What this trial studies

This study aims to compare the effects of inspiratory muscle training and high-intensity interval aerobic exercise training on patients recovering from COVID-19. It addresses common post-COVID symptoms such as dyspnea, fatigue, and decreased exercise capacity. The primary outcome will be measured through oxygen consumption during a cardiopulmonary exercise test, while secondary outcomes will include muscle oxygenation and physical activity levels. Participants will be divided into three groups: inspiratory muscle training, high-intensity interval training, and a control group.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 who have been diagnosed with COVID-19 and are willing to participate.

Not a fit: Patients with significant comorbidities or contraindications to exercise may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve recovery outcomes and quality of life for patients suffering from long-term effects of COVID-19.

How similar studies have performed: Previous studies have shown positive effects of inspiratory muscle training and aerobic exercise in patients with lung diseases, suggesting potential success for this approach.
