立定跳远,在前些年的体育高考中被许多省市定为考试项目,在近几年的初中升学考试体育加试中又被大部分的省市设为考试项目。在立定跳远考试的距离丈量中,传统的丈量工具一般是软皮尺。 笔者在长期的实践中发现用软皮尺丈量立定跳远的距离,测量误差较大,且丈量者在丈量过程中易于作弊,主要表现在以下几个方面:1.丈量者不把软皮尺拉直;2.丈量者把软皮尺拉斜,不与起跳板(线)垂直且不拉直;3.丈量者在软皮尺的起点扣留一定长度再进行丈量;4.丈量者把软皮尺一弹大约报上个数据。 针对上述具体情况,笔者在长期的探索和实践中
Standing long jump, in the sports college entrance examination in previous years by many provinces and cities as the test project, in recent years, junior high school entrance examination sports add in most of the provinces and cities as test items. In the distance measurement of the standing long jump test, the traditional measurement tool is usually a soft tape measure. In the long-term practice, the author found that using a soft tape measure to determine the distance of the long jump, the measurement error is relatively large, and the measuring person is easy to cheat in the measurement process, mainly in the following areas: 1. Measurements do not straighten the soft tape measure; 2. The measurer pulls the soft tape measure obliquely, not perpendicular to the starting board (line) and does not straighten; 3. The measurer detains a certain length at the starting point of the soft tape measure and then measures; 4. The measurer puts a soft tape measure on the bullet The previous data. In view of the above specific circumstances, the author in the long-term exploration and practice
