随着训练理念的发展,现代短跑越来越重视摆臂技术。国外运动员在20世纪80年代已经使用直腕摆臂技术,包括很多的女子运动员,国内运动员还在使用普通的半握拳摆臂技术,尤其是在青少年运动员中较为多见。我们基层教练员对短跑技术进行研究,也应开始重视对上肢摆动技术,包括手臂摆动时手指的伸展度。所以说我们应该对摆臂进行细致与完整的研究分析,使跑的技术结构更趋向于完善合理,更加符合运动生物力学原理,符合人体解剖的结构特点,从而使跑的技术更节省化和效率化。理论上认为:上肢的屈肌群力量一般都大于伸肌力 With the development of training concept, modern sprinters pay more and more attention to swing arm technology. Foreign athletes in the 1980s have used straight arm swing technique, including many women athletes, domestic athletes are still using ordinary half-fist swing arm technology, especially in young athletes more common. Our grassroots coaches to study the sprint technology, should also begin to pay attention to the upper limb swing technology, including the arm swinging finger extension. Therefore, we should conduct detailed and complete research on the swing arm so that the technical structure of running tends to be more perfect and more reasonable, more in line with the principles of sports biomechanics, and in line with the structural features of human anatomy, so that the running technology is more saved and more efficient The In theory, the flexor muscles of the upper extremities are generally greater than the extensor force
