The athletes’ cry: between cathartic expression and recurring controversies

A powerful serve and a liberating scream. In tennis, in particular, it’s not uncommon to hear impressive shouts on the court, contrasting with the calm some athletes display during interviews.

Tension at its peak, nerves giving way, movement unleashed: while the scream complements a physical stance, it also helps clear the mind. Indeed, science confirms that the scream of athletes (tennis players, karatekas, etc.) has many benefits.

Physically, screaming leads to better abdominal contraction and thus increases the athlete’s power. A study from the United States and published in 2014 shows that screaming can increase the speed of a tennis ball by 6km/h. Beyond this technical advantage, the psychological benefits are just as significant. This very specific form of expression helps athletes not only release pressure but also boost their confidence during the effort, while maintaining a high level of concentration.

For example, the battle cry in karate, the "kiai," represents a key step in the practice that requires total commitment—both physical and psychological—to unleash one’s full energy.

The shout can also serve as a strategy, a powerful tool for intimidation, or a way to wear down the opponent. In tennis, this particular form of communication is often criticized, with some viewing it as cheating. Furthermore, the International Tennis Federation is currently working on regulations regarding these shouts.
