Remote Exercise to Improve Physical Activity Levels and Markers of Heart Health in Cystic Fibrosis (RHH-CF)

With advances in genetic therapies, many people with Cystic Fibrosis (CF) are living longer. With the improvement in life expectancy has emerged an increased risk of cardiovascular disease (CVD). Factors such as insulin resistance, reduced physical activity, rising blood pressure from newer medications, and changes in body mass index have made cardiovascular health a growing concern in CF care. This study aims to assess whether a remotely delivered, monitored exercise programme can increase physical activity levels in adults with CF. Secondary outcomes will explore whether the intervention improves key CVD risk factors. Participants will be randomly assigned to either a control group or an intervention group, which will complete an 8-week home-based aerobic and resistance exercise programme. Exercise intensity will be tailored using the Rate of Perceived Exertion scale. Key outcomes include weekly physical activity levels, body mass index, waist circumference, lung function (spirometry) and blood biomarkers. Home-based capillary blood tests, analysed pre- and post-intervention, will measure cholesterol, lipid profiles, inflammation and other relevant hormones.
