Body by Iditarod

Researchers are studying the uncanny metabolism of Iditarod sled dogs, whose endurance among other creatures on Earth is almost unparalleled. In learning how the dogs can alter their own metabolism to “switch off” fatigue, the scientists hope to find a similar way for humans to better their endurance as well.
Me, if I had to eat semi-frozen Alpo for days on end, I’d find a way to switch off my metabolism, real quick too.

Many mushers have reported that their dogs lose a lot of weight racing in the Iditarod. The dogs aren’t “fatigue-proof” and are often worn out by racing. Their copper enzymes get depleted, which leads to anemia and fatigue. For the facts, visit the Sled Dog Action Coalition website, http://www.helpsleddogs.org.

That New York Times article was one of the most interesting I’ve read in a long time. I’d heard about this ability of sled dogs before (I’m very involved in the mushing world) but it was great to see it published in a major paper.
Having done a lot of mushing myself, I found out pretty quick that humans tire out a LONG time before sled dogs! It’s amazing how quickly they can bounce back after a run!
