Research Reveals Swearing Can Enhance Physical Performance

Swearing may serve as an unexpected tool for enhancing physical performance, according to new research published by the American Psychological Association. A study conducted at Keele University in the UK indicates that individuals who use expletives during physical challenges can push their limits further and endure longer than those who refrain from swearing.

The research suggests that the act of swearing reduces inhibitions, boosts confidence, and helps individuals enter a focused “flow” state. Lead researcher Richard Stephens explains, “In many situations, people hold themselves back—consciously or unconsciously—from using their full strength. Swearing is an easily available way to help yourself feel focused, confident, and less distracted, and ‘go for it’ a little more.”

Understanding the Psychological Mechanism

Previous studies have linked swearing to improved performance in physically demanding tasks. These include challenges such as maintaining a hand in ice water for extended periods and performing body weight exercises like chair push-ups. The research team aimed to identify how swearing affects physical performance and understand the psychological mechanisms at play.

The hypothesis posited that swearing shifts individuals into a more disinhibited mental state. In this state, social norms and internal hesitations may hold less sway, allowing for greater effort.

Experimentation and Results

To test this theory, researchers conducted two experiments involving a total of 192 participants. In both experiments, participants performed chair push-ups while either repeating a chosen swear word or a neutral word every two seconds. After completing the task, they answered questions regarding their emotional state during the exercise.

The surveys evaluated various mental factors associated with disinhibition, including levels of positive emotion, amusement, distractions, and confidence. Additionally, the researchers measured psychological “flow,” described as a state of deep focus and immersion in an activity.

The findings confirmed previous research, revealing that participants who swore during the chair push-up task could maintain their body weight significantly longer than those who used a neutral word. When the data from the two experiments were combined with results from earlier studies, it became evident that the performance advantage correlated with heightened levels of psychological flow, reduced distractions, and increased self-confidence—key elements of a disinhibited state.

Stephens noted, “Swearing is literally a calorie neutral, drug-free, low-cost, readily available tool at our disposal for when we need a boost in performance.”

The research team plans to further explore whether the benefits of swearing extend beyond physical challenges, potentially influencing other aspects of performance in various contexts. The study is published in the journal American Psychologist under the title, “Don’t hold back: Swearing improves strength through state disinhibition.”
