    Cheers Matthew - I'm after that article specifically, but will definitely have a read through the linked articles as well.

    Bel, did I teach you nothing at the Bootcamp - if you pay less than £29.99 there's a risk you may be buying a fake (and then they might not work ;))

    Here's the official site as I know how much you enjoyed wearing mine... http://www.powerbalanceuk.com/

    Excuse my ignorance on the above product - I never knew something like it existed. Is it for real? Not wanting to sound negative but it looks like... dare I say it... a snake oil product. Have I missed something here... I'm curious & :confused: !

    Rather than snake oil I prefer to call it a placebo band ;)

    Briefly discussed here from post #17 onwards: http://www.podiatry-arena.com/podiatry-forum/showthread.php?t=29484

    And it is very much for real. Keep your eyes peeled next time you watch Sky Sports News - you'll be surprised how many of them you spot.

    Hey Craig,

    I think if we are serious about these for one moment we would all agree the 'science' behind them is flimsy as best, and absent at worst. But as we all know sportsmen and women are among the most superstitious group of individuals we tend to encounter. They tend to subscribe heavily to the lucky charm effect. And there is a little evidence to show this may work: http://www.dailymail.co.uk/news/worldnews/article-1270093/New-research-shows-lucky-charms-DO-work.html

    If we are honest the footballers probably wear them as fashion accessories. I wear mine as I play alot of golf. I don't think there is a single other sport where you need quite such a mental game to compliment the physical game you are playing. Whatever works for ya I say...

    I was only have a stir Ian...:D

    Question- Do you still get a placebo effect when you know it is a placebo?;)

    I agree the athletes are often superstitious, but in this case there is a portion of them that are paid a lot of cash to wear them too... I'd wear my underpants on the outside if you paid me that sort of coin.

    Thats ok buddy I'm used to it - I had Spooner and Bel giving me grief for a whole weekend about it :eek:

    I'm quite concious of the huge contradiction I am - trying to live my life by the evidence based mantra and then wearing a bit of blue plastic around my wrist because I think it'll help me take the money off my playing partners on a Wednesday morning! Your question is one I have pondered - why do I wear this band if i know it's effects are only placebo at best? And yet... I persist in doing so. I can only assume that like most I seek comfort in the feeling that I may on some level at least be in control of my own luck.

    I did e-mail Powerbalance about sponsoring me to wear mine, but they haven't replied yet. It seems a Podiatrist who plays off 17 may not have quite the same marketing prowress as Ian Poulter. Who knew...

    Running stride peak forces inversely determine running economy in elite runners.
    Støren Ø, Helgerud J, Hoff J.
    J Strength Cond Res. 2011 Jan;25(1):117-23.
  14. Were the sum of the vertical and horizontal forces normalised for body weight? They also found inverse correlation with height and body fat, if you are taller and fatter you are going to have higher impact forces.
