• A Deeper Insider Look at Fatigue and Pacing / Why High Carbohydrate Intake Works - It's Not Fuel Depletion / A Heat Condundrum

  In this Spotlight, we pick out some of the sports science topics that our listeners are sharing in our Discourse community. You can become a Real Science of Sport Supporter here, and a small monthly pledge gets you access to the community that discusses today's, and many other, topics!(00:00) We begin with a look at some of the reaction to our most recent podcast on Endurance, and the Central Governor. Listener reaction and accounts of their experiences stimulate conversations about the hostilities and fights in academia, the difference between "belief" and "knowledge", failures of pacing leading to heat stroke, and how to recover from a pacing mistake when it happens in your races and training. We also learn about how physiology, for many years, views performance through a 'failure' lens, rather than regulation, and what this means for how we understand training and performance.(46:09) A new research study has again confirmed that high carbohydrate intake is the way to go, improving our running economy and unlocking potential performance gains similar to those of super shoes. We link pacing and regulation to this paper by pointing out that carbohydrates are not working by delaying fuel depletion, or sparing carbohydrates, but rather changing exercise intensity and our ability to run higher paces for longer.(57:53) Our Supporters Club have also been sharing thoughts about the challenge of endurance sports in the heat, which affects not only body temperature, but also fuel use (more carbs) and compromises carbohydrate delivery to the muscles. A triple challenge, confirmed by a new study that shows that we tolerate and extract fewer carbs in the heat.And Finally (1:03:15), Ross is planning his own heat challenges, having entered a mountain bike race in the peak of South Africa's summer. With temperatures expected to soar above 40C, heat adaptation and fuelling will be tested, and he discusses his general approach and promises to share more in the coming weeks! Hosted on Acast.

• Olympic Track and Field Schedule Surprises / Risk of Cardiac Events When Watching Sport / Rugby's Calendar Challenge

  Become a member of The Real Science of Sport Supporters Club to show your support and have your say. A perk of membership is Discourse, our community that chats about training, sports science, physiology and news.Show notesA midweek whip around the world of sport, with some sports science and management insights on stories making headlines this week. We cover:The LA 2028 Olympic Track and Field programme was announced last week. It features three 100m races on one day for the women, and no option for a 400m/400m hurdle double, are among the surprises. We discuss the effects on athletes and the missed opportunitiesTriathlon's T100 series was plunged into chaos with miscounted laps, result changing decisions, and even a vote on whether rules were applied to the satisfaction of athletes. We discuss the fiasco in DubaiBoxing continues its (d)evolution to WWE, with a fight announced between Anthony Joshua and Jake Paul. A gimmick, for sure. Too dangerous? We discussWorld Rugby announced a new calendar for 2026, aimed at giving more relevance and meaning to Tour matches. The schedule has pros and cons, creating a travel load for teams that will require some accommodation for player welfareAnd finally, cardiac events among spectators at last week's ATP Finals are the trigger for a short discussion about the risks of WATCHING sport, with some interesting studies showing how risk increases when people are invested in the resultOther linksThe paper studying cardiac arrests at Gillette StadiumThe cardiac event risk is slightly higher in football in the NetherlandsLosing, but not winning, a Superbowl increases the risk of cardiovascular death Hosted on Acast.

• Will the Olympics Finally Protect Women's Sport? / Anti-Doping Antagonism and The Enhanced Games / Bracy-Williams Banned

  Support us on DiscourseDiscourse is our "sponsorship", our sole source of income. But it's way more than that - it's a community of experts and enthusiasts who share knowledge on everything sports science related. Oh, and it also inspires these Spotlight shows. To become part of all that, become a Patron of the site and join the conversationIn today's show, we run the Spotlight over news stories from the past week, including:4:32. The International Olympic Committee are reportedly going to move to protect women's sport by preventing trans identified males and athletes with DSDs from competing in women's sport. Will this come to pass? We discuss reports on the shift in policy, and raise some key questions. Will the IOC compel screening for sex and testing for advantage? Will they include DSDs in the policy? Will sports be obliged to comply, or remain able to govern eligibility as they please?18:32. Antagonism in antidoping continues, with shots fired between WADA and USADA, this time over The Enhanced Games. WADA think USADA should be doing more to stop the Games, but USADA say they have no authority to act. We discuss their remits, and the damaging mistrust that now exists between them. We also talk about the threat of the Enhanced Games, and USADA's perceptions of why athletes are joining "the doping Olympics"28:59. Staying on doping, US Sprinter Marvin Bracy-Williams has been banned for 45 months. The 2022 100m silver medalist got a reduced sentence for co-operation, and we wonder what he shared with authorities, and whether the investigative approach will produce future sanctions?34:09. Chinese teen prodigy Yu Zidi has continued her ascent to the summit of swimming, with a 200m individual medley record that puts her into the conversation for future world and Olympic medalists. We wonder what her trajectory looks like, using a previous Chinese teen phenom to offer a dose of reality.42:18. And Finally, tennis, with another "battle of the sexes" match in December between Aryna Sabelenka and Nick Kyrgios, with a few modifications to neutralize men's power. We talk about those changes, then finish up with a quirky look at the men's tennis rankings that reflect the extraordinary dominance of the current top two.LinksIOC moves to protect women's sportWADA reckons USADA can do more to stop The Enhanced Games from proceedingUSADA does not agree, and respond with some hostilityUSADA statement on the 45 month ban for Marvin Bracy-WilliamsYu Zidi's 200m medley performance sending waves into swimmingKyrgios is confident ahead of the gimmicky battle of the sexes match Hosted on Acast.

• The Story (and Science) of Endurance

  Endurance has been one of the most hotly debated topics in sports science for over three decades. From early research in the 1930s to the ground-breaking 1996 address by Prof. Tim Noakes to the American College of Sports Medicine, understanding the principles of what keeps the body going during prolonged exercise is more complex than you think. In this episode, Mike and Ross take a look back at the often controversial history, Ross's own research journey and experience with Noakes and find out if it really is possible to push beyond our own endurance limits.Support us on DiscourseDiscourse is our "sponsorship", our sole source of income.

We talk pacing micro-adjustments, late end spurts and misjudged fatigue and sprint finishes17:44 Joe Klecker ran a 2:10 in NYC, but caught our eye because he planned to take in 175 g per hour of carbs in the form of almost 3 L of fluid. An insanely high intake, but one that he discussed in a recent podcast with The Coffee Club. We talk about that strategy, his experience of it, and how it fits in the new carbohydrate paradigm35:22 WADA are making moves to consider banning Ozempic and drugs like it. Gareth and Ross discuss whether WADA are over-reaching, or whether they need to pay attention to the possible impact of the weight loss drug in sport, with Ross expressing doubts that it has long term performance benefits given how it works44:53 Elite athlete Laura Hottenrott recently raised concerns about the frequency of blood testing doping controls she has been subjected to.
