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 .
A lifestyle activity intervention in patients with chronic obstructive pulmonary disease.
BACKGROUND Chronic obstructive pulmonary disease ( COPD ) patients have lower levels of physical activity compared to age-matched controls , and they limit physical activities requiring normal exertion . Our purpose was to compare the effectiveness of a traditional exercise therapy ( TET ) program with a behavioral lifestyle activity program ( LAP ) in promoting physical activity . METHODS Moderate physical activity ( kcal/week ) was assessed in 176 COPD patients using the Community Health Activities Model for Seniors question naire . Patients were r and omized to either a  three month TET program that meet thrice weekly or a LAP . The LAP was design ed to teach behavioral skills that encouraged the daily accumulation of self-selected physical activities of at least moderate intensity . Interventionist contact was similar ( 36 h ) between the two groups . Patients were assessed at baseline and 3 , 6 and 12 months . RESULTS Compared to baseline values , self-reported moderate physical activity increased three months post-r and omization with no significant difference ( p = 0.99 ) found between the TET ( 2501 + /- 197 kcal/week ) and the LAP ( 2498 + /- 211 kcal/week ) . At 6 and 12 months post-r and omization , there were no significant differences ( p = 0.37 and 0.69 , respectively ) in self-reported levels of moderate physical activity between the TET ( 2210 + /- 187 and 2213 + /- 218 kcal/week , respectively ) and the LAP ( 2456 + /- 198 and 2342 + /- 232 kcal/week , respectively ) . CONCLUSION Although there was no difference between treatment groups , the TET and the LAP were both effective at in increasing moderate levels of physical activity at 3 months and maintaining moderate physical activity levels 12 months post-r and omization .
