To date no studies exist investigating the effects of Nordic Walking in patients with COPD. Therefore the aim was to determine the feasibility of Nordic Walking in COPD patients at different disease stages. Furthermore we aimed to determine the short- and long-term effects of Nordic Walking on COPD patients daily physical activity pattern as well as on patients exercise capacity. Methods Sixty COPD patients were randomised to either Nordic Walking or to a control group. Patients of the Nordic Walking group n 30 age 62 9 years FEV1 48 19 predicted underwent a three-month outdoor Nordic Walking exercise program consisting of one hour walking at 75 of their initial maximum heart rate three times per week whereas controls had no exercise intervention. Primary endpoint daily physical activities measured by a validated tri-axial accelerometer secondary endpoint functional exercise capacity measured by the six-minute walking distance 6MWD . Assessment time points in both groups baseline after three six and nine months. Results After three month training period in the Nordic Walking group time spent walking and standing as well as intensity of walking increased A walking time min day A standing time 129 26 min day A movement intensity m s2 while time spent sitting decreased A sitting time -128 15 min day compared to baseline all p as well as compared to controls all p . Furthermore 6MWD significantly increased compared to baseline A 6MWD 79 28 meters as well as compared to .
