Any of you who study the science of exercise know that experts recommend you do different types of exercise or work out only every-other day to prevent muscle damage. So, how do sled dogs compete in the 1,100 mile Iditarod Trail Sled Dog Race from Anchorage to Nome, Alaska, which spreads over nine days?
Michael Davis of Oklahoma State University‘s Center for Veterinary Health Sciences has studied the sled dogs for the past 10 years, before, during, and after races both in the lab and in the field. His findings may even have implications for humans.
