The 3D motion analysis, which has been launched by Specialist Service, provides a scientifically accurate assessment of running styles by measuring joint angles at the hip, knee and ankle. It is hoped the technology will benefit athletes hoping to compete at the 2012 Games, as the analysis helps to prevent the chances of injury.

The service, supported by the Nuffield Orthopaedic Centre and the University of Oxford's Department of Engineering Science, is believed to be the first of its kind in the UK.

Devon athlete Pavey, who admitted the technology helped her to discover more about her running technique, said: "To have cameras picking up infrared imagery and an athlete’s movement is amazing, it is very accurate. I am hoping it can benefit me and other athletes ahead of next year’s Olympic and Paralympic Games. It is a massive opportunity in a sportsperson’s career so I hope I can be there."

The system, which is also aimed at non athletes, uses reflective markers to create a 3D computer model of an athlete’s running style. Twelve cameras record the positions of each marker position 200 times a second, meaning that 12,000 images are produced by the markers each minute.

Dr Jessica Leitch, who specialises in running injury biomechanics, explains: "Understanding the way your bones and joints move is critical for avoiding and treating injury, and for maintaining an efficient running style. This 3D motion analysis provides comprehensive information and picks up subtle things like excessive rotation of the hip which can then be addressed to prevent future injury."
