Have you ever heard a tennis player grunting while they hit a ball? It's usually the sound of power and energy being released as they smash the ball. But why do tennis players grunt?

The History of Grunting in Tennis

Grunting has been around in tennis since the late 1980s, when Monica Seles, a professional tennis player, became well-known for her signature tennis grunt with every stroke.

It’s believed that tennis players grunt because it helps them to focus on their shot and add more power to their swing.

Does It Help to Grunt?

So have you ever been to watch a tennis match and heard players grunting like they're in pain? Or maybe you've grunted yourself while trying to hit that forehand.

Whether or not it helps, grunting is a common occurrence on the tennis court. But why do players grunt? In a bit, we'll take a look at the science behind this age-old question.

The Science Behind Grunting

Tennis players grunt for several reasons, but one of the most frequently cited ones is that it helps them generate more power.

When a player grunts, their abdominal muscles engage more strongly, which increases their core stability and provides extra torque for their shots. This can help them hits the ball harder without sacrificing accuracy.

Additionally, some believe that grunting can help relax muscles during intense matches, which can lead to better performance overall.

Grunting has become a part of competitive tennis for many players today. Whether you believe it or not, the science behind it supports it as an aid in helping generate speed and power during matches.

Ultimately, it's up to each individual player if they want to grunt or not; but either way, grunting clearly has its place on the court!

The Numbers

But why does this work? Research suggests that when players grunt, it helps them engage their core muscles for more stability and power. Studies have even shown that grunting can increase performance by as much as 4%. This is especially true during a serve, where grunting can help generate up to 7% more force than without grunting. Additionally, some believe that grunting helps keep players from tensing up before hitting a ball. All of these benefits help in an improved performance.
