向前大回环振浪技术是发展高低杠动作的先导基本技术,也是衡量运动员高低杠技术水平的主要标志。用固定高速摄影(100格/s)、影片数字化和计算机数据处理等方法,对世界冠军樊迪等5名运动员的向前大回环振浪技术进行运动学和动力学分析。结果表明:1)樊迪的技术与众不同,符合运动生物力学原理和体操技术特点,代表了高低杠难度技术发展的新趋势,可供广泛借鉴和运用。2)在振浪技术中,过杠和沉肩两个环节是关键;不同的重心位置和身体姿势以及过杠、沉肩时间的早晚都会对其它环节产生截然不同的影响。3)身体摆越低杠时,头部和肩、髋关节角度的变化,可反映出过杠技术的优劣,并直接影响整个振浪技术。
Big wave forward wave technology is the development of uneven bars lead the basic technology, but also a measure of the level of the main technical level of the athlete mark. With fixed high-speed photography (100 cells / s), digital video and computer data processing methods, the world champion Fan Di and other five athletes forward big loop vibration technology kinematics and dynamics analysis. The results show that: 1) Fan Di’s technique is unique and consistent with the principles of sports biomechanics and gymnastic techniques, representing a new trend in technological development of uneven bars, which can be widely used for reference. 2) In the wave technology, the two parts of the cross-bar and the shoulder sinking are the key points; different center of gravity position and body posture and the cross-bar and shoulders time will produce completely different effects on other links. 3) Body under the bar, the head and shoulder, hip angle changes, can reflect the pros and cons of over-the-bar technology, and directly affect the entire wave technology.
