中长跑是耐力性练习,从技术的结构来看它属于周期性运动。其项目特点是在较长时间内,中枢神经系统和肌肉活动要连续不断的接受刺激,人体要消耗大量的能量来维持比赛所需的高速度。由于速度的提高,其动作结构更趋向短跑的技术方面发展[1]。 Middle and long distance running is endurance exercise, from the technical point of view it belongs to the cyclical movement of the structure. The project is characterized by a long period of time, the central nervous system and muscle activity to be continuous stimulation, the human body to consume a lot of energy to maintain the high speed required for the game. Due to the increased speed, the movement structure tends to sprint technology development [1].
