The Claim
In physically active adults performing the Wingate Anaerobic Test, verbal encouragement containing swearing is associated with a 4.2% reduction in average power output in males and no significant change in females.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When physically active men perform a high-intensity cycling test, hearing swear words during encouragement reduces their power output by 4.2% compared to neutral encouragement; women's performance does not change under the same conditions.
See the scientific wording
In physically active adults performing the Wingate Anaerobic Test, verbal encouragement that includes swearing is associated with a 4.2% reduction in average power output among males, while females show no significant change, suggesting that the social context of language use may differentially affect high-intensity exercise performance based on sex.
When men hear swearing during intense exercise, their brain interprets it as social judgment, which activates stress pathways that suppress the signals from the brain to the muscles, making them produce less power. Women do not show this response.
What the research says
1 studyStudy: The Effect of Verbal Encouragement with Swearing on High Intensity Exercise Performance
When men heard someone swear while cheering them on during a super-hard bike test, they actually performed worse—by about 4%—but women’s performance didn’t change. This might be because the swearing made the men feel self-conscious, especially if the person cheering was a woman.
