The OptoJump is an optical measurement system consisting of a transmitting and receiving bar combined with cameras. The system detects any interruptions in communication between the bars and calculates their duration. This makes it possible to measure flight and contact times during the performance of a series of jumps with an accuracy of 1/1000 of a second. Starting from these fundamental basic data, the dedicated software makes it possible to obtain a series of parameters connected to the athlete’s performance with the maximum accuracy and in real time. The absence of moving mechanical parts ensures accuracy and great reliability. Here at SportsPlus we use the OptoJump system in a variety of aplications including gait analysis and determination of return to play status after a concussion or surgery.
