【摘要】 目的：在体育实践中，一些上肢力量测验常被采纳，如引体向上、屈臂悬垂、双杠屈臂，但相应的评分标准间的等价关系式还没被确定起来。本实验利用等值技术对三个上肢力量类测验项目作实证性研究，确定三者之间的等值关系式，并比较不同等值方法对它们进行等值的准确性和稳健性。 方法：453名大学男生分别进行了三项测验，每项测验间隔一周，测验项目顺序为均衡设计。等值方法包括线性等值、一般的等百分位等值和平滑的等百分位等值。测试数据随机分成两部分：等值样本、交互验证样本。三测验的等值关系式通过等值样本来确定，而各种等值方法的等值精确性和稳健性则由交互验证样本通过RMSD指标来评估。 结果：1)在进行平滑等百分位等值时，平滑模型的选取应视不同的测验项目而定。2)在对三种上肢力量类测验等值的方法中，线性等值方法的效果最好。3)根据本实验得出的三测验间的等值转换表，对照《国家体育锻炼标准》，发现其中的测验评分标准在部分成绩段等值性较好，部分成绩段等值性不太满意。更多还原

【Abstract】 Objective: A number of upper body strength tests are being frequently employed in testing practice. The equivalence of the standards, however, has not been confirmed. Therefore, the purpose of this study was to determine the equivalence of three upper body strength tests, including pull-up, push-up and flexed-arm hang.Methods: Three tests are administered to 453 male collegians. Each test was administered in a week apart, and the testing order was counterbalanced. The equating methods included the unsmoothed and smoothing equipercentile equating and linear equating. The collected data were randomly split into two samples: equating sample, cross-validation sample. The equivalent relationships of the tests were determined by equating sample, Using the cross-validation sample, the equating accuracy was evaluated by the index of Root Mean Squared Difference (RMSD).Results: 1) In smoothing equipercentile equating, smoothing model should be chosen according to different tests. 2) Among the equating method of three upper body strength tests, the linear equating functioned the best. 3) Based on the equivalent relationship derived from this study, the equivalence of the stands was evaluated. It was found that, while the equivalence of some of the standards was well established, the equivalence of others was not satisfactory.更多还原
