Brief summary
THis study aims to examine PA trajectory, and potential behaviour-change factors least 12 months after COVID-19, across different levels of acute disease severity, and specifically in people with and without Long COVID.
Detailed description
Eligible participants will be contacted and invited for a first visit by a pulmonologist or a respiratory physiotherapist, during which those interested will provide informed consent. Participants will be interviewed and medical records reviewed to collect sociodemographic, anthropometric, and clinical data. Then, functional capacity, peripheral muscle strength, and lung function will be assessed using several tests, and dyspnoea, fatigue, anxiety, depression, and HRQoL through self-administrated questionnaires. Finally, people will be provided with a specific device and instructed on its use for measuring daily PA over one week. A pulmonologist, specialized nurse, or technician from the corresponding centre will perform and assess spirometry, while two respiratory physiotherapists will conduct and supervise all other tests in a reserved space at the same centre. The assessments were scheduled at three time points: at least 12 months after hospital/medical discharge (baseline), three and six months afterward.
Interventions
BEHAVIORALPhysical activity
We will assess physical activity patterns of patients at baseline (at discharge from hospital or at patients' home), at 12 weeks and 6 months, through an objective measurement (triaxial accelerometer).

Inclusion criteria
* At least, 18 years of age; * Diagnosis with COVID-19; * Stable condition at hospital discharge or after 21 days of being treated at home (needed time to recover from an acute respiratory infection; however, patients treated at home should report a negative result in polymerase chain reaction \[PCR\] test). Those reporting clinically relevant symptoms among dyspnoea, fatigue, anxiety, depression or impaired health-related quality of life will be considered affected from post-COVID-19 condition or Long COVID.
Exclusion criteria
* Presence of signs of cognitive impairment or significant cardiovascular, neurological, and/or musculoskeletal disease, which may prevent the assessment tests and therefore limit participation. In particular, reasons for exclusion will be the following: cognitive disorders, such as sequelae of Alzheimer's disease, senile dementia; comprehension disorders, such as Wernicke's aphasia; cognitive-motor disorders, such as hemiparesis/hemiplegia due to stroke; musculoskeletal disorders, such as unconsolidated fractures, external prostheses (including replacements in amputees); cardiovascular disorders, such as unstable angina, recent acute myocardial infarction, among others. * Vacination before infection. * Reinfections during follow-up.

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Forced vital capacity (FVC) assessed using spirometry at baseline (at hospital discharge or patient's home) | Baseline | Forced vital capacity (FVC, milliliters) |
| Sociodemographics (sex) at baseline (at hospital discharge or patient's home) | Baseline | Sociodemographics (sex, assessed as male/female). |
| Ratio between Forced expiratory volume in the first second and Forced vital capacity (FEV1/FVC) assessed using spirometry at baseline (at hospital discharge or patient's home) | Baseline | Ratio between Forced expiratory volume in the first second and Forced vital capacity (FEV1/FVC, percentage) |
| Change in isometric quadriceps strength from baseline (at hospital discharge or patient's home) at 12 weeks and 6 months | Baseline, 12 weeks and 6 months | Isometric quadriceps strength (dynamometer). A hand-held dynamometer will be used to assess isometric strength of both legs. Participants will be seated at the edge of a treatment table, positioned near their maximal knee extension (0º), and with arms across the chest. The dynamometer will be positioned two fingers width above the lateral malleolus on the anterior aspect of the tibia. Four warm-ups will be allowed, on each at 25, 50, 75, and 100% of perceived effort, gradually building up to a maximal effort over 1 to 2 seconds. The tester will perform two make tests with the subject exerting 100% effort for 3 seconds. Average peak force of the two trials will be used to determine quadriceps muscle performance. The make test will entail the examiner giving appropriate resistance to the muscle force in order to ensure isometric conditions. After allowing 1 minute of rest, the procedure will be repeated at 60º of knee flexion. |
| Anthropometrics (height) at baseline (at hospital discharge or patient's home) | Baseline | Anthropometrics (height in meters). |
| Change in anthropometrics (weight) from baseline (at hospital discharge or patient's home) at 12 weeks and 6 months | Baseline, 12 weeks and 6 months | Anthropometrics (weight in kilograms). |
| Relevant clinical history (diagnosis with lung or cardiovascular disease) at baseline | Baseline | We will report the presence of any relevant clinical history related to lung or cardiovascular disease, cardiovascular risk or immunosuppressed status (for instance, due to cancer treatment or other pathology). |
| Sociodemographics (age) at baseline (at hospital discharge or patient's home) | Baseline | Sociodemographics (age in years). |
| Change in handgrip force from baseline (at hospital discharge or patient's home) at 12 weeks and 6 months | Baseline, 12 weeks and 6 months | Handgrip force (dynamometer). A hand-held dynamometer will be used to measure isometric strength of the grip. Participants will be seated on a straight back chair with both feet flat on the floor. Arm positioning will be demonstrated by the examiner: the tested arm will have the elbow bended to 90º, the forearm and wrist in neutral position, and the fingers flexed as needed for a maximal contraction, while the not-tested arm will assume an adducted and neutrally rotated shoulder position. Subjects will be instructed to breathe in through their nose and blow out through pursed lips while making a maximum grip effort. At this time, a verbal encouragement will be given by the examiner (e.g., Squeeze! Harder! Harder! Relax!). Four minutes or more of rest will be allowed between each grip assessment. The average score among 3 trials will be recorded. |
| Change in maximal inspiratory and expiratory pressures from baseline (at hospital discharge or patient's home) at 12 weeks and 6 months | Baseline, 12 weeks and 6 months | Maximal respiratory pressures will be measured using a specific device; then, the highest value of 3 attempts will be selected to obtain a reliable average, excluding pressure peaks lower than one second. Participants will be asked to sit with their neck and chest in an upright position and their feet flat on the floor. The results will be read using the reference values provided by Black and Hyatt equations. |
| Change in health-related quality of life from baseline (at hospital discharge or patient's home) at 12 weeks and 6 months | Baseline, 12 weeks and 6 months | Health-related quality of life (EQ-5D-5L questionnaire). The EQ-5D-5L consists of two parts: the descriptive system and a visual analogue scale (VAS). The descriptive system addresses five different dimensions (mobility, self-care, usual activities. pain/discomfort, and anxiety/depression), each with a five-point Likert-scale; the answering pattern can be transferred to a utility between 0 and 1 (the higher the better) by distinct (nation-specific) scoring algorithms. On the other hand, the VAS allows valuing current health on a 0-100 mm scale, with higher values indicating better health. |
| Change in dyspnea symptom from baseline (at hospital discharge or patient's home) at 12 weeks and 6 months | Baseline, 12 weeks and 6 months | Dyspnea - modified Medical Research Council (mMRC) scale. The mMRC dyspnea scale consists of five grades of increasing severity. A higher score indicates a greater impact of dyspnea on activities of daily life. |
| Change in fatigue symptom from baseline (at hospital discharge or patient's home) at 12 weeks and 6 months | Baseline, 12 weeks and 6 months | Fatigue - Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale. The FACIT-F scale consists of many items to produce a global score, and each item can be scored from 0 to 4 (from not at all to very much). It covers different aspects of fatigue (physical, functional, emotional, and social consequences) with regard to the previous seven days. A higher score reflects less fatigue. |
| Change in anxiety and depression symptoms from baseline (at hospital discharge or patient's home) at 12 weeks and 6 months | Baseline, 12 weeks and 6 months | Anxiety and depression-The Hospital Anxiety and Depression Scale (HADS). The HADS consists of two subscales (HADS-A, for anxiety disorders, and HADS-D, for depression) both containing seven intermingled items. A higher score implies a more severe case. |
| Forced expiratory volume in the first second (FEV1) assessed using spirometry at baseline (at hospital discharge or patient's home) | Baseline | Forced expiratory volume in the first second (FEV1, milliliters) |
