  • Re: Oscar Pistorius has "a considerable advantage"?

    Thanks Jim,

    I was intrigued that they quote Bruggemann as saying:

    "The prosthetics return 90 per cent of the impact energy, compared to the 60
    per cent of the human foot."
    I wonder what people think about that statement - are there any studies to
    back up the 60% figure for normal running? It seems very high to me.


    PS: I do wish news reports would call artificial limbs 'prostheses' instead
    of 'prosthetics' :-)
