运动员在长期的训练过程中，当移动速度提高到一定程度时，其运动水平就会出现停滞、难以提高的现象，产生了速度障碍。产生速度障碍的客观原因是：从运动技能形成的规律上讲，技能动力定型的形式，使得运动员已掌握技术动作的空间特征固定下来，在时间特征上稳定下来。从能量 Athletes in the long-term training process, when the moving speed increased to a certain extent, the level of their movement will be stagnant, difficult to improve the phenomenon, resulting in speed obstacles. The objective reason for producing speed obstacle is that from the law of sports skill formation, the form of skill dynamic fixing makes the spatial characteristics that the athlete has mastered the technical action are fixed and stable in time characteristic.
