每年带领学生参加体育高考,总会发现许多考生的摆臂动作不够正确,诸如左右摆、上下摆、耸肩摆、幅度小等,有的甚至十分僵硬。正确的摆臂动作是良好技术的标志,它不仅能维持身体平衡,而且能加强下肢动作效果、加大后蹬力量、提高跑速。摆臂的力量、速度、方向和幅度对步长、步频及跑的直线性等都有直接影响,因此,在体育高考的训练中,应结合力量、速度训练加强摆臂技术的训练,在细节上下功夫,使考生掌握正确的摆臂技术。
Every year to lead students to participate in sports entrance exam, always find that many candidates are not right arm swing, such as left and right pendulum, pendulum, shrugging, amplitude and so on, and some even very stiff. The right arm movement is a sign of good technology, it can not only maintain the body balance, but also to strengthen the action effects of the lower limbs, increase the strength of the rear pedal, improve running speed. The strength, speed, direction and amplitude of the swing arm have a direct impact on the step length, the pitch frequency and the straightness of the run. Therefore, training of the swing arm should be strengthened in combination with strength and speed training in the training of the college entrance examination. The details work hard so that candidates have the right arm technology.
