Computers: Electronics aids the athlete: Biomechanical systems are useful in human factors engineering, and in the design of sports equipment and prosthetic devices

Olympic athletes intent on breaking world records are turning to sophisticated software programs and high-speed computer systems to plot their performances and find ways to improve them. The software and computer systems analyze slow-motion movies of an athlete's movements and estimate bone and muscle stresses in relation to the movements. From this information, it is possible to postulate some optimum movements that might help an athlete break an existing record.
