At 101 decibels, Wimbledon's defending champion Maria Sharapova is judged the loudest grunter so far. Is it only female players who make a racket on court - and is it tactical?

It was Monica Seles who originally inspired the "gruntometer", the measuring of decibels on Centre Court by newspapers. The first of the female power players, the Yugoslav teenager's trademark was a loud grunt each time she belted the ball across the net.
Seles registered 93.2 decibels, enough to make her quarter-final opponent at Wimbledon in 1992 demand that she not be allowed to make noise. Seles clammed up - and eventually lost the tournament to Steffi Graf.
Seles would have been a formative influence when today's grunters - Maria Sharapova, Anna Kournikova, the Williams sisters among them - were first honing their skills.
Today grunting among female tennis stars is the norm rather than the exception.
And grunting begets grunting, as quieter players try to out-psyche their opponent, says retiring Wimbledon referee Alan Mills. "A kind of counter-grunt has emerged in recent years whereby offended parties ape their opponent's noises."
At Wimbledon on Tuesday, defending champion Sharapova shattered her own personal record with a grunt of 101.2db - almost as loud as a police siren heard at close-quarters. She, like Seles and other grunters before her, denies that it is a tactical move to put off opponents. It is, they say, simply a natural release of pent-up energy as the ball is hit.
What a racket!
But Mr Mills has told reporters that not only are these grunts deliberate, tennis coaches are teaching women players to grunt the loudest.
Many of those noted for their grunts are the product of Nick Bollettieri's Florida tennis academy, where Seles first yelped her way through training aged 12. Bollettieri said last week that he doesn't encourage his students to make noise: "Never once has that entered int
