“腾空外摆腿720°接马步”是武术竞赛中自选项目里C级难度动作,若能成功完成,将获得0.4的最高分值。许多高水平运动员选择了这一难度动作,但要成功完成,并非易事。腾空外摆腿720°接马步动作中的“起跳”是技术关键。运用“运动录像解析法”对2012年山西省青少年武术比赛中获得男子南拳前四名运动员的腾空外摆腿720°接马步中的“起跳技术”动作进行解析,探讨“腾空外摆腿720°接马步”起跳技术动作的运动学特征。结果表明:运动员起跳离地瞬间垂直速度小,下肢蹬伸爆发力不足,肩髋关节扭转幅度不充分,是造成该项难度动作完不成的主要因素。
“Vacate the swing leg 720 degrees then take the horse ” is a C-level optional movement in the martial arts contest, if successful, will get the highest score of 0.4. Many high-level athletes choose this difficult action, but to be successful, it is not easy. Vacate the outer leg 720 ° then take the step action “jump” is the key technology. Use “motion video analysis method” in 2012 in Shanxi Province Youth Wushu competition to obtain the top four male athletes of the South boxing vacated swing legs 720 ° then horse in the “take-off technique” action analysis to explore Kick-off leg 720 ° take the horse "take-off technical movement kinematics characteristics. The results show that: the athletes take off from the ground at an instant when the vertical speed is small, the lower limbs extend underexposure force, shoulder hip torsion is not sufficient, is the main reason for the difficulty in completing the action.
