It's a heart-to-heart on Spotlight today, as Gareth and Ross kick off by discussing a Discourse question about whether running marathons is bad for your heart? Ross describes five cardiac "risks" that have been documented, giving context and a bit of reassurance in response to theory that excessive endurance training is damaging to heart tissue. We then talk about maximum heart rate, and why it's an imperfect anchor for training prescription and a poor comparison between people. We shift from heart to brain to briefly discuss whether coaches should be sanctioned when players tackle poorly in rugby, and end off with a brief look at two teen phenoms competing in Australia last week, wondering whether their trajectories are inviting unreasonable pressure at too young an age.DiscourseAs always, Spotlight is inspired by your engagement in our Discourse community, and you can become a member by visting the Patreon site, and pledging a small monthly amount that gets you access and an opportunity to engage with, and learn from, fellow listeners.Show notesIan's question about heart risk from marathon running, and some excellent Discourse replies - Members onlyThe research paper on troponin elevation after marathons, which kicked off the Discourse discussion at the front of today's showGood insight and discussion on whether too much exercise is bad for you?Here's that article i mentioned where Tim Noakes punched some holes in the theory that marathon runners would be protected against coronary artery diseaseUltimately, sudden cardiac death in marathon runners is rare.

In this week's Spotlight, we swing the light from cycling to doping, via trans news updates and some success stories from our Discourse members. We kick off with a chat about whether we've been too obsessed with power numbers, and not talking enough about speed, as pointed out by Christoph Roodhooft of Alpecin's pro-cycling team. We discuss what it means to be an "economic cyclist", which allows Gareth to propose the concept of "physiological frugality", which we are 100% sure will take over from "durability" as the next-big-thing in elite cycling by 2027!We also chat briefly about positive fuelling experiences shared with us by Discourse members, who've managed to push their energy intakes up thanks to the experts we've heard from on the pod. We check in on some controversial topics, including the transgender athletes in sport debate, where a new paper, a legal decision and an imminent IOC election are all in the spotlight, and finally, we briefly discuss Shelby Houlihan's own words about her doping defence in an interview with Letsrun.com.Show notesAs mentioned, Discourse is our VIP Community where you can share bicarb recipes, tales of fuel success, and a whole lot more!
