Drinking beetroot juice before a workout could enhance the benefits of exercise training in postmenopausal women, according to new research. Reduced nitric oxide availability may diminish the responsiveness of skeletal muscles and blood vessels during exercise, potentially explaining why late postmenopausal women respond differently to exercise training. To address these challenges, the researchers investigated whether beetroot juice, rich in dietary nitrate, could enhance the health benefits of exercise for late postmenopausal women. Nitrate is stored in limited amounts in skeletal muscle and converted to nitric oxide during physical exertion. For the study, 24 postmenopausal volunteers completed supervised, circuit-based exercise training...
