ABSTRACT

This study examined the test–retest reliability of the standing long jump (SLJ) and the countermovement jump (CMJ) following consistent and non-consistent attentional focus cuing instructions in physically active young adults (n = 30). The systematic error (as standardize change in mean), random error (as typical error), the Bland and Altman method (limits of agreement, LOA), intraclass correlation coefficient (ICC), and two-way ANOVA with repeated measures were used to evaluate the reliability of measurements. Jump distance in the SLJ and jump height in the CMJ demonstrated acceptable reliability within the consistent and non-consistent attentional conditions. However, the consistent attentional condition resulted in smaller systematic errors, lower random errors, stronger ICCs, and narrower LOAs in comparison to the non-consistent condition. The present findings indicate that providing a consistent focus of attention instructions produced more reliable jump distance and jump height compared to providing a non-consistent focus of attention instructions to physically active adults.

摘要

这项研究检查了在身体活跃的年轻人（n = 30）中遵循一致和不一致的注意焦点提示指令后站立跳远（SLJ）和反向运动跳跃（CMJ）的测试-再测试可靠性。系统误差（作为标准化均值变化）、随机误差（作为典型误差）、Bland 和 Altman 方法（一致限，LOA）、类内相关系数（ICC）和重复测量的双向方差分析用于评估测量的可靠性。SLJ 的跳跃距离和 CMJ 的跳跃高度在一致和不一致的注意力条件下表现出可接受的可靠性。然而，与不一致的条件相比，一致的注意力条件导致更小的系统误差、更低的随机误差、更强的 ICC 和更窄的 LOA。
