Mild to moderate post-COVID- 19 alters markers of lymphocyte activation, exhaustion, and immunometabolic responses that can be partially associated by physical activity level— an observational sub-analysis fit- COVID study

Physical activity status seems to be protective against the severe form of SARS-CoV-2, reducing risk of  hospitalization and worsened clinical outcome. However, the impact of physical activity after mild-to-moderate COVID-19 episode on immune and metabolic profiles is unknown. Therefore, this study aimed to evaluate if physical activity is associated with systemic and
cellular immunometabolic responses, in young adults after mild-to-moderate COVID-19 infection. Patients previously infected with COVID-19 and healthy controls were recruited for this cross-sectional observational study.
