The Claim
Vocalizing a self-selected swear word immediately before bench pressing at 75% one-repetition maximum increases self-reported motivation by 43% (from 45.5 to 65.0 arbitrary units, d=1.05) and psychological arousal by 52% (from 42.3 to 64.5 arbitrary units, d=1.32) in resistance-trained young men.
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 resistance-trained young men, saying a swear word right before lifting a heavy weight increases self-reported motivation and psychological arousal compared to not saying a swear word.

Vocalizing a self-selected swear word immediately before bench pressing at 75% one-repetition maximum increases self-reported motivation by 43% (45.5 to 65.0 arbitrary units, d=1.05) and psychological arousal by 52% (42.3 to 64.5 arbitrary units, d=1.32) in resistance-trained young men, indicating a psychological 'psyching-up' effect.
Saying a strong swear word activates brain areas that process emotion, which turns on the body's stress response. This releases adrenaline and noradrenaline, making the person feel more alert and driven, and preparing the muscles to produce more force quickly.
