The long-term consequences of COVID-19 are still unknown. This study aimed to investigate physical activity levels, respiratory and peripheral muscle strength, and pulmonary function in the long term in young adult COVID-19 patients who recovered from mild disease.MethodsThis cross-sectional study was carried out at least 6 months after the COVID-19 diagnosis, 54 patients with COVID-19 (median age: 20 years) and 46 controls (median age: 21 years) were compared. Functional status (post-COVID-19 functional status scale), respiratory (maximum inspiratory and expiratory pressures (MIP, MEP)) and peripheral muscle strength (dynamometer), pulmonary function (Spirometry), dyspnea and fatigue (modified Borg scale), and physical activity levels (International Physical Activity Questionnaire) were evaluated. ClinicalTrial number: NCT05381714.ResultsPatients with COVID-19 measured and percent predicted MIP and MEP were statistically decreased compared with the controls (p < 0.05). Shoulder abductors muscle strength (p < 0.001) and the number of individuals with low physical activity levels were significantly higher in patients compared with controls (p = 0.048). Pulmonary function, quadriceps muscle strength, exertional dyspnea, and fatigue scores were similar in groups (p > 0.05).ConclusionRespiratory and peripheral muscle strength and physical activity levels are adversely affected in patients with COVID-19, even though the patients were mildly affected in the long term. Also, symptoms such as dyspnea and fatigue may persist. Therefore, these parameters should be evaluated in the long term, even in young adults who are mildly affected by COVID-19.eninfo:eu-repo/semantics/openAccessCOVID-19Respiratory musclesPulmonary symptomsPhysical activityDyspneaArticle10.1007/s00508-023-02204-52-s2.0-851537535102599-1037115337Q2251135WOS:000978275100001Q2
