Muralitharan is awaiting the decision over his bowling action

Australian vice-captain Adam Gilchrist has questioned the biomechanical testing of Muttiah Muralitharan's bowling action.

Gilchrist said tests in a laboratory are flawed because they cannot be compared to cricket field conditions.

Muralitharan's new delivery which spins away from right-handers was reported by umpire Chris Broad.

Gilchrist said: "I have got to question why they bother doing a test like that whether it is Murali or anyone else."

The wicket-keeper believes the International Cricket Council should consider looking at their rules on chucking rather than review one of Murali's deliveries.

The Sri Lanka Cricket Board is set to receive the report in the next few days.

It would be very difficult for someone to actively change their motion in less than one-hundredth of a second Biomechanical expert Jacque Alderson

If fault is found with the spinner's action, he will have to undergo remedial work or drop the so-called doosra from his repertoire.

Biomechanical expert Jacque Alderson believed the test was a satisfactory way to test bowling actions.

She said: "I think it would be highly unlikely that someone will be able to change their action inside that environment but I would not say it would be impossible.

"But to be honest I don't know any other way it could be tested.

"You would have to say it would be very difficult for someone to actively change their motion in less than one-hundredth of a second."

Muralitharan took 28 wickets in the home series against Australia last month, while Australia leg spinner Shane Warne grabbed 26 to move to 517, just two short of West Indian Courtney Walsh's world record.

Muralitharan's action has been the source of controversy since he was no-balled for throwing by umpire Darrell Hair in a Test match at Melbourne in December 1995.
