The Static Balance Stability´s Biomechanics Research on Youth Trampolinists

Using the German Zebris measuring systems for plantar force distribution to measure the youth trampolinists´ static balance stability who attended the National Youth Trampoline Championship, Guilin, Guangxi from the 18th--23th of November 2009. We got 6 balance parameters results which are ellipse´s width, height, area, track length, horizontal offset and vertical offset. Using these 6 parameters for comparing the differences of balance stability when youth trampolinists eyes open stand on both feet with closed and eyes open stand on single foot with closed. Through this way to discuss the features of trampolinists´ static balance performance and provide a theoretical basis for trampolinists´ scientific athlete selection and training.
