They are some of the most "energy efficient" creatures on Earth. Sled dogs run all day long and don't seem to get tired. Researchers want to understand what's so different about their physiology.
Researchers at Oklahoma State University have been studying the dogs' physiology for years. It has been established that sled dogs dramatically increase their insulin sensitivity during training for events such as the annual 1100 mile Iditarod race in Alaska. That insulin sensitivity permits them to use fat much more efficiently for energy.
"If we can figure out what exercise is doing to start the process, then we may be able to find how it can be applied to everyone, whether or not they are physically able to exercise."
Does it go, without saying, that PETA opposes the research?
