Abstract

The author has developed the same three-dimension digital shot dynamometry system as international standard shots of sportsmen and sportswomen. Its core is force sensor of inside resistance strain type. This system can carry on wireless measurement alone, and also carry on the synchronous measurement of kinematics and dynamics with the camera, three-dimensional dynamometry platform. It can examine the force, force curve, resultant force value, curve and impulse of human bodies to shot in the three directions of X, Yand Z. This system is high in precision and reacts quickly. This system realizes unimpeded and hurtles chec'k. It is safe and reliable. It can continuously measure, record, display, store, information processing and output and print, etc. Training experiments prove that this system is not only a kind of scientific research instrument but also a kind of training monitoring system. It will offer the strong assurance to coach and athletes' scientific training.
