| Abstract | Failure to recover following severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) may have a profound impact on individuals who participate in high-intensity/volume exercise as part of their occupation/recreation. The aim of this study was to describe the longitudinal cardiopulmonary exercise function, fatigue, and mental health status of military-trained individuals (up to 12-mo postinfection) who feel recovered, and those with persistent symptoms from two acute disease severity groups (hospitalized and community-managed), compared with an age-, sex-, and job role-matched control. Eighty-eight participants underwent cardiopulmonary functional tests at baseline (5 mo following acute illness) and 12 mo; 25 hospitalized with persistent symptoms (hospitalized-symptomatic), 6 hospitalized and recovered (hospitalized-recovered); 28 community-managed with persistent symptoms (community-symptomatic); 12 community-managed, now recovered (community-recovered), and 17 controls. Cardiopulmonary exercise function and mental health status were comparable between the 5 and 12-mo follow-up. At 12 mo, symptoms of fatigue (48% and 46%) and shortness of breath (SoB; 52% and 43%) remain high in hospitalized-symptomatic and community-symptomatic groups, respectively. At 12 mo, COVID-19-exposed participants had a reduced capacity for work at anaerobic threshold and at peak exercise levels of deconditioning persist, with many individuals struggling to return to strenuous activity. The prevalence considered "fully fit" at 12 mo was lowest in symptomatic groups (hospitalized-symptomatic, 4%; hospitalized-recovered, 50%; community-symptomatic, 18%; community-recovered, 82%; control, 82%) and 49% of COVID-19-exposed participants remained medically nondeployable within the British Armed Forces. For hospitalized and symptomatic individuals, cardiopulmonary exercise profiles are consistent with impaired metabolic efficiency and deconditioning at 12 mo postacute illness. The long-term deployability status of COVID-19-exposed military personnel is uncertain. |
