The purpose of this investigation was to assess (a) proportions of children unable to perform each of three measures of upper body strength and endurance--pull-up, flexed-arm hang, and modified pull-up; (b) relationships among selected attribute variables of age, weight, percent body fat, and body mass index, and the three measures of upper body strength and endurance; and (c) the attribute variables which best predict scores for the three measures of upper body strength and endurance. Subjects were 104 elementary school children in Grades 1 through 6. Percentages of children obtaining zero scores were computed. Intercorrelations among the attribute and upper body strength and endurance variables were examined for significance and effect size. For each of the three measures of upper body strength and endurance, a max R2 forward stepwise, multiple regression analysis was performed to identify which attribute variables best predict the score of that particular measure. Analyses indicated that age and percent body fat were the best predictors of pull-up and flexed-arm hang scores, whereas age and body mass index best predicted the modified pull-up score.
(a)无法完成三项上肢力量和耐力测试（引体向上、屈臂悬垂和改良引体向上）中每一项的儿童比例；(b)年龄、体重、体脂百分比和体重指数等选定属性变量与三项上肢力量和耐力测试之间的关系；以及(c)最能预测三项上肢力量和耐力测试分数的属性变量。研究对象为104名1至6年级的小学生。计算了得零分儿童的百分比。检验了属性变量与上肢力量和耐力变量之间的相互关联的显著性和效应大小。对于三项上肢力量和耐力测试中的每一项，进行了最大R2向前逐步多元回归分析，以确定哪些属性变量最能预测该特定测试的分数。分析表明，年龄和体脂百分比是引体向上和屈臂悬垂分数的最佳预测指标，而年龄和体重指数最能预测改良引体向上分数。
