Don't tell anyone, but sometimes, when I'm at the gym, I sneak a glance at the treadmill next to mine to see how many miles that other person is running. I love it when the StairMaster tells me I've climbed as high as the Taj Mahal. But nothing feels better than when the machine orders me to punch in my initials because I've burned more calories than anyone else that week (except for a person called LHM).
What makes us so attuned to physical competition — even against rivals we never meet? What makes us get emotionally invested in games we aren't a part of? Why do we fret about the fates of athletes we don't know?
Evidence suggests that our brains may be hard-wired for physical competitions because they tell us something about our place in the social pecking order.
A recent study suggests that winners of athletic contests feel more than pride at winning. They feel dominant over those they bested. Researchers at San Francisco State University used high-speed photography to examine the immediate reactions of competitors in Olympic medal matches in judo. In the milliseconds after victors realized they had won, they pumped their fists and puffed out their chests, postures associated with dominance. Losers tended to slouch and cover their faces — gestures related to submission and shame.
"People from all around the world did essentially the same configurations," said David Matsumoto, a psychology professor who co-authored the study with Hyisung Hwang. "When you find people from many different cultures doing the same things, you start to think there is something fundamentally human about it."
Stranger still, they found that victors from cultures where social status matters most — such as Eastern Europe or East Asia — made bigger displays of dominance than those from egalitarian societies. It shows that, on some level, winning in sports is about establishing oneself at the top of a social hierarchy. Victory gestures are an unconscious way to let everyone else know you're the boss.
The role of sport may even go beyond humanity. Male chimpanzees charge one another, shake their fists, and yell during contests over who holds the highest rank. These displays of physical prowess rarely involve actual violence. The show of superior power — that one chimp could kill a rival if he wanted to — is enough.
If sports are a nonviolent way to determine the social pecking order, then it explains why nations invest so much in the Olympic Games.
