Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Nitrate is a naturally-occurring substance found in foods, especially green leafy vegetables and beets. Increasing nitrate intake (by drinking beetroot juice (BRJ) has been shown to improve muscle function young and middle-aged subjects, athletes, and patients with heart failure. The purpose of this study is to determine whether dietary nitrate provides a similar benefit in older individuals, and if so, the optimal dose. We will be comparing the effects of ingesting BRJ containing a smaller or greater amount of nitrate versus the effects of a placebo (BRJ from which the nitrate has been removed).
