Interventions that included ET and PA counseling during PR were effective strategies to improve PA in COPD
BACKGROUND Physical inactivity is associated with poor outcomes in COPD , and as a result , interventions to improve physical activity ( PA ) are a current research focus .
However , many trials have been small and inconclusive .
OBJECTIVE The aim of this systematic review and meta- analysis was to study the effects of r and omized controlled trials ( RCTs ) targeting PA in COPD .
Nordic Walking improves daily physical activities in COPD: a randomised controlled trial
Background In patients with COPD progressive dyspnoea leads to a sedentary lifestyle . 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 aim ed 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 r and omised 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 vali date d 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 st and ing as well as intensity of walking increased ( Δ walking time : + 14.9 ± 1.9 min/day ; Δ st and ing time : + 129 ± 26 min/day ; Δ movement intensity : + 0.40 ± 0.14 m/s2 ) while time spent sitting decreased ( Δ sitting time : -128 ± 15 min/day ) compared to baseline ( all : p < 0.01 ) as well as compared to controls ( all : p < 0.01 ) . Furthermore , 6MWD significantly increased compared to baseline ( Δ 6MWD : + 79 ± 28 meters ) as well as compared to controls ( both : p < 0.01 ) . These significant improvements were sustained six and nine months after baseline . In contrast , controls showed unchanged daily physical activities and 6MWD compared to baseline for all time points . Conclusions Nordic Walking is a feasible , simple and effective physical training modality in COPD . In addition , Nordic Walking has proven to positively impact the daily physical activity pattern of COPD patients under short- and long-term observation .
