Description
1 study reviewed
In plain English

In physically active adults, using swear words during verbal encouragement does not change power output, self-confidence, or psychological flow during a high-intensity cycling test.

See the scientific wording

Verbal encouragement containing swearing does not significantly improve average power output, self-confidence, or psychological flow during the Wingate Anaerobic Test in physically active adults overall, contradicting prior claims that swearing enhances anaerobic performance.

Why this might work

When someone swears during a short, intense workout, their brain does not send stronger signals to their muscles, their heart rate and energy use do not increase, and their focus or sense of being 'in the zone' does not change. Their body responds the same way as if they heard neutral words.

  1. Study: The Effect of Verbal Encouragement with Swearing on High Intensity Exercise Performance

    When people were told to swear during a tough bike test, it didn’t make them stronger, more confident, or more 'in the zone'—except for men who seemed to get distracted when a woman told them to swear. Overall, swearing didn’t help.
