摔跤常见技术动作开始的发力特征研究

Study of the Features of Force Breaking at the Moment Starting a Skill in Wrestling

采用专门研制的摔跤测力装置,对过胸摔、挟颈背、拉臂转移和滚桥技术动作开始发力的力学特征进行测试分析,结果表明,上述动作开始的发力具有力值大和力的梯度大的特点,均有爆发用力的特征。其中过胸摔和滚桥主要把位发力最大,其总合力和力的梯度也最大。

Mechanical features of force breaking at the moment starting skills like full twist throw, cross-buttocks, arm drag switch and momentary bridge were tested and analyzed using specially developed wrestling dynamometer. The results showed that force breaking when starting the above skills were featured by big value and large gradient of force as well as explosiveness. Force breaking at the moment starting full twist throw and momentary bridge in main holding position were the strongest and their total joint forces and gradient of force were also the strongest.
