Insults that empower: science finds that swearing boosts physical performance

According to a study published in American Psychologist, using swear words during exercise can increase endurance, strength, and self-confidence.

The research involved 192 volunteers, who were asked to perform strength exercises such as chair-assisted push-ups. Part of the group had to repeat a taboo word every few seconds, while the control group used neutral terms. The results were clear: those who swore managed to sustain their effort for longer and with greater intensity.

The scientists explain that the effect is not due to a physiological spike, such as an increase in adrenaline, but to a psychological process known as disinhibition. By breaking a social norm, the brain reduces certain internal restraints, making it easier to focus and commit to the task. In practical terms, attention shifts from pain or fatigue to the action itself.

Other previous studies had already pointed in the same direction. Similar trials showed improvements of between 9% and 22% in strength and endurance tests, as well as greater pain tolerance when taboo language is used.

The authors do note, however, that the effect depends on cultural context and personal relationship with this type of language. Also, constant use could reduce its impact over time. Even so, the study opens the door to a simple, cost-free tool to get a little more out of every workout.
