Mind Over Matter

We’ve all heard the old adage about running being 90% mental. Turns out it might be true, and scientifically proven to boot. Tim Noakes, M.D., author of Lore of Running, has long argued that it is the brain that allows or limits endurance performance rather than the body. His “central governor” theory postulates that “the brain is there to look after you and to make sure whatever you do, you do it safely,” as he puts it.

Noakes says that the brain holds us back from pushing past a certain point. “There’s a control mechanism to make sure that you reach the finish line not in a completely, utterly wilted state,” he claims. “You always have a little reserve.” Or as some would interpret this, you can always push a little harder.

While past running research was preoccupied with the physiological side of endurance performance, a small group of researchers recently set their sights on examining the role of the brain. Not only does this research emphasize the idea of mind over matter, it also demonstrates that the brain can be trained to allow the body to physically handle more. After considering the research, we went in search of examples of competitive runners who have figured out ways to overcome the limits our brains put on our bodies. They offer sound advice on methods to coach your mind, not just your muscles.

Confusing Mental Fatigue and Physical Fatigue

Consider the following scenario. You’ve had a long, hard day. Your kids are nagging you, your boss is riding you, and there’s a sink full of dirty dishes and a mile-high pile of bills waiting for you at home. Managing to get in a run, much less a track workout or tempo session, seems like a monumental task.

Researchers at Bangor University in the UK set out to examine why it is that mental fatigue can lead to the perception of physical fatigue during exercise. Dr. Samuele M. Marcora and colleagues compared two groups. While both groups were to complete a high-intensity cycling exercise, one group was given a challenging, but sedentary, 90-minute computer test beforehand. The other watched “emotionally neutral documentaries” for 90 minutes.
