The Claim
During resistance exercise in resistance-trained young men, the psychological effects of swearing (increased motivation and arousal) are greater in magnitude than its mechanical effects on explosive velocity, indicating that psychological mechanisms are the primary drivers of its ergogenic potential.
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.
In young men trained in resistance exercise, swearing during workouts increases motivation and arousal more than it improves explosive power, meaning the mental effects are stronger than the physical ones.
See the scientific wording
The psychological effects of swearing during resistance exercise—increased motivation and arousal—are more pronounced than its mechanical effects on explosive velocity in resistance-trained young men, suggesting psychological mechanisms may dominate its ergogenic potential.
When someone swears during a hard lift, their brain reacts as if they are facing a threat, which turns on the body's stress system. This releases adrenaline and noradrenaline, making muscles fire harder and faster, while also making the person feel more fired up and determined. The mental boost is stronger than the physical speed gain, so the main reason swearing helps is because it makes the person feel more motivated, not just because their muscles get stronger.
What the research says
1 studyStudy: Swearing Enhances Explosive Performance and Psychological Responses during Resistance Exercise
Swearing before lifting made people feel more pumped up and motivated, and also helped them lift faster—but the feeling of being fired up was even stronger than the speed increase, meaning the mental boost might be the main reason it helps.
