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 .
Energy balance in depleted ambulatory patients with chronic obstructive pulmonary disease: the effect of physical activity and oral nutritional supplementation.
Patients with chronic obstructive pulmonary disease ( COPD ) often suffer from weight loss . The aim of the present study was to gain insight into the energy balance of depleted ambulatory COPD patients , in relation to their habitual level of physical activity and consumption of oral nutritional supplements .  Clinical ly stable and weight-stable patients ( n 20 ; BMI 19.8+/- SD 2.0 kg/m2 ) were studied 1 and 3 months after rehabilitation or recovery in the clinic and were at r and om assigned to a control or intervention group with regard to nutritional supplementation .  Energy intake was measured with a 7 d food record .  Energy expenditure was estimated from a simultaneous 7 d assessment of physical activity with a tri-axial accelerometer for movement registration in combination with measured BMR . Body mass was measured at several time points . The body mass remained stable in both groups after 1 or 3 months and mean energy balances were comparable for both groups . The mean body-mass change between month 1 and 3 was negatively related to the mean physical activity level ( r -0.49 ; P=0.03 ) . Weight change over the 3 months was negatively associated with the physical activity level . These results suggest that knowledge about the individual physical activity level is necessary for the estimation of the energy need of the COPD patient
