Introduction: Cystic fibrosis (CF) is a multisystem genetic disease characterized by thick secretions, progressive pulmonary damage, and functional decline. Among the main prognostic indicators are maximal oxygen uptake (VO₂peak) and forced expiratory volume in one second (FEV₁). Although physical exercise is recommended by clinical guidelines as part of comprehensive CF management, uncertainty remains regarding its objective impact, particularly on pulmonary function.
Objectives: To evaluate, through a systematic review of randomized controlled trials (RCTs) published since 2017, the effects of physical exercise on VO₂peak and FEV₁ in individuals with CF.
Methods: The PRISMA 2020 guidelines were followed. Included RCTs involved participants of any age diagnosed with CF, comparing exercise programs (aerobic, resistance, or combined) with standard care. Studies had to report pre- and post-intervention measures of VO₂peak and/or FEV₁. The literature search was updated through May 2025. Risk of bias was assessed using the Cochrane RoB 2 tool, and certainty of evidence was evaluated using the GRADE approach.
Results: A total of 13 RCTs were included (n = 392; ages 6 to 40 years). Most studies reported significant improvements in VO₂peak (increases of 5 to 15%) in the intervention groups. In contrast, no clinically meaningful changes in FEV₁ were observed. One multicenter study (ACTIVATE-CF) reported a transient FEV₁ improvement in the control group at six months.
Conclusions: Physical exercise consistently improves aerobic capacity in individuals with CF but does not produce significant changes in pulmonary function (FEV₁) in the short term.
