Grunting DOES make you better at tennis
Tennis stars such as Maria Sharapova who grunt during matches could be giving themselves an advantage - and not just because it’s distracting.
Scientists found that players who let out a groan as they hit the ball sent it travelling significantly faster, reducing the amount of time their opponent had to set up a good return shot.
Over the course of the match the grunter was more likely to win, they said.
The team from the University of Nebraska found ball velocity increased by 3.8 per cent when players grunted compared to when they hit the ball silently.
They said that the forced expiration makes the upper body more stable, which in turn increases the transfer of power from the body to the arm.
And they said that players who trained for a long period of time using the technique could experience even better results.
