To evaluate learning and encouragement effects on the 6-minute walk test in children between 6 and 12 years of age.
Two 6-minute walk tests separated by a 10-minute resting period were performed by healthy children between 6 and 12 years of age to evaluate the learning (part 1) and encouragement effects (part 2; randomization with and without encouragement). Distance and cardiorespiratory variables were used as outcomes.
148 children were recruited. The intraclass correlation coefficient estimates were 0.927 (95% CI, 0.893-0.951; part 1) and 0.844 (95% CI, 0.744-0.907; part 2). The test-retest agreement was verified for distance (P = .679) with a bias of 1.1 m (95% CI, -4 to 6), but the increase in distance with encouragement was significantly and clinically relevant (P < .001; +41 m; 95% CI, 33-50).
No training is required for the 6-minute walk test in children, in contrast with adults, but there was an encouragement effect on the walked distance in these children. Guidelines should take these results into account.

评估 6 分钟步行测试在 6 至 12 岁儿童中的学习和激励效果。
健康的 6 至 12 岁儿童进行两次 6 分钟步行测试，中间间隔 10 分钟休息时间，以评估学习（第 1 部分）和激励效果（第 2 部分；随机分组，有或无激励）。距离和心肺变量作为结果。
共招募了 148 名儿童。组内相关系数估计值为 0.927（95%置信区间，0.893-0.951；第 1 部分）和 0.844（95%置信区间，0.744-0.907；第 2 部分）。距离的测试-重测一致性得到验证（P = .679），偏差为 1.1 米（95%置信区间，-4 至 6），但激励对距离的增加具有显著的临床相关性（P < .001；增加 41 米；95%置信区间，33-50）。
与成人不同，儿童进行 6 分钟步行测试无需训练，但这些儿童的行走距离存在激励效应。指南应考虑这些结果。
