The International Cricket Council has confirmed details of the slow bowler research programme that will take place during the ICC Champions Trophy in September.
The second npower Test at Edgbaston marks the start of the detailed programme of slow bowler filming, which will continue throughout the ICC Champions Trophy, covering the slow bowlers of all participating teams.
The project is being undertaken by the ICC to gather detailed scientific data to help address the issue of suspect bowling actions among slow bowlers.
ICC General Manager – Cricket David Richardson, explained how the filming programme will be carried out: “Starting with Edgbaston, we are using high-speed cameras positioned behind the bowler’s arm and square of the wicket to film slow bowlers actions’ at 250 frames a second, which is five times faster than standard TV cameras.
“The footage from both cameras is then combined and converted by a software programme to create a three-dimensional image of the action, together with the ability to analyse it in every detail. This will provide us with a new generation of information that can be used in considering levels of tolerance for the accepted amount of extension at the elbow, either in terms of straightening or hyper-extension of the arm,” said Mr Richardson.
The ICC has commissioned Dr Paul Hurrion, a leading human movement specialist, to carry out the filming programme and provide interpretation of the data.
There has been less research carried out into slow bowling than faster bowlers, so this project will provide a clear scientific explanation of what actually happens during the delivery action of the world’s leading slow bowlers. Although a laboratory is likely to produce slightly more accurate data because of the controlled conditions, a competitive match situation guarantees the correct levels of player effort and technical application in the most realistic conditions.” Paul Hurrion
“Once Dr Hurrion’s data has been processed and analysed following the completion of the ICC Champions Trophy, it will be used by the ICC and its specialist advisors to consider if the current levels of tolerance for slow bowlers need to be reviewed based on this new information,” confirmed David Richardson.
The 15 matches of the ICC Champions Trophy in September provide a rare opportunity to film the actions of all slow bowlers in competing teams at the same time under similar match conditions. The project will be the most extensive ever carried out into the actions of international slow bowlers.
None of the data collected by Dr Hurrion will be used to assess the actions of any slow bowler that might be reported for a suspect action during the tournament. Any such reports will be dealt with under the standard ICC process, based on match footage supplied by the host TV broadcaster.

ECB’s Head Sports Physiologist and Biomechanicst, Nigel Stockill films Nasser Hussain during net practice prior to viewing on the Quintic Software.
“The majority of net sessions are filmed, giving the players the opportunity to view their technique frame by frame. Players have built up a library of good technique on their laptops, which is analysed via the Quintic software. Quintic is a biomechanical analysis software package that enables stride length, release hieght, speed to be calculated…”
