About this trial
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.
Eligibility criteria
Qualifiers
Past diagnosis of Cystic Fibrosis confirmed via two copies of a faulty CFTR gene, or; previous sweat chloride test with a result >60mmol/L chloride, or; prescribed modulator therapy (Orkambi, Symkevi, Kaftrio);
Disqualifiers
Any reported condition, behaviour or reported use of substances which may pose undue personal risk to the participant or introduce bias into the study, except for any which are ubiquitous in society and so would be equally distributed between groups and/or therefore relevant to generalisation (e.g. caffeine)
Medications which increase risk of harm to a participant exercising remotely such as fluoroquinolone antibiotics, beta blockers, or blood pressure medication
Individuals with unstable or poorly controlled diabetes
Individuals on statins
