To determine the need for a practice walk for the endurance shuttle walk test (ESWT) following the performance of two incremental shuttle walk tests (ISWTs) - one practice and one test - on the same day.
Retrospective data analysis of shuttle walk test measurements. All participants had performed two ISWTs and two ESWTs at a single visit, prior to commencing pulmonary rehabilitation.
Outpatient physiotherapy department of a university hospital.
Forty-four patients (33 males, 11 females) with a primary diagnosis of chronic obstructive pulmonary disease, referred for routine pulmonary rehabilitation.
Shuttle walk test distance and time, Borg breathlessness score, heart rate and pulsed oxygen saturation.
The mean age of the group was 67.6 years [standard deviation (SD) 9.0] and mean forced expiratory volume in 1 second was 37% predicted (SD 13). The mean times walked during ESWTs 1 and 2 were 195 and 207 seconds (SD 115 and 138), respectively. Using the analysis recommended by Bland and Altman, the mean of the individual differences (d) between Tests 1 and 2 was 12 seconds, with limits of agreement from -88 to +112 seconds.
A practice endurance shuttle walk is unnecessary following performance of ISWTs on the same day.
在同一天进行两次递增往返步行试验（ISWT）——一次练习和一次测试后，确定耐力往返步行试验（ESWT）是否需要进行预演步行。
对往返步行试验测量数据进行回顾性分析。所有参与者在开始肺康复之前，于单次就诊时进行了两次ISWT和两次ESWT。
一家大学医院的门诊理疗科。
44例患者（33例男性，11例女性），初步诊断为慢性阻塞性肺疾病，被转诊接受常规肺康复治疗。
往返步行试验的距离和时间、Borg呼吸困难评分、心率和脉搏血氧饱和度。
该组患者的平均年龄为67.6岁[标准差（SD）9.0]，1秒用力呼气量平均为预测值的37%（SD 13）。ESWT 1和ESWT 2期间的平均步行时间分别为195秒和207秒（SD 115和138）。使用Bland和Altman推荐的分析方法，测试1和测试2之间个体差异（d）的平均值为12秒，一致性界限为-88至+112秒。
同一天进行ISWT后，无需进行耐力往返步行预演。
