Endurance cycle ergometry tests performed at a sub‐maximal work rate elicit peak physiological and symptom responses in adults with cystic fibrosis

Time to symptom limitation (Tlim) achieved during constant work rate tests is considerably more responsive change than measures commonly recorded ramp-based tests, such as peak of oxygen uptake and maximal (Wmax). There limited literature on the use of, physiological responses to, cycle ergometry in people with cystic fibrosis (CF). The results this study provide evidence that test, when conducted at 80% Wmax, elicits appears be safe adults CF. For clinicians prescribing exercise an intensity approaching or equivalent Wmax a non-laboratory-based setting, consideration needs given level supervision patient monitoring required.
