The Claim

Swearing during explosive resistance exercise improves barbell velocity but does not increase repetitions to failure in resistance-trained young men, and this effect is transient and limited to single-effort movements.

Cause and effect
1 study reviewed
In plain English

In resistance-trained young men, swearing during explosive lifts increases barbell speed but does not allow more repetitions to failure, and the effect lasts only briefly.

See the scientific wording

The performance-enhancing effect of swearing during explosive resistance exercise is likely transient and limited to single-effort movements, as it improves barbell velocity but not repetitions to failure in resistance-trained young men.

Why this might work

Saying a swear word triggers a strong emotional response that turns on the body's stress system, causing adrenaline and noradrenaline to flood the bloodstream. These chemicals make muscles and nerves work harder and faster, allowing a person to push with more power in a single burst, but they don't help the muscles keep going for longer.

  1. Study: Swearing Enhances Explosive Performance and Psychological Responses during Resistance Exercise

    Swearing helps you push a heavy weight faster in one quick lift, but it doesn’t let you do more lifts before getting tired. The study proved this exact thing.
