Conditions
Summary
Exercise training as part of a structured pulmonary rehabilitation program is a key factor in improving quality of life and symptoms in people with interstitial lung disease (ILD). Optimal methods of exercise training are yet to be explored in ILD. Drinking beetroot juice, which is rich in nitrate, has been shown to improve exercise performance in a variety of groups, but its effects in ILD have not been tested. The purpose of this study is to determine if drinking nitrate-rich beetroot juice can improve exercise performance compared to drinking nitrate-free beetroot juice in people with ILD.
