Detailed Description
The clinical case definition of post-COVID-19 condition (also referred to as Long COVID) as defined by the World Health Organization (WHO) includes individuals with a history of probable or confirmed SARS-CoV-2 infection, usually 3 months from the onset of COVID-19 with symptoms and that last for at least 2 months and cannot be explained by an alternative diagnosis. Fatigue represents one of the most frequently reported symptoms in individuals experiencing post-COVID-19 (i.e., post-COVID-19 fatigue; PCF).Fatigue is shown to persist for months after SARS-CoV-2 infection, negatively impacting activities of daily living. For the purposes of this SPiRE proposal, fatigue is operationally defined as a state characteristic encompassing a subjective lack of physical and/or mental energy that is perceived by the individual to interfere with usual or desired activities.
Increased fatigability is a possible complication following SARS-CoV-2 infection due to the presence of both neuromuscular and neurobiological consequences. Skeletal muscle alterations including reduced force capacity, fiber atrophy, mitochondria and metabolic dysfunction, and capillary impairments have been observed in patients following SARS-CoV-2 infection. Autopsy reports of patients who died after SARS-CoV-2 infection found evidence of skeletal muscle atrophy of type 2 fibers, necrotizing myopathy, and myositis. Similarly, using nerve conduction studies, patients with long-term COVID-19 were found to have signs of myopathy, even those who were not hospitalized. Evidence from cardiopulmonary exercise testing in patients diagnosed with COVID-19 has revealed impaired skeletal muscle oxygen extraction, as opposed to central limitations (i.e., cardiac output), as a determinant of exercise intolerance. In addition to neuromuscular complications, SARS-CoV-2 infection has also been shown to be associated with psychiatric sequelae. Collectively, these findings underscore neuromuscular as well as neurobiological consequences of SARS-CoV-2 as potential independent or co-occurring mechanisms by which increased fatigability occurs and persists.
Despite widespread calls for the importance of rehabilitation in individuals recovering from SARS-CoV-2 infection, little progress has been made regarding the potential benefits of physical exercise on fatigue and fatigability in this population. Moreover, concerns have been raised about the applicability of physical exercise in patients recovering from SARS-CoV-2 infection. For example, while the health and functional benefits of exercise are vast and widely known, in certain patient populations exertion is shown to exacerbate symptom severity. Some individuals with PCF may report experiencing worsening of symptoms after physical or mental exertion. Home-based exercise may offer an appealing option for those individuals concerned about attending community fitness facilities. Home-based exercise is shown to produced moderate effects on muscle strength and balance. Presently, the exact dosing of home-based exercise to elicit positive outcomes in fatigability is unknown. Minimal-dose resistance exercise has been proposed as a potential strategy for improving neuromuscular characteristics and physical function. Minimal-dose resistance exercise uses little to no equipment with exercises performed at lower workloads. The investigators aim to adapt the "minimal-dose" resistance exercise paradigm to a remote home-based resistance exercise program for Veterans with PCF to determine its implications for reducing fatigability and improving neuromuscular and neurobiological factors. Minimal-dose resistance exercise for the proposed application is defined as a single, weekly body-weight exercise session.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Performance fatigability
Time Frame: baseline and week 8
|
Performance fatigability will be assessed as change in maximal voluntary isometric contraction (MVIC) torque of the dominant leg.
Change in MVIC torque from the initial MVIC contraction to the last MVIC contraction will be used to determine the Performance Fatigability index.
