode, Professor Ross Tucker explains why that is frustrating for World Aquatics and other sports, and why the Thomas case would have made an interesting test in the court.Notes:Sean ingle's article on the decisionThe research paper by Senefeld that analysis Thomas' performance changes with testosterone suppression, alluded to in the showAnother research paper, on which I am a co-author, which explains why the IOC Guideline on the trans issue is so misguidedPatrons only: The discourse thread that mentions the Ultra cycling race won by a trans woman this past weekendYou can join the ongoing sports science conversation, and support our work, by becoming a Patron member at this link.That Patron membership gives you access to our Discourse channels, where like-minded enthusiasts discuss sports science and news

With 50 days to go to the Paris Olympics, it's all systems go for athletes, coaches, and media. Sean Ingle will be covering his 7th Olympic Games, and he joins us from Rome's European Track and Field Championships to talk about some of the themes we expect to make the news at these Paris Games. They include tech's pervasive and unavoidable influence on performance, a simmering feud in the world of anti-doping, and the evolution and relevance of the Olympic Games in the face of both external and internal pressures. We also present The Official Science of Sport surveys in which you get to vote for your favourite event of the Games, and our ambitious consensus project to classify the Olympic Sports by their physiological and psychological demands. A busy period of great sport starts here!Show notes:Here is where you sign up to become a Patron and get access to our awesome and informative Discourse communityThe Discourse page, for those who are already Patrons of the pod (you sign in with your Patron log-ins)If you want to join our survey to rate the Olympic sports for their athletic components, here is the link to the once-off surveyOur 'bracket' challenge to pick your most engaging, popular specific eventWe spoke of tech in cycling on the show, and here's an announcement from Team GB/Lotus about their track bikes for their Paris campaignHere's the paper with Kenenisa Bekele has a co-author, that recognizes that the new era performances, powered by super shoes, and aided by wavelights, need an asterisk alongside themFollow Sean Ingle on Twitter/X

Join host Mike Finch, co-host Prof. Jill Warner and Dr Dale Rae, Director at Sleep Science and a Senior Lecturer in the Division of Physiological Sciences at the University of Cape Town, as they discuss what good sleeping habits look like, what constitutes a good sleep routine, catching up on sleep, the effects of sleep deprivation and why sleep dictates mood regulation, body health and even weight gain.

Dr Nick Tiller literally wrote the book on it, The Skeptics Guide to Sports Science (available from Amazon HERE). As an exercise scientist at Harbour-UCLA in the US, columnist, writer and author, Tiller challenges many of the claims made by marketers and others, in the name of sport science. With the team Tiller delves into the details of questionable sports science, how to spot the good from the bad and the areas where sports science is most vulnerable.Follow Nick: Web: www.nbtiller.com Instagram: @nb.tiller X: @NBTiller

The team is joined by Professor Stuart Phillips from the Department of Kinesiology at McMaster University and one of the leading experts on resistance training. Phillips is the Director of the Physical Activity Centre of Excellence (PACE), the McMaster Centre for Nutrition, Exercise and Health Research and Lab Lead for the Exercise Metabolism Research Group. In this episode Phillips explains the amazing benefits of weight training, why even a little can reap big benefits for everyone and what sort of training suits best depending on your age, sport and goals.SHOW NOTES:Join us on Patreon for more content including access to our Science of Sport Discourse platform, and join the conversation!Follow our guest Prof Stuart Phillips on XStuart's recent paper on the coming of age of resistance training as a primary form of exercise for healthA previous article on Stuart's resistance training research from his universityA few of the specific papers on strength training that were discussed on the show:Resistance exercise load does not determine training-mediated hypertrophic gains in young menTraining for strength and hypertrophy: an evidence-based approachLow-load high volume resistance exercise stimulates muscle protein synthesis more than high-load low volume resistance exercise in young menEffects of once- versus twice-weekly eccentric resistance training on muscular function and structure in older adults: a randomised controlled trialInstagram handle for Avery Faigenbaum, Professor of Pediatric Exercise Science, who Stuart mentioned as a good source of information

Building on from our previous discussions on optimal fuelling for endurance exercise, in this episode we go deep into the details of why carbohydrates are the rocket fuel for our bodies, and how we can take advantage of metabolic agility and different fuel strategies to unlock performance gains. To do this, we are joined by Dr Jamie Whitfield, a postdoctoral researcher in exercise nutrition and an expert in muscle physiology and metabolism. We explore how your body ‘chooses’ whether to burn fats or carbs as fuel and which carbs it prioritizes as we change our intensity and diet. We discuss whether fasting or feasting before exercise is beneficial, and we learn whether ketogenic diets hinder or enhance exercise performance.SHOW NOTES:Jamie’s X account: @jwhitfieJamie’s page at the ACUThe article by Jamie and a former guest, Prof Louise Burke, responding to Prof Tim Noakes on Keto diets and performance. The entire point-counterpoint is available at the link: https://pubmed.ncbi.nlm.nih.gov/38485731/A research study that Jamie referred to that looked at how ingesting carbohydrates at different rates affected total carbohydrate use during exercise: https://link.springer.com/article/10.1007/s00421-022-05019-w

In this special episode we join an exclusive panel discussion - in partnership with World Rugby - to debate the future of the sport as it battles to find a balance between the welfare and safety of players and the enjoyment of the game by both participants and spectators. On the panel is Dr Eanna Falvey, World Rugby’s Chief Medical Officer, and former British & Irish Lions Team Doctor; Kate Zachary, the experienced American women's captain and veteran of two World Cups; Ugo Monye, an English rugby pundit/commentator and former rugby union player who played 14 times for England, 241 times for his only club Harlequins and played twice for the British & Irish Lions on their 2009 tour to South Africa; English Test player Sarah Bern, who was shortlisted for World Rugby’s Women’s Player of the Year award in 2019 and our very own co-host Prof Ross Tucker, who is also a Research Consultant and Independent Scientist with World Rugby.SHOW NOTES:The videos from the entire Welfare Week, not just those preceding this session, will be available on the World Rugby site soon. They're not out just yet, unfortunately, but check back here in the next few days for the specific links.

It's one of the hottest topics on our Discourse channel but can World Rugby's new law proposasl preserve the spectacle of the game while still ensuring player safety? The team dig into some of the changes being trialled and proposals for more changes.Plus ultra runners Camille Herron - who broke six world endurance running records on her way to a new women's six-day record - and Jasmin Paris - who became the first female to finish the legendary Barkley Marathon - have raised the question of how women compare to men in endurance sport. Is the gap closing?Plus why did a group of 26 independent scientists (including Ross) publish a paper to refute the IOC's framework and academic paper on transgender athletes?Support our work on Patreon HERE at and get free access to our Discourse channel HERE SHOW NOTES:Rugby rule changes on our Discourse group.https://scienceofsportpodcast.discourse.group/t/world-rugby-new-plans-for-the-game/1197/4Reassessing the use of the TMO in rugbyWorld Rugby wants to ­overhaul TMO protocol which has come under widespread criticism for bringing too many lengthy stoppages to the game. Women's Ultrarunning Discourse discussion on the Barkley marathonSean Ingle's article on Jasmin Paris' Barkley successTransgender PaperThe academic paper refuting the IOC's Framework and scientific argumentOur Discourse discussion on the paper and the issuesMore than 100 elite British sportswomen have told the BBC they would be uncomfortable with transgender women competing in female categories in their sport.
