Does Grunting Help Tennis Players Improve Their Game?

Grunting may help tennis players improve their game, according to a 2014 Hardin-Simmons University study. Players who grunted while hitting the tennis ball made shots travel 5 miles (8.1 km) per hour faster than if they made no noise at all. This is thought to be due to the exhaling that occurs during grunting, which gives muscles more power and stability. Researchers believe there may also be a mental component, as grunting may help players motivate themselves. Grunting may also negatively affect their opponents’ ability to hear the ball and judge its direction; therefore, critics have called to ban grunting in tennis.
