This study will test the efficacy of treadmill exercise combined with supplemental oxygen during exercise and recovery for the treatment of persistent post-acute COVID-19 symptoms. Participants will be pseudo-randomized (stratified by age) to one of four conditions for 8 treatment sessions: 1) treadmill exercise plus supplemental oxygen, 2) treadmill exercise plus air, 3) supplemental oxygen only, 4) air only. All participants will then cross-over and receive 16 additional sessions of treadmill exercise plus supplemental oxygen.
This study will test the efficacy of a COVID-19 specific cardiopulmonary rehabilitation protocol for treatment of persistent post-acute COVID symptoms and to study the impact of cardiopulmonary improvement on cognition, mental health, and function. Participants (N=36) with persistent post-acute COVID symptoms will undergo pre-treatment neurocognitive, orthostatic tolerance, and exercise tolerance tests before being pseudo-randomized (stratified by age and sex) to one of four conditions (all of which occur twice a week): 1) 8 sessions of treadmill exercise plus supplemental oxygen, 2) 8 sessions of treadmill exercise plus air, 3) 8 sessions of supplemental oxygen only, and 4) 8 sessions of air only. The pre-treatment testing will be repeated, after which all participants will receive 16 additional sessions of treadmill exercise plus supplemental oxygen, followed by post-treatment testing. All participants will complete baseline measures of physical and mental health, physical function, emotional wellbeing, and coping. A brief symptom measure will be collected daily and physical function, mental health, and emotional wellbeing will be assessed weekly.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Treadmill Exercise with Supplemental Oxygen | Experimental | Participants will receive 24 sessions (2 x week for 12 weeks) of treadmill exercise combined with 6 liters per minute of supplemental oxygen via nasal cannula during exercise and 5-minutes of recovery. The first treadmill session will last 25% longer than the exercise tolerance test, but at a lower intensity, such that 80-100% of peak exercise intensity calculated from the exercise tolerance test MET is achieved within three sessions, after which time and intensity will be increased by no more than 0.5 METS, as tolerated based on symptoms and vitals. Heart rate, rhythm, and oxygen saturation will be continuously monitored, and blood pressure readings will be obtained every three to five minutes. |
|
| Treadmill Exercise with Air | Sham Comparator | Participants will receive 8 sessions (2 x week for 4 weeks) of treadmill exercise combined with air delivered via nasal cannula during exercise and 5-minutes of recovery. They will then cross-over to 16 sessions of treadmill exercise combined with 6 liters per minute of supplemental oxygen via nasal cannula during exercise and 5-minutes of recovery. The first treadmill session will last 25% longer than the exercise tolerance test, but at a lower intensity, such that 80-100% of peak exercise intensity calculated from the exercise tolerance test MET is achieved within three sessions, after which time and intensity will be increased by no more than 0.5 METS, as tolerated based on symptoms and vitals. Heart rate, rhythm, and oxygen saturation will be continuously monitored, and blood pressure readings will be obtained every three to five minutes. |

| Activity metabolic equivalent of task (MET) tolerated | MET will be computed based upon peak exercise speed (MPH) and incline % gradation). Scores are expected to range from 1.8 to 12.1 (but can be higher is speed exceeds 3.9 MPH). Higher METs indicate more energy output. | Up to 24-weeks |
| Breathlessness | Breathlessness will be assessed during peak exercise via self-report using the Borg Dyspnea scale. Scores can range from 0 to 20 and higher scores indicate more breathlessness | Up to 24-weeks |
| Rate of perceived exertion (RPE) | RPE will be assessed during peak exercise via self-report using the Borg RPE scale. Scores can range from 0 to 20 and higher scores indicate more RPE. | Up to 24-weeks |
| Cognition (attention, short, delayed, and working memory, verbal fluency, and abstraction). | Cognition will be assessed with the Repeatable Battery for the Assessment of Neuropsychological Status Update (RBANS-U) List Learning, List Recall, List Recognition, Story Memory, Story Recall, Semantic Fluency and Picture Naming subtests and the Wechsler Adult Intelligence Scale - Fourth Edition (WAIS-IV) Similarities and Digit Span subtests. All scores will be standard scores based on age norms. |
| Measure | Description | Time Frame |
|---|---|---|
| Depression | Depression will be measured weekly with the Center for Epidemiological Studies Depression Scale - Revised (CESD-R). Scores range from 0 to 60 and higher scores indicate greater depression severity. | Up to 24-weeks |
| Generalized anxiety |
