Developing Personalised Relative Physical Activity Thresholds in COPD.

Phase 1 - Semi-structured Interviews,Phase 2 - Differences between time spent in PA intensity expressed in absolute and relative intensity.

The aim of this observational study is to translate the principle of individualised exercise
 prescription into the evaluation of daily absolute and relative intensity physical activity.
 
 The main questions this study aims to answer are:
 
 - Phase 1: What does physical activity (intensity) mean to people with COPD?
 
 - Phase 2: Are there differences between time spent in absolute and relative physical
 activity for people with COPD?
 
 Phase 1 Participants will take part in semi-structured interview (30-45 minutes) about living
 with COPD and perceptions of physical activity and how they perceive intensity. 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.
