Nitrate and Exercise Performance in Middle to Older Aged Adults
Completed · Not applicable
Conditions studied: Aging
In brief
Research with young healthy individuals has shown that beetroot juice beverages that contain large amounts of nitrate can improve exercise performance. Currently, it is not know whether the consumption of beetroot juice beverages high in nitrate can improve exercise performance in higher functioning middle- to older-aged adults. Therefore, the purpose of this study is to compare the effect of two different beetroot juice beverages (one high in nitrate and one low in nitrate) on exercise performance in middle- to older-aged adults.
