Validation of "CENTR(AR)" walking trails: Different field criteria do not lead to different physical activity intensities in people with COPD.

Background: Validating walking trails is essential to promote physical activity (PA) safely and confidently in people with COPD.

Objectives: We aimed to validate predetermined light, moderate, and vigorous intensities of walking trails in people with COPD.

Methods: This cross-sectional study included individuals with COPD walking in predetermined light, moderate and vigorous intensity trails.
