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 .
Self-efficacy enhancing intervention increases light physical activity in people with chronic obstructive pulmonary disease
Background People with chronic obstructive pulmonary disease lead sedentary lives and could benefit from increasing their physical activity . The purpose of this study was to determine if an exercise-specific self-efficacy enhancing intervention could increase physical activity and functional performance when delivered in the context of 4 months of upper body resistance training with a 12-month follow-up . Methods In this r and omized controlled trial , subjects were assigned to : exercise-specific self-efficacy enhancing intervention with upper body resistance training ( SE-UBR ) , health education with upper body resistance training ( ED-UBR ) , or health education with gentle chair exercises ( ED-Chair ) . Physical activity was measured with an accelerometer and functional performance was measured with the Functional Performance Inventory . Forty-nine people with moderate to severe chronic obstructive pulmonary disease completed 4 months of training and provided valid accelerometry data , and 34 also provided accelerometry data at 12 months of follow-up . The self-efficacy enhancing intervention emphasized meeting physical activity guidelines and increasing moderate-to-vigorous physical activity . Results Differences were observed in light physical activity ( LPA ) after 4 months of training , time by group interaction effect ( P=0.045 ) . The SE-UBR group increased time spent in LPA by + 20.68±29.30 minutes/day and the other groups decreased time spent in LPA by −22.43±47.88 minutes/day and -25.73±51.76 minutes/day . Changes in LPA were not sustained at 12-month follow-up . There were no significant changes in moderate-to-vigorous physical activity , sedentary time , or functional performance . Subjects spent most of their waking hours sedentary : 72%±9 % for SE-UBR , 68%±10 % for ED-UBR , and 74%±9 % for ED-Chair . Conclusion The self-efficacy enhancing intervention produced a modest short-term increase in LPA . Further work is needed to increase the magnitude and duration of effect , possibly by targeting LPA
