通过利用爱捷运动分析系统对武术前扫腿900°与前扫腿540°进行对比研究发现,前扫腿900°与前扫腿540°右腿扫转速度相差不大,前扫腿900°完成情况主要受平衡因素影响。力图在前扫腿900°平衡技术上有所突破,在原技术基础上提出了利用左腿以膝关节为力点的快速左前旋技术来提高平衡能力,通过验证、分析发现此技术非常适合提高前扫腿900°平衡能力。 Through the use of Aijie motion analysis system to compare the pre-martial art scan of 900 ° and the front sweep of 540 ° found that the front swept 900 ° and the front swept 540 ° right leg rotation speed is not much difference, the front swept 900 ° Completion is mainly due to the balance of factors. In order to improve the balance ability of frontal swept 900 ° balance technique, based on the original technique, a rapid left-handed pre-rotation technique using the left leg and knee joint as a force point is proposed to improve the balance ability. The verification and analysis show that this technique is very suitable for improving the pre- Leg 900 ° balance ability.
