Home-based Exercise in COVID-19 Survivors

Study Overview
=================
Brief Summary
-----------------
The physical inactivity promoted by the patient's hospitalization, including those infected with the coronavirus, can lead to an important health impairment, including atrophy and loss of muscle function. Thus, a prospective study will be conducted to assess the effect of a home-based exercise training program on health outcomes and quality of life in COVID-19 survivors.

Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Exercise group<br> | Other: Exercise training<br>* A 16 weeks parallel-group randomised controlled trial will be performed, in which covid-19 survivors patients will complete a telemonitored home-based exercise training program, 3 times per week. The training program will involve strength, aerobic, balance and flexibility exercises.<br>|
| No Intervention: Control group<br>The control group will receive all regular medical care and advice on healthy lifestyle including the promotion of recommended physical activity levels. | |
