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 .
Walk2Bactive: A randomised controlled trial of a physical activity-focused behavioural intervention beyond pulmonary rehabilitation in chronic obstructive pulmonary disease.
The aim of this study was to investigate the impact of a physical activity (PA)-focused behavioural intervention during and after  pulmonary rehabilitation ( PR ) on PA levels ( primary aim ) , health-related outcomes and self-efficacy ( secondary aims ) of patients with COPD . Thirty-two patients were r and omly assigned to an experimental group ( EG ) or control group ( CG ) . The EG received a PA-focused behavioural intervention during PR ( 3 months ) and follow-up support ( 3 months ) . The CG received PR ( 3 months ) . Daily PA was collected : number of steps ; time spent in moderate-to-vigorous PA ( MVPA ) , total PA and sedentary activities ( SA ) . Secondary outcomes comprised exercise capacity , muscle strength , health-related quality of life ( HRQOL ) and self-efficacy . Measures were collected at baseline , 3 and 6 months . Compared with the CG , the EG improved the number of steps ( p = 0.006 ) and time spent in MVPA ( p = 0.007 ) , total PA ( p = 0.014 ) and SA ( p = 0.018 ) at 3 months . Differences were maintained after follow-up support ( 0.025 ≤ p ≤ 0.040 ) , except for SA ( p = 0.781 ) . Exercise capacity , muscle strength and HRQOL were increased at 3 and 6 months ( p ≤ 0.002 ) with no between-group differences ( 0.148 ≤ p ≤ 0.987 ) . No changes were observed in self-efficacy ( p = 0.899 ) . A PA-focused behavioural intervention during and after PR may improve patients ' PA levels . Further research is warranted to assess the sustainability of the findings
