Dr Nick Tiller literally wrote the book on it, The Skeptics Guide to Sports Science (available from Amazon HERE). As an exercise scientist at Harbour-UCLA in the US, columnist, writer and author, Tiller challenges many of the claims made by marketers and others, in the name of sport science. With the team Tiller delves into the details of questionable sports science, how to spot the good from the bad and the areas where sports science is most vulnerable.

The team is joined by Professor Stuart Phillips from the Department of Kinesiology at McMaster University and one of the leading experts on resistance training. Phillips is the Director of the Physical Activity Centre of Excellence (PACE), the McMaster Centre for Nutrition, Exercise and Health Research and Lab Lead for the Exercise Metabolism Research Group. In this episode Phillips explains the amazing benefits of weight training, why even a little can reap big benefits for everyone and what sort of training suits best depending on your age, sport and goals.

A few of the specific papers on strength training that were discussed on the show:

• Resistance exercise load does not determine training-mediated hypertrophic gains in young men
• Training for strength and hypertrophy: an evidence-based approach
• Low-load high volume resistance exercise stimulates muscle protein synthesis more than high-load low volume resistance exercise in young men
• Effects of once- versus twice-weekly eccentric resistance training on muscular function and structure in older adults: a randomised controlled trial

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.

In this special episode we join an exclusive panel discussion - in partnership with World Rugby - to debate the future of the sport as it battles to find a balance between the welfare and safety of players and the enjoyment of the game by both participants and spectators. On the panel is Dr Eanna Falvey, World Rugby’s Chief Medical Officer, and former British & Irish Lions Team Doctor; Kate Zachary, the experienced American women's captain and veteran of two World Cups; Ugo Monye, an English rugby pundit/commentator and former rugby union player who played 14 times for England, 241 times for his only club Harlequins and played twice for the British & Irish Lions on their 2009 tour to South Africa; English Test player Sarah Bern, who was shortlisted for World Rugby’s Women’s Player of the Year award in 2019 and our very own co-host Prof Ross Tucker, who is also a Research Consultant and Independent Scientist with World Rugby.

It's one of the hottest topics on our Discourse channel but can World Rugby's new law proposasl preserve the spectacle of the game while still ensuring player safety? The team dig into some of the changes being trialled and proposals for more changes.

Plus ultra runners Camille Herron - who broke six world endurance running records on her way to a new women's six-day record - and Jasmin Paris - who became the first female to finish the legendary Barkley Marathon - have raised the question of how women compare to men in endurance sport. Is the gap closing?

Plus why did a group of 26 independent scientists (including Ross) publish a paper to refute the IOC's framework and academic paper on transgender athletes?

Is the field of sports science facing a credibility crisis? According to guest Dr Joe Warne, key instigator of the Sports Science Replication Centre at the Technological University in Dublin, most of the research done in the field is unreliable. So what is the true picture, how can studies be done better, what role do journals play in ensuring better standards and how do consumers discern the good from the bad?

Knowing how to measure and train close to your VO2Max may lead to big performance gains. But what is VO2Max and what's the best way to use it? We also discuss the latest developments around rugby's smart mouthguard and the announcement by World Athletics that they are trialling a new way of measuring the long jump which involves a take-off zone rather than a take-off mark. And no, it's not an April Fools joke!

Can you make your own sports drink and what would be the right mix? Here's what to look for. The team also tackles (see what we did there!) the use of smart mouthguards in rugby, whether trail star Stian Angermund was really guilty of doping, why parkrun has removed some of its records from its website and if the controversial Enhanced Games has any chance of succeeding.

Reigning world short-course trail running champion Stian Angermund says he is innocent and “utterly bewildered” after testing positive for banned substance chlorthalidone after winning the 55km OCC event at the Ultra-Trail du Mont-Blanc for the second time last year.
