Exercise testing is a feasible and cost-effective option for assessing exercise tolerance, fatigue, and dyspnea related to effort. Being that the Chester step test (CST) is a progressive, submaximal test for predicting aerobic capacity, it could be a good option to explore. This study aimed to determine the reproducibility of CST for assessing exertional desaturation and exercise capacity in patients post-COVID-19 disease. A cross-sectional study was conducted on post-COVID-19 patients. Two attempts of the CST were performed. The intraclass correlation coefficient (ICC) was used to assess agreement between the two tests. Forty-two symptomatic post-COVID-19 patients were included, the mean age was 53.8 ± 10.3 years, and 52% were female. There was no significant difference between both tests (p = 0.896). Twenty-four percent of participants (10 cases) had a clinically significant decrease in SpO2 at the first assessment, compared to 30.1% (13 cases) at the second, with no significant difference. An ICC of 0.993 (95% CI: 0.987 to 0.996) was obtained for the total number of steps in the CST. 2025-05-15T19:19:57Z 2025-05-15T19:19:57Z 2022-10 2022-12 info:eu-repo/semantics/article http://hdl.handle.net/20.500.14342/5179 https://doi.org/10.3390/ healthcare11010051 eng Healthcare, 2023, 11(1), 51 info:eu-repo/grantAgreement/MINECO/ISCIII i ERDF/PI21/0555 http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess © L'autor/a Attribution 4.0 International MDPI
