The Real Science of Sport Podcast

• Spotlight: The Science of Improving Human Performances / Technological Advances in Sport / Talent Scouting Through Zwift

  On today's Spotlight, we ask why runners are racing faster than ever? The same could also be said of cyclists, and we use an intriguing article by Amby Burfoot to explore and discuss the possible contributors, ranging from super shoes to the "Bannister effect". It leads us back to ground we've covered before (shoe tech, carbs), some areas we have yet to cover in detail (bicarbonate), and down some dark alleys that may contain the future (and possibly present) of doping methods.We also talk about technology in sport, and about which sports have seen the biggest, fastest leaps as a result of innovation, taking a quick tour of some other devices that have 'recalibrated' sporting performances and human limits.Finally, we discuss some of the science and performances in the Zwift Academy 2025, the latest iteration of a competition to identify and recruit aspirant cyclists into two professional cycling teams. We explore the tests used on the show, their value, and how hugely confounded the talent prediction is, even in a sport as measurable as cycling.Show notesAs mentioned, Discourse is where it all goes down, and here's where you click to become a member for a small monthly donation.

• Spotlight: A Women's Sub 4-minute Mile? / A Tale of Textbook Heat Adaptation

  In this Spotlight, Ross and Gareth become "bros" to discuss and critique a recent paper that forecasts a sub-4 min mile in women (specifically, Faith Kipyegon) if drafting strategies were improved. Ross explains his skepticism and reaction to straw man arguments in media about the paper, and the framing of the seven second improvement required as a "mental barrier". This ushers in a new segment for the show, "Grinds my Gears!".We also learn from a Discourse member, @pauliuspeciura, about how to execute a textbook heat adaptation strategy for a race he participated in recently. We talk about the physiology of heat adaptation, and how to implement a downscaled, but necessary approach to heat in your next race. We also briefly touch on two bits of news, one concerning an increasing lack of physical activity in children in the UK, and other a peculiar, though not unique, explanation for doping contamination in the recent case of triathlete Imogen Simmonds**Ross mentioned a USA Sprinter who was cleared of a positive drug test after using "passionate kissing" as a defence. That was Gil Roberts, not Derrick Brew as mentioned (article link below). Roberts, incidentally, got cleared of this positive result in 2017, but then had another doping violation in 2022 (16 month ban) and then another in 2023, and is now serving an 8 year ban!Show notesSpotlights are inspired by Discourse, and then the discussion continues there after!

• Rethinking Polarised Training with Dr Stephen Seiler

  Dr. Stephen Seiler is arguably the world authority on endurance training, and popularized the concept of polarized training. But a new paper has revealed some fresh insights into training polarization which suggest that the training structure may only be suitable for certain types of athletes. Enjoy this deep dive into one of the most-discussed endurance topics as we break down the theory, look at the results of this ground-breaking systematic review, discuss how the results can inform training protocols and what future studies are needed. Seiler is an exercise physiologist and Professor of Sports Science from the University of Agder in Norway.SHOW NOTESTHE PAPER ON Training Intensity Distribution Intervention will Produce the Greatest Improvements in Maximal Oxygen Uptake and Time-Trial Performance in Endurance Athletes?

• Spotlight: World Records Galore as Running's Recalibration Resumes / A Final Jannik Sinner Discourse

  This week's spotlight turns to the indoor tracks and roads of the world, as we discuss the continuing recalibration of running performance. Every USA Men's Indoor distance record was broken in the course of a week, with two world records among the performances. One of those world records didn't last the week, as Jakob Ingebrigtsen broke it in France. Then on the roads, Jacob Kiplimo took the half marathon into a new galaxy with a sub-57 performance. The two-hour marathon is now clearly within reach. Gareth and Ross discuss those performances, and inspired to some Discourse, look back at a 2008 paper that analyzed race-horses and greyhounds to make predictions about how fast humans can still run. We check in those predictions to discover how shoe tech has moved some events ahead of the curve.We also shine one last Spotlight on the Janik Sinner three month ban, elaborating on a few matters that arose since our previous emergency Spotlight, and explain why some of the vilification of anti-doping's process may be unwarranted, and in some instances (Tim Henman!) completely detached from reality!Join DiscourseFor more conversation and insight, join our Discourse community where fellow listeners, experts and enthusiasts offer thoughts and opinions on this issue, and many more sports science topics.

• Can You Trust Your Sports Watch?

  Dr Joe Warne is a former international athlete and the key instigator of the Sports Science Replication Centre at the Technological University in Dublin. Having also worked as a performance coach Warne has spent hours both testing and working with modern tech devices with a key interest in finding out how reliable and trustworthy the data is. In this interview, the team discusses the metrics you can best trust, how to interpret the data you get correctly, and what the future of wearable tech and exercise data could be.
