摘　　要：研究目的:研究双蹬技术下速度轮滑蹬、收腿技术的变化与应用。研究方法:主要利用文献资料法、比较研究法和观察法进行研究。研究结论:1、双蹬技术的应用,实现了运动员第二次蹬地加速,提高了动力性做功,解决了此滑行阶段出现的降速问题。2、双蹬技术对传统的蹬、收腿技术的影响主要体现在浮腿落地后外韧蹬地动作的出现,双腿蹬地角度都相对一定程度的缩小,上体重心摆动幅度加大,对身体重心和浮腿着地过程的控制提出了新的要求。建议:在长距离项目中,双蹬技术对蹬、收腿的技术的改进效果更加突出,可以帮助运动员取得更好的成绩。Objective:To study the change of leg pulling after application of double pedaling techniques in speed roller skating.Methods:Literature review,comparative study and observation were used.Research conclusion:1.The application of double pedaling technology can realize the second pedal acceleration,improve the power performance,and solve the problem of speed reduction in this sliding stage.2.The influence of double pedaling technology on traditional pedaling and retraction technology is mainly reflected in the appearance of the flexible pedaling movement of the floating leg after landing,the angle of both legs pedaling the ground is reduced to a certain extent,and the swing amplitude of the upper body's center of gravity is increased,which puts forward new requirements on the control of the body's center of gravity and the process of the floating leg landing.Suggestion:In the long distance event,the effect of improving the technique of pedaling and retraction based on the technique of double pedaling is more outstanding,which helps the athletes to achieve better results.
