Thirty-two patients were randomly 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 \u2264 p \u2264 0.040), except for SA ( p = 0.781). Exercise capacity, muscle strength and HRQOL were increased at 3 and 6 months ( p \u2264 0.002) with no between-group differences (0.148 \u2264 p \u2264 0.987). No changes were observed in self-efficacy ( p = 0.899). A PA-focused behavioural intervention during and after PR may improve patients\u2019 PA levels. Further research is warranted to assess the sustainability of the findings.<\/jats:p>","DOI":"10.1177\/1479972315619574","type":"journal-article","created":{"date-parts":[[2015,12,24]],"date-time":"2015-12-24T20:24:03Z","timestamp":1450988643000},"page":"57-66","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":76,"title":["Walk2Bactive"],"prefix":"10.1177","volume":"13","author":[{"given":"Joana","family":"Cruz","sequence":"first","affiliation":[{"name":"Respiratory Research and Rehabilitation Laboratory (Lab 3R), School of Health Sciences, University of Aveiro (ESSUA), Campus Universit\u00e1rio de Santiago, Aveiro, Portugal"},{"name":"Center for Health Technology and Services Research (CINTESIS), School of Health Sciences, University of Aveiro (ESSUA), Campus Universit\u00e1rio de Santiago, Aveiro, Portugal"}]},{"given":"Dina","family":"Brooks","sequence":"additional","affiliation":[{"name":"Rehabilitation Science Institute and Department of Physical Therapy, University of Toronto, Toronto, ON, Canada"}]},{"given":"Alda","family":"Marques","sequence":"additional","affiliation":[{"name":"Respiratory Research and Rehabilitation Laboratory (Lab 3R), School of Health Sciences, University of Aveiro (ESSUA), Campus Universit\u00e1rio de Santiago, Aveiro, Portugal"},{"name":"Center for Health Technology and Services Research (CINTESIS), School of Health Sciences, University of Aveiro (ESSUA), Campus Universit\u00e1rio de Santiago, Aveiro, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2015,12,23]]},"reference":[{"key":"bibr1-1479972315619574","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.200407-855OC"},{"key":"bibr2-1479972315619574","doi-asserted-by":"publisher","DOI":"10.1378\/chest.10-2521"},{"key":"bibr3-1479972315619574","doi-asserted-by":"publisher","DOI":"10.1378\/chest.11-2014"},{"key":"bibr4-1479972315619574","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.201309-1634ST"},{"key":"bibr5-1479972315619574","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.200508-1211ST"},{"key":"bibr6-1479972315619574","doi-asserted-by":"publisher","DOI":"10.1016\/j.rmed.2012.08.016"},{"key":"bibr7-1479972315619574","doi-asserted-by":"publisher","DOI":"10.1097\/HCR.0b013e3181ebf2ef"},{"key":"bibr8-1479972315619574","doi-asserted-by":"publisher","DOI":"10.1378\/chest.07-2655"},{"key":"bibr9-1479972315619574","first-page":"332","volume":"12","author":"Wilson JJ","year":"2014","journal-title":"COPD"},{"key":"bibr10-1479972315619574","doi-asserted-by":"publisher","DOI":"10.1016\/j.rmed.2014.10.020"},{"key":"bibr11-1479972315619574","doi-asserted-by":"publisher","DOI":"10.1177\/1479972314552280"},{"key":"bibr12-1479972315619574","doi-asserted-by":"publisher","DOI":"10.1016\/j.pec.2005.02.005"},{"key":"bibr13-1479972315619574","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmr.2007.11.003"},{"key":"bibr14-1479972315619574","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.c332"},{"key":"bibr15-1479972315619574","unstructured":"Global Strategy for the Diagnosis Management and Prevention of COPD.
