It is not yet completely known whether the 6MWT can be used to prescribe high-intensity exercise for patients with COPD.
To evaluate the ability of the six-minute walk test (6MWT) to prescribe high-intensity exercise for patients with chronic obstructive pulmonary disease (COPD).
Lung function, maximal inspiratory strength, symptoms and exercise capacity were evaluated in patients with COPD (n = 27) before and after a 12-week high-intensity exercise program. Criteria for high-intensity training were: 1) ≥75% of the 6MWT average speed; 2) American Thoracic Society/European Respiratory Society (ATS/ERS) criteria (≥60% of the maximal incremental shuttle walk test speed).
The 6MWT showed good positive and negative predictive values (0.69 and 0.71, respectively), and accuracy (0.70), good reliability (ICC 0.70 [95%CI 0.45-0.85]) and moderate agreement (k 0.41 [95%CI 0.13-0.67]) with the ATS/ERS criteria.
The 6MWT has good predictive ability and accuracy in relation to high-intensity exercise for patients with COPD.
6分钟步行试验（6MWT）是否可用于为慢性阻塞性肺疾病（COPD）患者开具高强度运动处方尚不完全清楚。
评估6分钟步行试验（6MWT）为慢性阻塞性肺疾病（COPD）患者开具高强度运动处方的能力。
对27例COPD患者在进行为期12周的高强度运动计划前后评估其肺功能、最大吸气力量、症状和运动能力。高强度训练标准为：1）≥6MWT平均速度的75%；2）美国胸科学会/欧洲呼吸学会（ATS/ERS）标准（≥最大递增往返步行试验速度的60%）。
6MWT显示出良好的阳性和阴性预测值（分别为0.69和0.71）以及准确性（0.70），与ATS/ERS标准具有良好的可靠性（ICC 0.70 [95%CI 0.45 - 0.85]）和中度一致性（k 0.41 [95%CI 0.13 - 0.67]）。
6MWT对于COPD患者的高强度运动具有良好的预测能力和准确性。
