Beetroot extract has gained attention for its potential benefits for cardiovascular health, particularly in the context of exercise and blood pressure. Here are five studies that investigate the effects of beetroot extract on blood pressure and exercise:
Study Title: "Beetroot juice and exercise: pharmacodynamic and dose-response relationships" (Link: https://www.ncbi.nlm.nih.gov/pubmed/23839191)
Summary: This study investigated the dose-response relationship between beetroot juice supplementation and exercise performance and blood pressure in healthy adults. The authors found that higher doses of beetroot juice led to greater improvements in exercise performance and blood pressure, suggesting that beetroot juice may have potential as an ergogenic aid and blood pressure-lowering agent.
Study Title: "Effect of beetroot juice on lowering blood pressure in free-living, disease-free adults: a randomized, placebo-controlled trial" (Link: https://www.ncbi.nlm.nih.gov/pubmed/23473470)
Summary: This randomized, double-blind, placebo-controlled trial investigated the effects of beetroot juice supplementation on blood pressure in healthy adults. The authors found that beetroot juice supplementation significantly reduced systolic blood pressure compared to placebo, suggesting that beetroot juice may have potential as a dietary intervention for reducing blood pressure.
Study Title: "Beetroot juice supplementation improves high-intensity intermittent type exercise performance in trained soccer players" (Link: https://www.ncbi.nlm.nih.gov/pubmed/23842842)
Summary: This randomized, double-blind, placebo-controlled trial investigated the effects of beetroot juice supplementation on high-intensity intermittent exercise performance in trained soccer players. The authors found that beetroot juice supplementation improved exercise performance and reduced perceived exertion compared to placebo, suggesting that beetroot juice may have potential as an ergogenic aid for athletes.
Study Title: "Acute effect of a high nitrate diet on brain perfusion in older adults" (Link: https://www.ncbi.nlm.nih.gov/pubmed/25459980)
Summary: This study investigated the effects of a high-nitrate diet, which included beetroot juice, on brain perfusion in older adults. The authors found that the high-nitrate diet improved cerebral blood flow in several regions of the brain, suggesting that beetroot juice may have potential as a dietary intervention for promoting brain health.
Study Title: "Acute beetroot juice supplementation on sympathetic nerve activity: a randomized, double-blind, placebo-controlled proof-of-concept study" (Link: https://www.ncbi.nlm.nih.gov/pubmed/27716697)
Summary: This randomized, double-blind, placebo-controlled trial investigated the effects of beetroot juice supplementation on sympathetic nerve activity in healthy adults. The authors found that beetroot juice supplementation reduced sympathetic nerve activity, which is associated with cardiovascular disease risk, suggesting that beetroot juice may have potential as a dietary intervention for reducing cardiovascular disease risk.
