在奔跑和跨栏过程中,当人的重心移过支撑腿后,向前的动力来源除了惯性、后蹬产生的角分力之外,主要是支撑腿向后扒地产生的水平推动。可见,股后肌群是产生跑动加速的动力主肌群,但又是很易拉伤的部位。 在训练中安排一些股后肌群的专门动力性练习,不仅可提高其力量,预防其损伤,而且其动力轨迹上有利于形成步频损失小的“屈腿蹬”跑步技术(有利于折叠小腿,向前摆进)。以下简便易行的练习可一试。 In the process of running and hurdling, when a person’s center of gravity moves beyond the support leg, the motive force of the forward force is mainly horizontal support of the support leg backward instead of the angular force generated by the inertia and the rear pedal. Visible, posterior muscle group is to produce the main motivation to accelerate the running muscles, but it is also very easy to strain the site. In the training arrangements for some posterior posterior muscle group specialized dynamic exercise, not only can enhance their strength, to prevent their injury, and its trajectory is conducive to the formation of a small step loss of the “bent leg pedal” running technique (in favor of folding legs , Move forward). The following easy to practice can be a try.
