Paris 2024: How to Make an Olympic Athlete
5 juli 2024 · 1 uur 26 min
Mark Coogan has been there, done that and got the t-shirt. As a former track athlete, sub-4 minute miler, Olympic marathoner and author of the book 'Personal Best Running', Coogan is passing on his wealth of talent to some of America's top track and field stars with much success. In this discussion, Coogan talks candidly about the process of developing Olympic-level elite athletes, how to spot elite-level talent, what makes a champion athlete, how to train athletes for events as important as the controversial American Trials and the Olympic Games and whether the sport is in a good place globally. Coogan works in the engine room of top-class athletics and his insights will inspire all levels of sports people. Lees meer

Science of Sport Spotlight 4: Shining a Tour de France Light On Exercise In The Heat
3 juli 2024 · 36 min
In this Spotlight, the team discuss exercise in the heat, using the challenging conditions and travails of Mark Cavendish and others in the Tour de France's first two stages as the catalyst. We explore why athletes 'fail' in the heat, and how the brain pulls a physiological ripcord to protect us when we either don't pace ourselves appropriately, or can't lose the heat we need to in order to avoid critical hyperthermia. We also briefly assess the state of the Tour's yellow jersey battle, where the first shots were landed by Pogacar on the Galibier in yesterday's Stage 4. But will they be decisive, and how likely is Vingegaard to bounce back and improve as the race progresses? Lees meer

Science of Sport Spotlight 3: TDF 2024 Preview
27 juni 2024 · 28 min
The Tour de France begins Saturday and in this Spotlight, Ross and Gareth gaze into their crystal balls to discuss whether Jonas Vingegaard, the two-time defending champ, can recover from his April accident to challenge race favourite Tadej Pogacar? They explore how his injuries will have set back his preparation, and the challenges he'll have faced to balance recovery with adapting for the demands of a Grand Tour. They also explain how his 'durability' may be compromised, and how Pogacar may look to exploit this tactically, to kill the contest in Week 1. Add in some speculation and predictions we both hope are proven incorrect, and you have a TDF teed up for discussion and debate! Lees meer

Durability in cycling, as discussed on the show
A field study of durability in elite cyclists, showing a 3% (average) drop in 20 min TT power after a fatiguing bout. Note that the fatiguing bout used (10 kJ/kg/hr) is equivalent to an easy-to-moderate mountain day in the Tour. UAE will want rivals to do a LOT more work than this before attacking in the final 20 minutes
A nice study looking at how fatigue affects the power-duration curve in elite cyclists. This shows that World Tour riders are more "durable" than Pro Tour riders, and that the greater the work before "the test", the greater the decline. Again, a cue for a rider who wants to win the Tour to put his rivals under pressure before the final climb

The Real Science Of Hydration During Exercise
25 juni 2024 · 1 uur 19 min
Dr Tamara Hew-Butler is the Queen of Hyponatremia (@hyponaqueen on X). What's hyponatremia, you may be wondering? It is a condition that is far more dangerous than dehydration, and which can develop when we drink too much fluid during exercise, with potentially lethal and often tragic consequences. We have been conditioned to fear the health and performance risks of dehydration during exercise, to believe that we cannot afford to lose fluid, and that by the time we are thirsty, it's too late. But Hew Butler, a world authority on fluid requirements during exercise, is here to set the record straight, to explain how exquisitely our bodies regulate our sodium and fluid levels, and why we can and should trust our physiology instead of the marketing messages of sports drinks and water companies. This is an episode that will challenge beliefs, and set the record straight on exercise hydration. Lees meer

Science of Sport Spotlight 2: Kenya's doping induced credibility crisis
20 juni 2024 · 29 min
Kenyan athletes are being banned, literally, by the hundreds. The country that produces many of the world's outstanding distance performers has a huge credibility crisis. It is clear that doping is widespread, but frustratingly, despite dozens of athletes being caught and banned every month, we are no closer to identifying how what have been described as "sophisticated doping regimes" are being managed and delivered to many of the best Kenyan athletes. In this Spotlight, the second episode of the Series, Ross and Gareth talk about the extent of the problem, the challenges faced by authorities who are casting their own spotlight on Kenyan running, and the shadow that sadly looms over Kenyan medals and records.

Science of Sport Spotlight 1: Lia Thomas loses case against World Aquatics
13 juni 2024 · 14 min
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.

INTERVIEW: How to Fuel For Maximum Endurance Performance
19 april 2024 · 1 uur 20 min
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. Lees meer

The Man Who Cycled the Globe: Adventurer Ron Rutland from Paris
8 september 2023 · 1 uur 30 min
Ron Rutland arrived in Paris on 7 September 2023, concluding the fourth leg of a remarkable (and not always planned) journey that has spanned a decade and four Rugby World Cups. Beginning in 2013, Ron rode from Cape Town to London via every country in Africa, then London to Tokyo, Tokyo to Auckland, and Auckland to Paris (via South and North America). It's a journey that has covered over 100,000 km, crossing 115 countries on six continents. In between, he caddied the longest hole of golf every played across Mongolia. Ron has seen and experienced it all - mudslides, heat, illness, adopted dogs, bus accidents, Himalayan and Andean passes, 100km climbs and even longer descents. He and Ross sit down in a hotel coffee shop in Paris to talk about his cycling journey around the world, fitness gains, calorie deficits, see-food diets, and the challenges overcome, lessons learned, and life philosophies developed along the way.

Woodpeckers do get concussed, and what this means for the Q-Collar and brain injury prevention
29 augustus 2023 · 1 uur 32 min
The Q-Collar is a device that is promoted to prevent concussion and "protect the brain during repetitive head impacts", and has been spotted around the necks of athletes in a number of sports, ranging from cricket to football. But do these claims and promises stand up to scientific scrutiny? Is there a sound biological rationale for the claims? Should parents, athletes and coaches explore and use devices such as this to prevent brain injury? Lees meer
In this episode, Ross explores the answers to the above questions with Prof James Smoliga, professor of Public health and community medicine at Tufts University. Prof Smoliga puts an intense and in-depth scientific microscope on the claims, and concludes that there is no quality evidence in support of concussion and brain health claims, and that the foundational premise on which the product rests is flawed. We also learn that woodpeckers DO show signs of brain injury, that studies linking altitude to protection against concussion are grossly exaggerated and misinterpreted, and, humorously, that NFL teams with animal mascots are less likely to see concussion that teams without animal mascots.
