Introduction – The pandemic spread of SARS-CoV-2 has led to an unprecedented outbreak of viral pneumonia. Despite the current focus of worldwide research being the characterization of post-COVID-19 sequelae, the level of functional impact that this disease causes in the elderly who have presented moderate, severe, or critical manifestations is still unknown. Objective – To identify the main sequelae on functional respiratory capacity in elderly people after COVID-19. Methods – A cross-sectional study was carried out in the community. Functional aerobic capacity (2-min step test), dyspnea (modified Medical Research Council Dyspnea Questionnaire), respiratory and peripheral muscle strength (maximum inspiratory and expiratory pressure, grip strength), and the Frailty Index (Clinical Fragility Scale) were assessed in 25 individuals aged ≥65 years, living in the community who have had a diagnosis of COVID-19 for up to six months, and in an equal number of elderly people with the same characteristics without a known diagnosis of COVID-19. Results – The elderly with a diagnosis of COVID-19 up to six months presented a decrease in the values ​​of maximum inspiratory pressure (p=0.001) and maximum expiratory pressure (p=0.015), in aerobic capacity (p<0.001) with significant presence of exertion induced desaturation (p<0.001), and increased values ​​of dyspnea perception (p=0.001) and Frailty Index (p=0.026). Conclusion – Significant changes were found in the functional respiratory capacity of elderly patients diagnosed with COVID-19 for up to six months when compared with elderly individuals without a known diagnosis of COVID-19. These results may be an important indicator in the characterization of sequelae in the elderly after infection by SARS-CoV-2.
