The BOA's elite performance director Sir Clive Woodward has placed his faith in the vision coach that helped England and South Africa to World Cup glory.

Dr Sherylle Calder has been taken on as a Visual Performance Skills Consultant on a four-year contract until 2012.

Woodward started working with the South African while England rugby coach, when she walked into his office and enquired why he was not weight training his players' eyes.

She went on to become a "one percenter" - a Woodward reference to his mantra of doing 100 things one percent better - in England's 2003 World Cup victory, and went on to repeat the trick with her native country last autumn.

Calder will be based at the Bisham Abbey National Sports Centre, while every British Olympian will be offered an eye test and free online training.

Woodward emphasised he was not attempting to impose his coaching techniques on individual sports; rather offering services that coaches could decide whether to take advantage of.

"I have been working with the coaches, understanding what we can do today and looking also at development," he told Eurosport.

"Now with the amount of investment coming in from UK Sport we've got nine boxers going to Beijing so there is a lot of good stuff already out there. We are just trying to add the one percent.

"There's no duplication because it is up to the coach. If you talk to the coach he will know whether anything is being duplicated and whether a particular thing is applicable to his sport.

"That's why representatives from each sport can come and see what is available and they can decide whether or not to use Sherylle.

"Although in fact we anticipate that she will not have many free spots in her diary."

Calder has little time to make an impact before the Beijing Olympics in August, although she said South Africa wing Bryan Habana's vision and perception increased markedly within six weeks.

"We don't want to be spreading ourselves too thin," Woodward added. "Obviously there is only limited time until Beijing and Sherylle will focus on certain athletes for whom she can make a difference."

However, Woodward claimed that British success in Olympic sports such as cycling and rowing was due in part to their willingness to embrace advanced coaching techniques.

"When you get inside the sports and look at the once where we are successful, like cycling, they have a proven record, they have worked on it a long time and they have the best people working in the sport," he said.

"You look at it and you just go 'wow, that's fantastic'. And they are the ones where they are pushing the boundaries of sports science."
