Abstract

A method is presented for determining the contributions made by contact and aerial twisting techniques in filmed performances of twisting somersaults. An 11-segment simulation model is used to determine the effects of removing asymmetries about the sagittal plane. Tilt contributions are determined for four competitive movements performed by an elite trampolinist. It is found that even in movements in which the twist is evident at take-off, aerial techniques make a greater contribution than contact techniques.

摘要

本文提出了一种方法，用于确定在拍摄的翻腾动作表演中，接触扭转技术和空中扭转技术所起的作用。使用一个由11个部分组成的模拟模型来确定消除矢状面不对称性的影响。对一名优秀蹦床运动员进行的四项竞技动作确定了倾斜贡献。结果发现，即使在起跳时扭转明显的动作中，空中技术的贡献也比接触技术更大。
