Research summary
Physical activity (PA) helps prevent and manage non-communicable diseases such as chronic obstructive pulmonary disease (COPD). Pulmonary rehabilitation (PR) has been shown to benefit people living with COPD by reducing breathlessness, increasing muscle strength, and improving the management of exacerbations. However, the improvement in PA in individuals with COPD remains inconsistent following PR. Despite the personalised nature of PA prescription during PR, the evaluation of free-living PA data has been limited to a ‘one size fits all’ approach using absolute intensity categories. Reduced exercise tolerance can result in PA being perceived at a high intensity relative to a person’s exercise capacity, despite the absolute intensity being low. Exploring both the relative and absolute intensity of PA could offer additional insights and clinical relevance for the evaluation of physical activity in COPD populations. The aim of this PhD is to translate the principle of individualised exercise prescription into the evaluation of daily absolute and relative intensity PA in a user-friendly format for PR teams and service users.
