现代跳远理论研究表明,在所有影响跳远成绩的因素中,助跑速度的作用巳大于70％。所以,不论在各个层次的跳远技术训练中,教练员、运动员都很重视助跑速度的提高。有资料表明,优秀跳远运动员速度利用率应在93％左右。 助跑的任务是在发挥最大可控速度的前提下,准确地完成起跳;助跑速度应是呈逐渐上升趋势,在起跳前达到最高。 而在训练过程中,由于起跳板的客观存在,青少年运动员在初级训练中,往往就形成了在助跑后4～6步(距起跳板前10米左右)降低助跑速度上板起跳的条件反射。 为了有效解决这一问题,我们在跳远技术训练中,取消起跳板,扩大起跳范围,使运动员心理上达到“无板”意识;在减少一个注意因素的情况下,使运动员注意力尽可能放在全力助跑上,并能按一定节奏,自然进入起跳阶段。
Research in modern long jump theory shows that the effect of run-up speed is greater than 70% of all factors that affect long jump performance. Therefore, no matter at all levels of long jump technical training, coaches, athletes attach great importance to improve the running speed. Data show that the excellent long-jump athletes speed utilization should be about 93%. The task of running is to accurately perform the take-off under the premise of maximizing the controllable speed. The running speed should be gradually increasing and reach the maximum before take-off. In the process of training, because of the objective existence of the bouncing board, the juvenile athletes often form the conditioned reflections on the board during the initial training, which reduce the running speed 4 to 6 steps after the running (about 10 meters before the bouncing board). In order to effectively solve this problem, we eliminated the starting plate in the long-distance technical training and expanded the range of take-off so as to make the athletes mentally achieve the “no-plate” mentality. By reducing the attention factor, the athlete’s attention should be minimized Fully run, and according to a certain pace, naturally into the stage of take-off.
