Running activates hundreds of genes throughout the body, with a mother lodehappening in your butt. Here, they dictate the intricate workings of thelargest muscle in the human body, the gluteus maximus. The butt itselfprovides the ballast needed for stability, so we can accelerate while balancing our forelimbs and trunk on our hindquarters.
Daniel Lieberman of Harvard University studied the activity of this muscle in volunteers during a walk and a jog. "When they walk, their glutes barelyfire up, but when they run, it goes like billy-o," he said.
Our big butt muscles are part of the evolution that separates us from our less cheeky primate cousins who never had to chase game for long distancesin order to survive. We evolved to run. It's a theory that holds true today,and explains why so many of us are able to cover the distances of a marathon and beyond.
Engage your natural ability and invite non-runners to fire up their glutes on Friday, September 18th, during the Road Runners Club of America's 4thAnnual National Run@Work Day. The RRCA will provide brochures and posters,and will post your Run@Work Day event for FREE on the RRCA Calendar at http://www.rrca.org/
