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.
SHOW NOTES
Stian Angermund Doping Case
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.

This week World Rugby announced that they will be including head accelerations measured by smart mouthguards into the sport's head injury assessment protocols used at the top level of the game to help identify potential head injuries during a game. This is how they work, why the tech could be a game changer and the challenges facing their adoption.
