We have a news-heavy Spotlight for you this week, with stories from athletics, cycling and Rugby League to discuss. Shelby Houlihan's return from a doping ban has Gareth wondering about second-chances and forgiveness for dopers? Cycling's authorities met at the Cyclocross World Champs in Lievin and agreed to regulate the use of carbon monoxide and to prevent its misuse for performance enhancement. We talk about that decision and its details, and how it's a positive step, despite some recognized limitations. Cycling safety is also under the spotlight, with the tragic deaths of cyclists around the world a reminder of the perils of the sport, particularly during training.

Finally, Rugby League is considering a change to how players are sent off for high tackles, with a proposal to give yellow cards only when the player on the receiving end of the illegal tackle fails an off-field test indicating possible concussion. Proposed as a means to "get more consistency", Ross explains that if anything, it introduces a (for now) random, unpredictable outcome variable in the decision that will compromise consistency, and may detract from player welfare and behaviour change initiatives.

But first, we kick off the show with our Discourse-first birthday announcement, a thanks to all our fabulous followers, and then revisit last week's Spotlight on carbohydrate requirements to explain why elites need to fuel at rates the rest of us needn't aspire to emulate.

Former South African top-order batsman Gary Kirsten is one of the most respected voices in the modern game. After playing 101 Tests and 185 one-day internationals, Kirsten went on to a successful career as a coach. From 2008 to 2011 he coached India that included their win at the 2011 World Cup. Later in 2011 he was appointed coach of the South African team until August of 2013 and also had a brief stint with Pakistan in 2024, along with numerous coaching appointments in other formats including India's IPL. In this wide-ranging interview, Kirsten delves into some of the biggest issues facing the game: The threats facing the future of Test cricket, why the art of fast bowling is dying, the role of coaches at both school and international level and concerns over a proposed two-tier system in the global game.

Note: We are aware of a small technical issue where some sections of the pod skip or "jump". We are looking to sort this out in a future upload/version of the pod. Sorry about that!

In this episode, Simon Yates, carbohydrates and the applicability of sports science research to the masses are in our Spotlight. In an interview earlier this week, pro cyclist Simon Yates described a paradigm shift that has changed nutrition and training in the sport. Instead of five hour rides on "two eggs" and "water in the bottles" leaving him feeling exhausted, he talks about 120g/h of carbohydrates in training and racing leading to less fatigue, greater enjoyment, and significantly better performances. That's not new, of course - more carbs has been the name of the game for the elites for some time, as we've discussed in previous shows.

Now, Gareth and Ross explore the extent to which elite practice and behaviours should guide what the rest of us 'mortals' do, and whether the pendulum of advice has swung too far? To do so, we use a recent paper by Louise Burke and her team to explain that sports science research, often done on recreational or moderately trained athletes, often fails to add value to elite athletes. Conversely, we discover that what elites do is not necessarily directly applicable to the rest of us, and that while Yates and others demonstrate important principles of nutrition (yes, you need those carbs for harder training), we need to understand context and circumstances in order to understand exactly how to apply their behaviours to our own situations, and to get the specifics right. Ultimately, we may all be bound by the same (physiological) rules, but we're often playing a different game. We explain how to translate and apply research to practice, and vice-versa.

Plus, a brief look back at the Australian Open, how tennis analytics doesn't quite do justice to the 'adversarial' nature of the sport, and why players shouldn't be too fussed with perceived crowd and media hostility.

Richard Hales has spent the last 22 years fixing Royal Marines at the Command Training Centre Royal Marines (CTCRM) Lympstone in the UK and is the Clinical Lead within their bespoke Exercise Rehabilitation Centre. So he knows a thing or two about the role of physiotherapy in a pressurised physical environment. The team delve into the role of a physiotherapist in both prevention and recovery; explains how data drives much of the research, why old-school physio techniques are questionable and whether biomechanics make a difference in causing chronic injury.

Hales graduated with a Sports Science degree from Liverpool University in 1992 before qualifying as a Chartered Physiotherapist from Bath University in 1996.

Having chosen to specialise in musculoskeletal rehabilitation his roles have included six years as Physio with Exeter Chiefs Rugby Union Club, and clinical co-ordinator for Amputee rehabilitation within ‘Adventure Rehab’, as well as Out-Patient work in both the UK and New Zealand before joining the military.

He has just written a book about his time working with the Royal Marines entitled The NOD Fixer which is due out in Easter 2025.

Can we trust "experts" in the fitness and health industry? We put this question under the Spotlight this week, inspired by a combination of Gareth's fell running exploits and virus scare, his quest to replenish carbohydrates after racing, and a fascinating insider Discourse chat about the credibility of the fitness industry. How can fitness, health and sports enthusiasts know who to trust, and can they ever be assured of credible, effective advice from personal trainers and fitness influencers whose intentions may be good, but whose knowledge is not always where it needs to be?

A lot has changed since 2000 in sport but not everything predicted at the start of the Millennium has happened by 2025. So what may sport look like in 2050? Hosts Mike Finch and Prof. Ross Tucker - along with the Chief Sports Writer of The Guardian, Sean Ingle - look back at what was predicted in 2000 and what could happen 25 years from now. From age-defying world beaters to astonishing tech and the likely future and popularity of sporting events, sport looks set for some radical changes in the second quarter of this century.

Who were the superstars, and what were the unforgettable moments of 2024? Who failed to launch, and who exceeded expectations? What are your hopes for sport and sports science in 2025? We draw a spectacular sporting year to a close with a look back at the highlights, lowlights, newsmakers and big stories of 2024. In a somewhat tongue-in-cheek "Sporting Awards" show, Mike, Gareth and Ross pick out their winners and losers, and the achievements that got us talking and debating. Inspired by the contributions and nominations from our Discourse community, we make our selections in categories ranging from the Moment of the Year to the Biggest Anticlimax of the last twelve months, with sports science insights and the big sports science stories covered in between.
