Benefits of beetroot supplementation on maximal exercise, blood pressure, and the redox state of blood

Abstract (Summary)

This study investigated the effects of acute versus chronic beetroot supplementation on maximal exercise, resting blood pressure, nitrates, oxidative stress (TBARS), and antioxidant capacity (SOD) in the blood. Thirty participants were placed in one of three groups; consuming beetroot for 7 days (BR7), 1 day (BR1), or the Control. Data was analyzed using ANOVA and t-test (p < 0.05). There were no changes in maximal exercise or blood pressure after supplementation. Nitrate levels increased significantly after 7 days of beetroot consumption (p = 0.04) but not after a single dose. Additionally, both a prolonged use and a single dose of beetroot supplementation increased antioxidant capacity (p = 0.02). Long term beetroot consumption minimized the normal exercise response in both nitrate levels and SOD activity. TBARS varied by group. This study suggests that the potential for increased lipid peroxidation associated with beetroot supplementation appeared to be mitigated by increased antioxidant capacity.
