“…Standardized encouragement is given with monitoring of HR, SpO 2 , and number of steps recorded, and the test is ceased if the participant becomes too tired to continue or if SpO 2 falls below 75 % [61]. Individuals can change leading legs to minimize fatigue [58].…”

“…Desaturation occurred over a shorter time frame in the 3MST [61], suggesting the test induces a greater challenge to the respiratory system in CF compared to the 6MWT, particularly in children and adults with moderate to severe disease [16,63]. In contrast, a ceiling effect was evident in those with mild CF [61,63]. Of clinical importance is this tests' responsiveness to antibiotic therapy in children with CF [64] and its prediction of total hospital days over a 12-month period in adults who desaturated below 90 % during the test [16].…”

“…In patients with mild cystic fibrosis (CF) and in children and adults with moderate to severe disease, the 3MST is a reproducible test for physiological and symptom parameters [61], step number, and oxygen desaturation [16,61,62], which may be attributable to the external pacing. In children with CF, a greater maximum HR response was demonstrated with the 3MST compared to the 6MWT [61,62].…”

Assessment of exercise capacity and physical function is critical in individuals with respiratory conditions. While field walking tests are well-established measures of exercise capacity, alternative options involving walking of a shorter duration, stair or step climbing, and functional activities are also available. This review outlines these alternative tests and their relevant measurement properties, including comparisons with established field walking tests and their clinical applications. The 4-m gait speed and 30-m walking test are walking tests of shorter duration than traditional tests and may be a surrogate marker for exercise capacity. Stair climbing tests require greater body movement against gravity, often imposing a greater workload compared to field walking tests. Functional tests such as sit-to-stand tests provide information related to strength and general functioning. The current measurement properties established, together with the emerging evidence for responsiveness to interventions suggest potential for broader clinical use of these alternative field tests.
