Cystic Fibrosis and Exercise

Cystic fibrosis (CF) is among the most common genetic diseases, affecting about 30,000 people in the Unites States alone. Due to a mutation in the CF transmembrane conductance regulator (CFTR) gene, patients experience deficiencies in their respiratory, digestive and reproductive systems, as well as problems with temperature regulation and fluid balance. Due to the abnormally high production of thick and sticky mucus, patients are more likely to grow bacteria and develop infections.

Various treatments acn help patients improve health, ease symptoms, and increase life expectancy for those with CF. Daily medication is an important part of treatment, while patients also need to undergo physiotherapy and respiratory training. Nutrition is also key in maximizing patients’ well-being, and most patients need to take enzymes and vitamin supplements.

CF symptoms can make it difficult for patients to exercise, but regular physical activity can have a significant impact in improving patients’ quality of life, as determined by recent studies on the topic.

Cystic fibrosis and exercise

“Physical exercise is recognized to have considerable clinical benefit for different disease proceses. Regular habitual activity is cardio protective and associated with a reduced morbidity and mortality for established cardiovascular disease. Pulmonary rehabilitation programmes for patients with chronic airways obstruction (COAD), of which exercise is a core component, are being enthusiastically researched for their potential therapeutic benefit,” explained the authors of the study “Exercise and cystic fibrosis,” A. K. Webb, FRCP, M. E. Dodd, MCSP, and J. Moorcroft, MRCP.

By engaging in exercise, the adrenergic and purinergic pathways of the body are activated, which are routes responsible for regulating the activity of ion channels on airway epithelia cells and sweat glands. This process is thought to result in systemic improvements as well as improvements in the pathophysiological ion dysregulation at a cellular level. According to the study “Exercise Is Medicine in Cystic Fibrosis,” the benefits of exercise in patients with cystic fibrosis include increased exercise tolerance, respiratory muscle endurance and sputum expectoration, reduced residual volume and rate of decline in pulmonary function, improvements in fluid balance and retention of serum electrolytes, as well as lower risk of death.

Exercise guidelines for CF patients

The Cystic Fibrosis Foundation (CFF) offers a guide called “Day-to-Day: Exercise and Cystic Fibrosis (CF)” that includes detailed recommendations for patients. The foundation reminds that anyone can exercise, but it is important for patients to discuss plans with their healthcare team and get advice and support. When planning exercise routines, there are three things that patients must keep in mind: whether a type of exercise is enjoyable and fits their schedule, if it connects them with friends and family, and if it is an exercise that helps strengthen the heart and lungs, or bones and muscles. For children, the CFF recommends a type of exercise that involves them in many types of activities, rewards them when they join group events, allows for active playtime on most days of the week, and helps to keep TV and video game time to a minimum.

For teenagers, the foundation believes activities that make them feel good around their peers are preferable, as they are more likely to stick with a regular activity program that increases self-esteem. Adults are advised to pick a comfortable and enjoyable activity that continually exercises the heart and lungs, to find an exercise partner, do a variety of activities, choose activities that fit their lifestyle, pick lifetime activities like running and biking, find some activities that aren’t extremely competitive, and to set fair yet challenging goals.

For specific types of exercise or best times to perform them, it is important that patients seek professional help and advice.
