GPS World - With Racing Heart

A new GPS/video system that tracks skiers' position, their 100-kilometer-per-hour speed, and heart rate now gives the athletes, their coaches, and television viewers a novel performance analysis tool. The GPS data quantifies video motion analysis and enables evaluation of a skier's performance and technique from startgate to finish. A heart-rate monitoring device further correlates the racer's cardiovascular strain to the course profile and technical difficulties encountered.
