This will also include photovoice and photo-elicitation. Demographic information will be recorded and participants will also complete several respiratory symptom questionnaires.Phase 2:Participants will take part in physical activity testing before and after pulmonary rehabilitation while wearing physical activity monitors. Demographic information will be recorded and participants will also complete several respiratory symptom and physical activity questionnaires. Participants will also wear the physical activity monitors for 8 days after the pre-testing sessions and after their final pulmonary rehabilitation class.Sub-study:Participants will be asked to take images of barriers during physical activity, facilitators during physical activity, feelings during physical activity and types of physical activity they take part in for 8 days after their final pulmonary rehabilitation class. Participants will then take part in a semi-structured interview about the images their have taken while doing physical activity., conditionsModule conditions: Chronic Obstructive Pulmonary Disease, designModule studyType: OBSERVATIONAL, designInfo observationalModel: COHORT, timePerspective: PROSPECTIVE, enrollmentInfo count: 70, type: ESTIMATED, armsInterventionsModule, outcomesModule primaryOutcomes measure: Phase 1 - Semi-structured Interviews, primaryOutcomes measure: Phase 2 - Differences between time spent in PA intensity expressed in absolute and relative intensity., secondaryOutcomes measure: Phase 1 - Medical Research Council (MRC) Dyspnoea Scale, secondaryOutcomes measure: Phase 1 - COPD Assessment Test (CAT), secondaryOutcomes measure: Phase 1 - Chronic Respiratory Questionnaire (CRQ-SR), secondaryOutcomes measure: Phase 1 - Photovoice and photo-elicitation, secondaryOutcomes measure: Phase 2 - Medical Research Council (MRC) Dyspnoea Scale, secondaryOutcomes measure: Phase 2 - COPD Assessment Test (CAT), secondaryOutcomes measure: Phase 2 - Chronic Respiratory Questionnaire (CRQ-SR), secondaryOutcomes measure: Phase 2 - Gait Analysis, secondaryOutcomes measure: Phase 2 - Exercise Capacity (ISWT), secondaryOutcomes measure: Phase 2 - Exercise Capacity (ESWT), secondaryOutcomes measure: Daily PROactive Physical Activity instrument in COPD (D-PPAC), secondaryOutcomes measure: Phase 2 - Photovoice and photo-elicitation, eligibilityModule sex: ALL, minimumAge: 40 Years, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: NIHR Leicester Biomedical Research Centre - Respiratory, status: RECRUITING, city: Leicester, state: Leicestershire, zip: LE67 2DU, country: United Kingdom, contacts name: Phoebe H Lloyd-Evans, role: CONTACT, phone: +441162502758, email: phile1@leicester.ac.uk, contacts name: Mark W Orme, role: CONTACT, email: mwo4@leicester.ac.uk, contacts name: Mark W Orme, role: PRINCIPAL_INVESTIGATOR, geoPoint lat: 52.6386, lon: -1.13169, hasResults: False
