Nordic Walking Enhances Oxygen Uptake waithout Increasing the Rate of Perceived Exertion in Patients with Chronic Obstructive Pulmonary Disease
29 Mar 2025
In healthy subjects, Nordic walking (NW) generates higher oxygen uptake (V˙ O 2 ) than standard walking at an equal rate of perceived exertion (RPE). The feasibility and positive outcomes of NW in patients with chronic obstructive pulmonary disease (COPD) have been reported. The aim of the current study is to assess the physiological responses and RPE during NW in COPD patients.
In 15 COPD patients [mean (SD) age 67 (9) years] with a forced expiratory volume in the 1st s of 55% (15)], V˙ O 2 , minute ventilation and heart rate were measured with a portable system during the 6-min walking test (6MWT), incremental shuttle walking test (SWT), 6-min NW on solid ground (6mNW ground ) and 6-min NW on soft dry beach sand (6mNW sand ). The RPE using a modified Borg scale was assessed after each test.
