    Physics of Running

    maya commented on evan's blog entry in Evan Plattens blog

    "When the body uses the calories it has consumed, it is not very efficient at conserving this energy. As the leg muscles contract to propel the runner forward, about 75% of the chemical energy that the runner has consumed is lost due to the heat (thermal energy) that the body gives off as it converts it stores (potential) chemical energy into kinetic energy." Could you please tell me where you have sourced, or if this is a primary source, this statistic from. Thank you.
