大学生体质测试单项成绩插值计算研究

Interpolation Method Calculation of the Single Event Result of College Students’Physical Fitness Test

大学生体质测试成绩是其能否顺利毕业的必要条件之一。在《国家学生体质健康标准》中,各测试项目得分是“分档”给出的,并未给出各“分档”的中间得分,且常规算法只取其中各分档对应得分。研究利用“线性插值”方法,计算出各“分档”的中间得分,并与传统方法进行对比,结果发现:利用“插值”计算得出的得分比常规方法得分略微提高,且对60分以下成绩更显著。插值法总体符合体测要求,并对提高学生参加体育锻炼的积极性具有一定的促进作用。

College students’physical fitness test score is one of the necessary conditions for university graduate.In the National Standards For Students’Physical Health,the test score is given by the“step”,without the middle of the score.What’s more,the conventional algorithm methods only take“standard”in the corresponding step of scoring.In the paper,the author uses the method of using the linear interpolation method,which can calculate each“step”in the middle of the score.Through comparing with the traditional method,the results show that using“interpolation method”can increase score slightly compared with the conventional method of score,and more significant to 60 points below.Generally,interpolation method conform to the requirements,and it can enhance students’enthusiasm when take part in physical exercise.
