Olympics-Some athletes really do whistle while they work

LONDON, Aug 9 (Reuters) - Trampolinists whistle, tennis

players grunt and Chinese women's superheavyweight weightlifting

champion Zhou Lulu screams "Fung shong!"

Those are just a few of the noises athletes competing for

medals at the London 2012 Olympics make in an effort to run,

jump, lift, hit and shine at the top of the sporting world.

A packed crowd in London's ExCel arena roared as Zhou

approached the platform to set a new world record on Sunday,

screaming back at her as she shrieked in preparation.

Later, a demure and bespectacled Zhou smiled as she told

reporters that far from a war cry, she was actually saying

"Relax".

"So I can lift the weight, relaxing," she said.

At the trampoline, many of the athletes emit a short sharp

whistle while sailing high in the air to execute the twists and

somersaults which score them points with the judges.

Mental Performance Consultant Andy Barton told Reuters that

some noises may be involuntary, but others such as the whistling

may help athletes to stay in the performance zone, be part of a

mental routine or are a trigger for movement.

"Noises are fantastic triggers," Barton said, adding that

making noises may help some athletes remind their bodies of the

next move to be executed.

"Some people are quite auditory and they feed off external

sounds."

Barton said that athletes who have highly developed auditory

senses can use external noise for their advantage.

"I was working with a showjumper the other day and she talks

to herself, talking herself around the course."

He said Olympic silver medallist tennis player Maria

Sharapova's grunting may be part of a routine, which may be why

the Russian shot down questions about whether she might stop

after complaints about her noises on the tennis circuit this

year.

"Certainly not now as I have been doing it since I was four

years old," Sharapova told reporters during Wimbledon in June.

"It's definitely tough and impossible to do when you've played

this sport for over 20 years."

Fencers shout and scream, stomp and argue, whipping off

their masks to prance after a successful point, intensely aware

that this is psychological warfare as much as it is physical.

It is common for both fencers to turn on the referee,

shouting exuberantly in the hope of swaying a point their way

even though there is now slow-motion replay to separate the

great actors from the true winners.

In hockey, some of the Asian women's teams - China and South

Korea - pretty much jabber throughout the whole game.

While most teams talk, shout and communicate with each other

to direct players around the pitch, these sides literally just

go on with no end, some have suggested to disrupt their

opponents so they can not hear each other's directions.

Barton said that there are bad external sounds which can put

auditory athletes off their game, but one sound helping host

nation Britain at the London Games has been the cheers of the

home crowd, pointing to the deafening roar for six-time gold

medal cycling champion Chris Hoy in his last race on Tuesday.

"That noise just drove him around that last bend."
