Episode 18 - Atrial fibrillation in cyclists, Interview with Prof Gerry McCann

Episode 18 - Atrial fibrillation in cyclists, Interview with Prof Gerry McCann

In this episode I speak to Prof Gerry McCann who is a heart specialist with a subspecialist interest in MRI scanning; he conducts experimental research in people to better understand heart disease and clinical trials to assess the optimal investigation strategies and treatments for patients with, or at risk of developing, heart disease.

Professor McCann is the Cardiovascular theme lead for NIHR Leicester Biomedical Research Centre, the immediate past-chair of the British Society of Cardiovascular MRI research group, lead of the PhOSP-COVID cardiovascular working group and East Midlands Cardiovascular Clinical Research network.

Gerry and I actually studied together at Glasgow University and in this interview we discuss atrial fibrillation, or AF as it is known, as it relates to cyclists. There is some evidence that high volumes of endurance training like cycling may be a contributory factor the the development of atrial fibrillation therefore we discuss exactly what it is, what are the specific risks and potential treatments.

Episode 17- Interview with Prof Ron Maughan, everything nutrition

Episode 17- Interview with Prof Ron Maughan, everything nutrition

Ron Maughan obtained his BSc (Physiology) and PhD from the University of Aberdeen, and was based in the Medical School there for almost 25 years before moving to England. He is now semi-retired but is still a Visiting Professor in the School of Medicine at St Andrews University. He spent much of his career trying to understand the physiological and metabolic responses to exercise and the nature of fatigue, but has included many digressions along the way. He chairs the Nutrition Working Group of the Medical and Scientific Commission of the International Olympic Committee. He is a director of the IOC Diploma programs in Sports Nutrition, Sports Medicine, and Sports Physical Therapies. He organised the IOC Consensus Conferences on Nutrition in Sport in 2003 and 2010, the FIFA/F-MARC Consensus Conferences on Nutrition in Football in 2005 and 2011, and the IAAF Consensus Conference on Nutrition in Athletics in 2007. More recently, he organised the 2017 IOC Consensus conference on Dietary Supplements in Elite Sport. He has published extensively in the scientific literature and is author or editor of a number of books on sports nutrition and exercise biochemistry. Not only that he has inspired, educated and supported a large number of sport scientists throughout their career, myself included. In this episode we discuss a number of the core themes in sports nutrition and debunk a few myths. In particular we talk about one of his more recent publications. The 'IOC consensus statement: dietary supplements and the high-performance athlete'. In particular to emphasise on of the key findings that "Supplements claiming to directly or indirectly enhance performance are typically the largest group of products marketed to athletes, but only a few (including caffeine, creatine, specific buffering agents and nitrate) have good evidence of benefits."

Episode 16 - Cycling into old age- Royal Academy of Octogenarian Cyclists

Episode 16 - Cycling into old age- Royal Academy of Octogenarian Cyclists

In this episode I explore the topic of ageing and cycling, an area that I have researched extensively myself. But in this episode I interview Ray Maranette who has established a Facebook group called the Academy of Octogenerian Cyclists that can now boast after only a short time in existence, over 1.1k members across the globe. While this interview is a departure from my usual interviews of research scientists it is a very good reminder that cycling has a huge amount to offer all of regardless of our age. The fact that The Academy of Octogenarian Cyclists has very quickly grown a strong membership from a wide range of backgrounds from the pure leisure cyclist to ex professional riders I suppose gives testament to the fact that regular cycling can help you stay fit healthy and intellectually alert into later life.

Episode 13 Dr Mia Burleigh - Interactions between diet(nitrates) and oral bacteria in the regulation of human health

In recent years there has been a significant interest in using nitrate supplements to enhance athletic performance with sports nutrition companies producing beetroot and cherry supplements to try and increase our nitrate intake.

In this interview with Dr Mia Burleigh I discuss why nitrate  supplementation might be good for cycling performance and then go on to discuss her work which also looks at the health benefits of nitrate supplementation and why this may be particularly important for the oral health of athletes who would regularly consume large volumes of carbohydrate drinks during exercise.

Episode 12 - Interview with David Smith MBE

Episode 12 - Interview with David Smith MBE

<ul>
<li>David Smith is a remarkable athlete and individual who from a young age had an overwhelming desire to be an elite athlete and compete at the Olympics. Things did not start well as he was born with club feet which required an operation, requiring him to have to learn to walk again. Not really the start of a promising career as an elite athlete or Olympian. Not only that he would go on to have to endure medical misdiagnoses, followed by tumours, blood clots, strokes and paralysis, a life of agonising pain and multiple further life threatening operations.</li>
<li>Despite all of this David's story is one or remarkable determination and resilience which has resulted in a career as an elite athlete and a successful one at that as a 2x World Champion and London 2012 Gold medalist. These success coming as a member of the Rowing Paralympic team in the legs, trunks and arms adaptive mixed coxed four.</li>
<li>To summarise he has to date had to endure 6 operations on the tumour in his neck and has come close to not surviving those operations on several occasions. On each occasion he has had to learn to walk again. After his 5th operation he is now significantly paralysed down his left side but this still does not stop him riding his bike. Yes having dabbled in several sports, winning Olympic Gold he says that his true passion is cycling and he loves the freedom that the bike gives him.</li>
<li>This interview covers his life story, all of the ups and downs to where he is now, training on his bike 14-16 hours a week trying to build up his strength with an eye to the UCI World Championships in Glasgow in 2023.</li>

Episode 11 - Technical Innovation 3, Another first for SRM with the X-power Pedal

Episode 11 - Technical Innovation 3, Another first for SRM with the X-power Pedal

In this episode I had the great pleasure of chatting to someone who I have known for about 25 years and has had a profound influence of cycling over the last 30 years. Uli Schoberer is the inventor of the first power cranks and founder of SRM. Since then SRM cranks have been considered the gold standard of power measurement and thus have been seen at world championships and in the pro-peleton for the last 25 years transforming our understanding of cycling performance. In the interview Uli gives as great historical account of the development of SRM right up to the most recent product the X-power pedals, SPD mountain bike pedals - the first mountain bike pedals to the market. Another first for SRM.

Episode 9 - Technical Innovation 1 - Shokbox bike box

In a slight departure from our normal format we are introducing a new technical innovation series  where we will bring interviews from  different inventors of technical innovation in cycling. On the Cycling Science Podcast we do not do simple endorsements or marketing of new cycling products products and we only interview people if they are doing something really innovative, breaking the mould or bringing something that is first to market. 

First we have Shokbox (www.shokbox.co.uk) invented by Martin Greene, this is a very interesting story where Martin recognised from personal experience that many of the bike boxes on the market had significant flaws and decided to do something about it. Martin tells us about the thought process that went into designing his new bike box by improving on all of the key important features that can be problematic in packing and transporting your bike in a bike box. 

For each of the new Technical Episodes I will post a longer article on the website www.cycling-science.com if you would like a bit more detail.

Episode 7 - Interview with Dr Shawn Bearden, Science of Ultra

Episode 7 - Interview with Dr Shawn Bearden, Science of Ultra

I had the great pleasure to interview Dr Shawn Bearden, who was one of my inspirations to create this podcast. Shawn has his own super successful podcast 'The Science of Ultra', where he conducts interviews, has a coaches corner and some individual information about ultra trail running.  He is a former soccer player who, after studying at Florida State University then became a professor of physiology at Idaho State University, turned to running in what he called a mid life crisis. Although this was not just the run of the mill running this was the really long 'ultra'' stuff.  This episode starts by getting a bit more background on Shawn and why he decided to start his podcast. We then try to compare his work as an exercise physiologist, coach and now podcaster on ultra running to the world of ultra cycling.

I would certainly recommend that even if you are not a runner that you have a listen to Shawn's podcast as there is some great material there that is relevant to any athlete or coach.

Episode 6 - A successful riders perspective of Cycling Science

Episode 6 - A successful riders perspective of Cycling Science

In the last episode I discussed the translation of research with Dr Laurent Bannock and for this episode I wanted to explore what it is like for a successful rider and how science could guide their training.

The rider is Andy Bruce who I have known since he took up cycling in 2011. In this short time he has made fantastic progress so that in 2019 he managed to win one of those stripey jerseys that we would like to have by becoming the World Masters Points Race winner. I think as well as his progress I do marvel at how Andy manages to fit in all of his training around a busy job that involves a lot of international travel.

Anyhow as you see below his palmares speaks for itself ;

2019 Wins/Medals:

World Masters Points Race (M45-49) Championship - Gold

World Masters 3k IP (M45-49) Championship - Silver

British Masters 3k IP (M45-49) Championship - Gold

British Masters Road Race (M45-49) Championship - Silver

Scottish Veterans 3k IP Championship - Gold

Scottish Veterans Road Race Championship - Gold

Scottish Senior 4k Team Pursuit Championship - Gold

Scottish Senior Team Time Trial Championship - Gold

Scottish National Olympic Time Trial Team Championship - Gold

Previous Significant Podiums:

British Masters Circuit Race Championship - Silver (2017)

Scottish Veterans 3k IP Championship - (Gold in 2018, Silver in 2017)

Scottish Veterans Road Race Championship - (Gold in 2016, Silver in 2017)

Scottish Senior Circuit Race Championship - Bronze (2018)


So the podcast follows his journey to the present day trying to extract what leads to success at this level and the lessons that he has learned along the way.

Episode 5 - Translation of Research to Practice

Episode 5 - Translation of Research to Practice

A joint podcast with Dr Laurent Bannock, Institute of Performance Nutrition (www.theiopn.com), 'We do Science Podcast'. Both Laurent and I have an interest in the translation of research into practice and how practitioners, coaches and athletes can first of all access appropriate information but also how the latest research influences practice. We discuss how research findings can be difficult to interpret and therefore are easily misinterpreted and the key reasons why findings might be misinterpreted. Over the last 10 years there has been a very significant increase in research publications across all of the sport sciences and even specialist researchers find difficult to keep up thus it is even more difficult for practitioners, coaches and athletes to keep up. It is also difficult for these non-researchers to put any single research finding into context against all of the preceding research. It can also be said that practitioners and coaches have a key role in highlighting potential areas of research, ensuring that the research that is conducted attempts to answer relevant practical issues.

We suggest that accreditation of practitioners combined with a learning mindset are critical to ensure that practitioners provide evidence based practice. Researchers have a key role in communicating their findings in a way that is accessible and practical to practitioners. 


We refer to two recent publications both of which outline some of the key issues.

Episode 4 - Crash Bang

Episode 4 - Crash Bang

Episode 4 - Crash Bang

In this episode we discuss a recent paper on acute injuries in mountain bikers published in the Journal of Sports Science and Medicine. Injuries are always present in mountain biking so this paper tries to provide a bit more detail comparing amateur and elite riders.

Stoop, Rahel, Erich Hohenauer, Thomas Vetsch, Tom Deliens, and Ron Clijsen. 2019. “Acute Injuries in Male Elite and Amateur Mountain Bikers: Results of a Survey.” Journal of Sports Science and Medicine 18 (2): 207–12.

Appropriately also included is an interview with Dr Michale Bottlang the inventor of the Bontrager Wavecell helmet. The revolutionary helmet design which is designed to reduce the rotational forces potentially experienced by cyclists in a fall.

The interview gives a great insight to the science behind the development and testing of the wavecell helmet. If you are interested in a more visual representation of the benefit of this technology then this video (https://youtu.be/iilGcMeKkuc) using an egg as a representation of your brain gives a very clear image of the improvement that wavecell can make.

In our news section we talk about:

  • the recent press that eBike users are just as active a normal bike users
  • brief discussion on a new paper looking at the long term of high dosage of vitamin D
  • the recent revelations from Jani Brajkovic about the prevalence of eating disorders in the pro peleton
  • the true story of the cyclist with the highest-ever VO2max
