摘要

　　　目前我们的高考体育特长生对考前立定跳远的训练方法使用还比较单一，考前冲刺的提高效果并不理想，这一问题受到许多学生的关注与重视。随着体育运动的不断发展，在短期内采用沙地跳跃训练来提高立定跳远成绩这一方法应给以充分的关注。本论文将通过文献资料法、实验法及数理统计法针对短期沙地跳跃训练对立定跳远成绩的影响做实验研究，对两所中学的13名高考体育特长生进行短期训练，设置实验组与对照组。结果表明两种训练方法对立定跳远成绩的提高都有影响，但沙地训练比硬地训练的提高效果更显著。因为沙地阻力与硬地相比增大了许多,延长了蹬伸时间，经过沙地跳跃训练后再回到硬地起跳就会保持在沙地起跳中的动作结构，这样就容易在短期内提高运动员的立定跳远成绩。

ABSTRACT

　　　at present our country sports teacher of sports speciality students jumping ability training is relatively single.exam sprint enhancement effect is not ideal ,this problem is many students attention. Along with the sprots development, in the short term by sandy training to improve jumping ability of this methob should pay attention. This paperthrough the methods of literature ,experiment and mathematical statistics methob for short-term sand jumping on the jumping ability of experimental study, respectively on two secondary school 13college entrance examination of sports students for sports student for short-term training . setting the experimental geoup and the control group , the results from testing of view although the two training methods on spring force rise to have effect , but in training than hard training in the short term can improve jumping `ability .Because the sand resistance and hard to larger than many other training methods, with the relative ratio, sand jumping athletes after training, back hard take-off is maintained in the sandy take-off in the action structure, so it is easy to improve the springing ability.
