ICC aiming to assess bowling actions during games

ESPNcricinfo staff

The ICC is working on developing technology that will allow the legality of bowlers' actions to be assessed during matches and training sessions. According to an ICC release, it has entered the second phase of an agreement with a consortium of Australian cricket, sports science and sports engineering institutions in order to produce the technology.

The process will include devices known as 'inertial sensors', which employ technology similar to that used in iPads, mobile phones and car crash impact detection systems. The technology is being developed with a view to keep it cost effective, and making the device wearable on the bowler's arm during matches and training, without it hindering performance.

Dave Richardson, the ICC's chief executive, said the technology would be a big step forward for the game. "The ICC is keen to see this technology implemented in elite cricket and believe it will be a significant stride forward in detecting illegal bowling actions in match conditions. We would also like to see the technology used in training environments as a tool to help bowlers correct their flawed bowling action.

"We are encouraged by the progress made so far by the Australian research team and also acknowledge the MCC, who have made a significant financial contribution to the project."

For now, bowlers whose actions are considered suspect are required to attend ICC-approved biomechanics laboratory tests to assess the amount of elbow extension (flex) in their bowling action. In November 2004, the ICC set a uniform 15-degree limit on elbow extension for actions to be considered legal.

The project is being managed on behalf of the ICC by Praxis Sport Science, an Australia-based sports science consultancy company headed by Dr Marc Portus, who was involved with the original research behind the 15-degree tolerance threshold.

This phase of the three-step project is concerned with the technology's measurement methods and precision against current laboratory protocols, and will conclude in late 2013. In 2014, phase three will begin and focus on making the technology more comfortable for players.

    Love the idea. Ajmal, Bhajji and every doosra bowler should be worried.

    This is tricky. First of all the ICC must give fairness to all cricketers not just a few. The fairest way is when a batsman is out let him be out or when he is not out let him be not out. The only way this can happen is get the DRS active for all.What about the very obvious legal bowlers who don't get their wickets cuz there is no DRS.So the point is get the DRS in first then get rid of the chuckers. What is the point of getting rid of the chuckers & still the legal guys don't get their wickets or for that matter some get wickets they don't deserve. Some people are against the DRS but even the weak DRS as they call it is better than some umpires.

    A good initiative from the ICC and a concern for some Doosra bowlers. Money well spent by the MCC.

    Waste of time, waste of money. First remove D/L method and start using VJD. then remove David Kendix, who is creating this stupid ICC rankings.

    The problem with labratory testing is that all the blokes who are chucking the ball will make every effort to bowl with a perfectly straight arm during the testing. Which makes it a flawed process. This is a very good idea.

    For all of you saying there's bigger issues in cricket - I think that keeping the legitimacy and fairness in the game is a pretty important issue to be assessing.

    Why are so many people against this?

    Finally people will be tested actually during a match and not simply in a meaningless out of competition lab test where they don't use the same action as in game.

    Only people who should be worried are chuckers or people who know their team has chuckers who have been getting away with it.

    @Dr_Van_Nostrand - You mean all the impractical ideas are backed by Aus, Eng, and NZ.

    did they get approval necessayr from various members ?...why does ICC make a fool of themselves by announcing first and then realizing that they are too toothless to implement without approval of member sides

  • dummy4fb on August 28, 2012, 11:10 GMT

    BCCI should oppose this...like DRS!!!
