The aim of our research was to study the relationships between performance variables in a support backward swing (SBS), which was used as a progressive step in the learning procedure for a 1 1/4 straddle-piked front somersault and the swing prior to a 1 1/4 straddle-piked front somersault from support to bent arm support on the parallel bars (5/4S). Mitja Petkovsek, parallel bars gold medallist at the 2000 EC in Bremen, performed these elements. Kinematic analysis involved CMAS software (Praha, 1993), and the Suskana body segment model that has 17 points and 15 segments. Kinetic variables were estimated using 2D IMGIM software, which has 8 points and 6 segments (Colja and Cuk, 1994). The results indicated that some kinematic aspects of the two types of swings were similar but there were important differences in kinetic aspects of the motion. During the swing for the 5/4S, force and torque were higher than in the SBS.
我们研究的目的是探讨在1又1/4分腿屈体前空翻学习过程中的一个渐进步骤——支撑后摆（SBS）的运动学变量与从支撑到双杠屈臂支撑的1又1/4分腿屈体前空翻（5/4S）之前的摆动之间的关系。2000年在不来梅举行的欧洲锦标赛双杠金牌得主米佳·佩特科夫塞克完成了这些动作。运动学分析使用了CMAS软件（布拉格，1993年）以及具有17个点和15个节段的苏斯卡纳人体节段模型。动力学变量使用具有8个点和6个节段的二维IMGIM软件进行估算（科尔亚和库克，1994年）。结果表明，两种摆动的一些运动学方面是相似的，但在运动的动力学方面存在重要差异。在5/4S的摆动过程中，力和扭矩高于支撑后摆。
