ESTIMATION OF TAKEOFF-ANGLE IN THE LONG JUMP BY USING WiMAS
Keywords: WiMAS, accelerometer, takeoff-angle, the long jump
AbstractThere have been many studies on the biomechanics of the long jump, and the typical method has been video analysis. These studies provided a lot of new angles about movement of jumping (Jaitner et ai, 2001). However, video analysis has a flaw in that it takes a long time for the analysis. We produced a motion analysis system by using telemeter and micro sensor IC. We named this system WiMAS. WiMAS stands for Wireless Motion Analysis System. WiMAS has two merits. One of them ,is that it doesn't restrain the subject's motion, and the other is real-time feedback. In previous studies, we had measured the height of vertical jumps, and have recently developed a method for estimating a takeoff-angle in the standing long jump by using WiMAS. The purpose of this study was to develop a method for estimating the takeoff-angle in the long jump.
