摘　　要：采用运动学研究法对冯喆、王冠寅完成的双杠"挂臂团身后空翻两周成挂臂"动作进行了研究。由手倒立开始下摆,两臂主动屈臂挂杠,下摆时足尖远伸,并逐步形成"背弓"。下摆时,冯喆先屈臂后下摆,王冠寅边屈臂边下摆。王冠寅屈臂下浪节奏较均匀,挂臂后增大并保持"背弓",下摆至杠下垂面时,王冠寅的"背弓"较冯喆明显,获得的重心合速度较大,挂臂前摆过垂面后迅速向上兜腿,同时两臂用力压推杠。该动作腾空较低,翻转速度较快。当重心过杠水平面时两手用力推离杠,离杠后迅速屈髋、屈膝、抱腿,团身要紧。空翻挂臂时,要积极撒腿、伸髋,主动展体、抬头挺胸去挂杠。王冠寅的空翻高度、翻转及挂臂展体要优于冯喆。This article analyzes the movements of ＂Roll Backward with Double Salto Backward Tuck to Upper Arm Hang＂ on the parallel bars which are completed by Wang guan - yin and Feng Zhe through the method of kinematics analysis and oth- ers. The resuhs show that the athletes start to swing from bandstand, hang with arms bent actively; toes extend while swing- ing, and gradually form a ＂ack arch＂ Wang Guan - yin bends arms and swing at the same time while Feng Zhe bends arms before swing. Wang Guan - yin＇ rhythm of swing is more homogeneous. He opens body to the best after hanging arm to in- crease and maintain ＂ack arch＂ He presents a better ＂ack arch＂ ban Feng Zhe under the bars, and gets a higher resultant ve- locity. He upraises legs quickly after swinging over a vertical plane, and presses the bars at the same time. The movements need to shoot low, roll fast, push with efforts and left the bars rapidly when the center of gravity is above the bars, pike, bend knees and hold legs quickly after hands leaving the bars, tuck tightly. Stretching out legs and hips to arm hang, open the body to hang with head high. Wang Guan - yin performs saho fully and better than Feng Zhe.
