Beetroot Supplementation in Women Enjoying Exercise Together

Completed · Not applicable

Conditions studied: Aging, Postmenopause, Obesity

In brief

This study seeks to determine the feasibility of an exercise training progression with the consumption of beetroot juice prior to exercise in postmenopausal women. Results from this investigation will be used to determine preliminary effect sizes for exercise training only (control) and exercise training + beetroot juice (EX+BR) to inform the direction of larger randomized clinical trials on pre-post changes in measures of cardiovascular health and endothelial function.
