The current study sought to examine the construct validity of the Resistance Training Skills Battery for Children (RTSBc), a movement screen purported to assess resistance training skill in children. Children aged 7-10 years (n = 27, 21 males, 6 females) undertook measures of resistance training skill via the RTSBc, motor competence and muscular fitness. Using a median split for RTSBc scores, children were categorised as high or low resistance training competence. Univariate ANCOVAs, controlling for maturation, were used to examine whether measures of muscular fitness and motor competence scores differed as a function of RTSBc competence. Children who were classified as high for resistance training competence had significantly better motor competence (P = .001) and significantly faster 10 m sprint speed (P = .001). However, medicine ball throw and standing long jump scores as well as peak and average isokinetic muscle strength did not differ as a function of RTSBc (P > 0.05). In all cases maturation was significant as a covariate. This study is the first to demonstrate construct validity of the RTSBc as a measure of general motor competence and sprint speed, but not strength, in children aged 7-10 years.
本研究旨在检验儿童抗阻训练技能测试（RTSBc）的结构效度，该测试旨在评估儿童的抗阻训练技能。7-10 岁儿童（n=27，男 21 名，女 6 名）通过 RTSBc、运动能力和肌肉力量来评估抗阻训练技能。使用 RTSBc 评分的中位数分割，将儿童分为高或低抗阻训练能力组。采用单变量协方差分析（ANCOVA），控制成熟度，以检验肌肉力量和运动能力评分是否因 RTSBc 能力而存在差异。被归类为高抗阻训练能力的儿童在运动能力（P=0.001）和 10 米冲刺速度（P=0.001）方面明显更好。然而，药球投掷和立定跳远成绩以及峰值和平均等速肌力并没有因 RTSBc 而存在差异（P>0.05）。在所有情况下，成熟度都是一个重要的协变量。本研究首次证明 RTSBc 作为一种测量 7-10 岁儿童一般运动能力和冲刺速度的工具具有结构效度，但不能测量力量。
