对肖俊峰完成双杠向后大回球转体180°动作进行了全面系统的分析，发现早伸展、晚下沉、落底沉实是该动作下摆阶段的关键技术所在。上摆阶段向后领臂保持较小的肩角与随后快速有力的振肩动作，两者在时空上的合理配合是该阶段的技术关键，同时也是完成该动作的主要技术特色。 A complete and systematic analysis of Xiao Junfeng’s completion of the parallel bar 180 ° swinging motion of the parallel bars showed that early stretching, late-sinking and bottoming-out were the key techniques of the pendulum stage. The pendulum arm keeps a smaller shoulder angle and then a fast and powerful shoulder movement. The rational cooperation between the two in the space-time is the key technology of this stage and also the main technical feature of this action.
