A recent study suggests the power of profanity may play a role in exercise success.

A team of psychologists from the University of Keele in the U.K. have hit upon the importance of swearing for improving muscle strength and workout stamina. It seems that muttering or yelling (there is no difference in effect) a well-timed profanity has the ability to reduce exercise pain.

It’s hypothesized that swearing activates the sympathetic nervous system, boosting adrenaline production. The latest study had people undergoing a cycling test where they were given instructions to repeatedly vocalize a neutral word or a profanity. Those who swore (repeatedly) were able pedal harder for longer.

But before you start adding curses to your curls, it’s worth noting that it’s not necessarily the words themselves, but rather the emotional intensity of the angry utterances. As one of the researchers said, “We have yet to understand fully the power of swearing.”

Whatever the case, choose your moment and think of those around you!
