直腿后滚翻是高中一年级教材中的一个内容,从技术动作完成上分析,主要有三点,一是降低重心位置,便于手撑地和滚动;二是减少转动半径,加快滚动角速度;三是用力推撑,提高重心位置,便于抬头,反转成屈体站立。为了突破这三点,用一些膝关节 Straight leg roll after the turn is a textbook in high school in a content analysis from the completion of technical action, there are three main points, one is to reduce the center of gravity to facilitate hand holding and rolling; the second is to reduce the radius of rotation, speed up the rolling angular velocity; three Forced support, improve the center of gravity position, easy to rise, reversed into a pike stand. In order to break through these three points, use some knees
