Abstract

Introduction

The six-minute walk test is a stress test that provides information about exercise tolerance in chronic diseases. The aim of the study was to develop reference equations with normal values for the test in healthy children aged 6 to 12 years in our paediatric reference population.

Patients and methods

The six-minute walk test was carried out in a sample of 236 healthy children, analyzing pre- and post-test variables, and we developed reference equations selecting variables that turned out to be significant (P < .05).

Results

The pre- and post-test values, respectively, were 97.82% (SD, 0.64) vs 97.82% (SD, 0.59) for oxygen saturation; 96.59 bpm (SD, 16.11) vs 131.89 bmp (SD, 22.64) for the heart rate; 0.52 (SD, 0.83) vs 3.01 (SD, 2.42) for the degree of dyspnea (Borg scale) and 0.68 (SD, 0.98) vs 2.95 (SD, 2.26) for the degree of lower extremities fatigue (Borg scale). The average distance walked was 668.03 meters (SD, 87.36) (671.42 m in boys [SD, 92.2] vs 664.22 m in girls [SD, 81.81]). We fitted predictive equations that included the variables age, height and difference between baseline and final heart rate. We also generated percentile charts of the distance walked for height.

Conclusions

Age, height, regular physical activity and obesity had an impact on test results. Obtaining reference values for the 6-minute walk test in healthy children is necessary for its application in clinical practice.

西班牙萨拉戈萨市健康学童六分钟步行测试的正态曲线。

导言六分钟步行测试是一种压力测试，可提供慢性疾病患者的运动耐量信息。这项研究的目的是在我们的儿科参考人群中，为 6 至 12 岁的健康儿童制定具有正常值的六分钟步行测试参考方程。患者和方法我们对 236 名健康儿童进行了六分钟步行测试，分析了测试前和测试后的变量，并选择具有显著性（P < .05）。结果测试前后的血氧饱和度值分别为 97.82%（SD，0.64）vs 97.82%（SD，0.59）；心率分别为 96.59 bpm（SD，16.11）vs 131.89 bmp（SD，22.心率为 96.59 bpm（SD，16.11） vs 131.89 bmp（SD，22.64）；呼吸困难程度（博格量表）为 0.52（SD，0.83） vs 3.01（SD，2.42）；下肢疲劳程度（博格量表）为 0.68（SD，0.98） vs 2.95（SD，2.26）。平均步行距离为 668.03 米（标度为 87.36）（男生为 671.42 米[标度为 92.2]，女生为 664.22 米[标度为 81.81]）。我们拟合了预测方程，其中包括年龄、身高和基线心率与最终心率之间的差异等变量。结论年龄、身高、经常运动和肥胖对测试结果有影响。要将 6 分钟步行测试应用于临床实践，就必须获得健康儿童 6 分钟步行测试的参考值。
