Investigating the effects of beetroot on lung function in COVID-19 survivors

Assessment of Ventilatory Efficacy in Patients With Fatigue Associated With SARS-CoV2 Infection After Ingestion of Beet Juice

NA · Hospital de Mataró · NCT06217211

This study is testing if taking beetroot can help improve lung function and energy levels in people who are feeling tired and short of breath after recovering from COVID-19.

What this trial studies

This study aims to explore the impact of beetroot supplementation on lung function and muscle efficiency in patients experiencing fatigue after recovering from SARS-CoV-2 infection. It focuses on individuals who exhibit persistent symptoms, particularly dyspnea and fatigue, which are not of pulmonary origin but significantly affect their daily functionality. The methodology includes assessing mechanical efficiency through incremental exercise tests and analyzing muscle biopsies to understand the underlying physiological changes. The goal is to determine if beetroot can improve ventilation and overall physical performance in these patients.

Who should consider this trial

Good fit: Ideal candidates are individuals who have experienced fatigue following a SARS-CoV-2 infection and are willing to provide informed consent.

Not a fit: Patients with pre-existing cardiovascular, oncological, or neuromuscular conditions, or those with significant alcoholism or severe malnutrition, may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could enhance lung function and reduce fatigue in COVID-19 survivors, improving their quality of life.

How similar studies have performed: While the approach of using beetroot for improving muscle efficiency is novel in the context of post-COVID fatigue, similar interventions have shown promise in other conditions related to muscle performance.
