A thought crossed my mind: Knowledge & confidence, and “feeblemindedness”

IMG_1531

Around 100 years ago, the world's leading scientists got together to discuss "eugenics", the idea that we could selectively breed "good stock" for the benefit of the human race. This happened openly, with the support of the USA's judicial system, and looks macabre and horrific in hindsight. It made me wonder about over-confidence, and knowledge, and how experts shouldn't ever profess absolute certainty, on anything.

Screen Shot 2017-03-21 at 10.16.07 AM

Nike recently unveiled the Vaporfly Elite, the shoe it has been working on to help it break the 2-hour marathon barrier. The shoe incorporates a "spring plate", and is claimed to have significant performance implications. I think the shoe, and the incorporation of spring-like devices in all shoes, should be banned for future credibility of performance. Here's why

The sub-2 hour marathon in 2017? Thoughts on concept

Screen Shot 2016-12-13 at 5.53.48 PM

Nike's announcement that they're backing three top marathoners to break the 2 hour marathon barrier in Spring 2017, is the latest installment in the sub-2 hype. Relevance and legitimacy aside, what would it take, product and course wise, to achieve? I look at shoes and downhill running to illustrate the concept of physiological barriers and how they might be shifted.

2016 publications: From the armchair to the site, via these journals

publication

Much of what you read here on this site is my attempt to translate the research I'm interested in, and which can be applied to the real world, in a way that makes it more "palatable" to you. This post, however, summarizes some of the "source" research, the scientific articles that I've had published in the last 12 months, for those wanting to see the academic side of the discussions we have.

Caster Semenya won the Monaco 800m in 1:55.33, at a canter, and is the surest bet for gold in Rio 2016. She's also the surest bet for controversy, and will kick start an explosive, aggressive debate. This post introduces some of the concepts, and addresses some issues around our approach to this difficult issue.

Hyperandrogenism and women vs women vs men in sport: A Q&A with Joanna Harper

Caster Semenya Rabat

Caster Semenya's likely gold medal in Rio is going to be one of the most controversial stories of the Games, if not the history of the Olympics. She is, unwillingly, the known image of a sex-verification controversy in sport, asking questions over whether a woman should compete against other women. In this piece, I interview Joanna Harper, an expert on matters of transgender science and performance, for her comprehensive views
