Perhaps one of the best known examples of biomechanics in action is the British world record triple jumper Jonathan Edwards. Edwards refined his technique by using biomechanical analysis during a spell at Florida State University in the United States.
Biomechanists do not work alone. They are part of a team that includes sports psychologists, nutritionists, physiotherapists and medical support, all working closely with the coaches to fine-tune the athletes' performances.
Payton has been working with the disabled swimming team since 2000. He visits each of the three high-performance swimming centres in the UK (Stirling, Swansea and Manchester) at least three times per year, analysing the swimmers' techniques and performance. He also attends a lot of competitions, both in the UK and abroad, producing race and competition analyses. It is an intense schedule. As soon as one competition is over, the focus is straight on to the next. Just weeks after the success in South Africa, the attention now is on the 2008 Olympics in Beijing.
Some of the biomechanical support he provides is immediate, based on video analysis and watching from the poolside. But there is a vast range of specific techniques and processes to draw on. Kinematic analysis, for example, uses high speed cameras and three-dimensional images to study a particular movement, producing a very detailed picture of what the athlete is doing, such as the range of motion, rate of movement, or rate of acceleration, both in and out of the water.
Kinematic analysis doesn't reveal anything about the forces involved in that movement, however. So a second technique is to measure the forces that are acting on and within the athlete's body, such as tethered force analysis, where the swimmer is tethered to a force transducer which measures the forces the swimmer produces, the stress levels they produce and how well they are sustained over a period of time.
