步行速度是一个重要的功能指标，在不同长度的课程中测量，但目前还不清楚课程长度是否影响测量的步伐。共有136名老年人完成了两个连续的试验，每个3米和6米步行课程，其顺序是随机分配的。我们计算一致性相关系数（CCC），并创建Bland-Altman图来评估两个课程距离之间的关系。平均步行速度较快的6米课程和每个课程的第二次试验。有高度一致性之间的第一次和第二次审判的3米和6米课程。3米和6米课程具有良好的重测信度和更快的步行速度比早期试验晚。后期试验的课程之间更高的一致性表明，当结合不同课程长度之间的步行速度测量时，练习试验和调整课程长度的实用性。
Walking speed is an important marker of functionality that is measured over courses of varying lengths, but it is unclear if course length affects measured pace. A total of 136 older adults completed two consecutive trials each of 3-m and 6-m walking courses, the order of which was randomly assigned. We calculated concordance correlation coefficients (CCC) and created Bland–Altman plots to evaluate the relationship between the two course distances. Average walking speed was faster for the 6-m course and the second trial of each course. There was high concordance between the first and second trials for both the 3-m and 6-m courses. The 3- and 6-m courses had excellent test–retest reliability and faster walking speed in later than earlier trials. Higher concordance between courses for later trials suggests the utility of practice trials and adjusting for course length when combining walking speed measurements between different course lengths.
