This research study is testing whether beetroot extract — a natural supplement containing compounds that may improve blood vessel function — can help reduce the stress exercise puts on your heart and improve oxygen delivery to your muscles. Researchers want to understand if this supplement works specifically for older women with high blood pressure who are exercising.
High blood pressure is a major health risk for older adults and can make exercise feel harder on the heart. Scientists have found that beetroot extract contains natural compounds that might help blood vessels work better, but they need to study whether this benefit applies to older women with high blood pressure during physical activity.

You will come in for four separate visits, spaced at least 2 days apart. During each visit, you'll either rest quietly or do a light aerobic exercise session, and you'll take either the beetroot extract supplement or a placebo (inactive pill) beforehand. Researchers will measure your blood pressure, take small blood samples to check stress markers, and use a special scanner on your muscle to see how much oxygen it's getting.
