  • Great power, great responsibility. Less power, greater speeds

    sportsscientists.com 22 Jul '15, 7am

    “With great power comes great responsibility”, the Spiderman quote invoked when Sky revealed Chris Froome’s power data from his victory in the Pyrenees last week. Only problem – according to the data, with LESS power, came greater speeds, and something didn’t quite add up. Or many thi...

    There’s been much talk of how physiological data – a VO2max – would validate or refute cycling performance. The reality is, as usual, a little more complex than this. My take, some illustrative examples of the concept, and suggestions for how performance, physiology & biology can work...

  • Comparative and longitudinal physiology

    sportsscientists.com 21 Jul '15, 7am

    So one of the ‘moving parts’, VO2max is known, and so it reduces the assumptions we must make in order to illustrate some other concepts. Let’s work on the assumption that Pinot has an efficiency of 23%. This would be reasonable for a cyclist, and even generous for one with such a hig...

  • Semi-transparency, smoke, mirrors and an illustrative case

    sportsscientists.com 20 Jul '15, 10pm

    Amidst all the talk of transparency in the Tour, Sky announced that they may publish “a few” outcomes, like average power output and average cadence from a stage. Some quick thoughts on this below: Top 1. All or nothing. Not quite, but there’s power in numbers it makes little sense to...

  • Tour de France 2009: Contador VO2max

    sportsscientists.com 21 Jul '15, 9am

    What we should rather do, and I hope can be done after this Tour, is to look at the average of all the major climbs – Arcalis, Verbier, Col de Colombiere, Col de Ronne, and see how the power output goes on average. Why? Because doping’s biggest impact may not be on the single performa...

  • Long live transparency - the data video controversy

    sportsscientists.com 14 Jul '15, 5pm

    The first rest day of the Tour de France produced, as usual, some off-the-bike stories, but in 6 years of covering the race, I can’t recall such a bizarre sequence of events as this one. About five days ago, Antoine Vayer, he who provoked Brailsford into calling performance analysis “...

  • Day 1 in the mountains: One more pixel, context & mistrust

    sportsscientists.com 14 Jul '15, 7pm

    I can’t stress enough – today’s mountain finish, and the estimated 6.1 – 6.2 W/kg produced by Chris Froome for 41 minutes (even though the attack only really came in the second half) is not an isolated reason for skepticism about cycling. Such skepticism was inevitable, and the ride w...

  • Specialization, training volume and talent development

    Specialization, training volume and talent development

    sportsscientists.com 22 Jul '15, 5pm

    Some children do train harder when very young – this may be due to parental influence as described previously, or it may be because the child enjoys the sport at a young age (between 9 and 15, that is – you can go younger, but then there are other issues I won’t go into here). Whether...
