摘要
借助运动生物力学的研究手段和方法,采用三维摄像获得3名优秀散打运动员鞭腿动作技术图片,应用美国APAS图象解析系统分析鞭腿技术的动作特征。为散打技击教学、科学训练及技击实战提供理论依据。在完成鞭腿动作技术时,鞭腿膝关节应尽量处于屈曲状态,以达到减小转动惯量,加快转动角速度。运动员身体躯干应主动积极地扭转,加大主动肌群的弹性势能,增大肌肉工作的距离。应主动加强大关节用力,充分发挥大关节的潜力。应强调各近侧端环节的制动,使人体的动量矩以较合理的途径传递予远侧端环节,有效地提高动作速度,增大打击效果。
In this paper, the authors have obtained the technical photos of three top strikers under biomechanie research methods by means of 3 - D photography, then they have analyzed these photos according to APAS photo analysis system for the purpose of providing theoretical basis for striking teaching, scientific training and competition. At the time of finishing whip-leg movements, the knee joint of the motion leg should be bent so as to decrease the moment of inertia, increase the twist angular velocity. The strikers should emphasize the sudden stop of the near side joints and make the moment of momentum be passed to the far side joints in a proper way so as to improve the action speed and striking effect.
