一、在跑步中的应用 (一)在短跑教学中,为了防止起跑时急抬头、仰体、迈大步,影响速度的发挥,可在起跑线前适当位置(5米左右)拉一条离地1.5米高的橡皮筋,限制学生的身体姿势。 (二)终点冲刺跑,要求学生应以最快的速度冲过终点。有些同学撞线时出现跨大步或跳起来的错误动作,这时可在终点线处拉一条1.6～1.8米高的橡皮筋,以此来提醒和防止到达终点时跨大步或跳起来撞线。 (三)跨栏跑是技术较为复杂的项目,教学时,可利用橡皮筋代替栏板,学生会信心百倍,大胆“攻栏”,顺利做出“压栏”“提拉”等动作,就是跨不过去也不会跌倒。改进过栏技术时,有些学生概念不清或者身体素质跟不上技术要求,容易出现跳栏现象,这时可在栏架垂直上方1～1.2米处拉一条橡皮筋,要求学生在橡 First, the application of running (a) in the sprint teaching, in order to prevent the starting rush anxious rise, Yang body, step by step, affect the speed of play, in the starting line in the right place (5 meters) to pull a 1.5 Meter high rubber band to limit the student’s body posture. (B) the final sprint run, requiring students to the fastest speed crossed the finish line. Some students hit the line when there is a big stride or jump up the wrong move, then at the finish line to pull a 1.6 to 1.8 meters high rubber band, in order to remind and prevent the end of the step across or jumped up line. (C) Hurdle race is a more complex technology projects, teaching, the use of rubber bands instead of railing, the students will be confident hundred times, bold “offensive bar,” smooth “pressure bar”, “pull” and other actions, Never fall in the past. Improve the bar technology, some students unclear concept or physical fitness can not keep up with technical requirements, prone to hurdles phenomenon, then in the vertical shelf above 1 to 1.2 meters pull a rubber band, requiring students in the rubber
