Performance analysis system KiSwim for swimming / 9691A

KiSwim, the performance analysis system for swimming, provides kinetic and kinematic information about starts, turns and relay changeovers immediately. Two multi-component force plates on top of the solid start block record the forces for each leg separately. An instrumented grab bar measures the force exerted by the hands and arms for different types of starts. The portable turning plate is easy to install and does not require any construction work on the pool wall. Its large size and very slim design allow for measurements of starts and turns without affecting the swimmer's movements. All components include piezoelectric sensors. Five high-speed video cameras capture the swimmer's movements over and under water at 100 fps. They allow for a precise measurement of position and split times over 15 m distance at high resolution. The data acquisition system provides a frame by frame synchronization of force plate and video data. The software displays the video along with a biomechanical analysis of the kinetic and kinematic information in a way easy to understand.
