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...

Beetroot shows it can provide a competitive edge when playing sport. Evaluating the performance effects of foods that are thought to have a beneficial effect on aerobic performance, researchers found that beetroot, grapes, sour cherries, and pine bark extract, which contribute to nitric oxide availability in the body, boost endurance exercise performance. The meta-analysis evaluated the effect of consuming nitrate-rich foods (typically green leafy vegetables), foods that contain polyphenols (such as berries, cherries and cocoa), and L-Citrulline (found in watermelon) on exercise endurance performance. The study found that the nitrate levels contained in beetroot, which have been shown to boost...

Is beetroot the latest superfood? Beetroot may help reduce blood pressure but is it really a miracle cure? By Rose Prince 03 Sep 2009 Pass a packet of wine gums around, and everyone takes the red one. Confectioners know that colour sells – it always has, long before sweets were invented. Cherries, raspberries, blackcurrants and grapes have always been irresistible. But, if Mother Nature made healthy foods red in order to encourage us to eat more of them, where did she go wrong with beetroot? One glimpse of it haemorrhaging its juice over the hard-boiled egg and iceberg lettuce in...

Drinking beetroot juice boosts stamina and could help people exercise for up to 16% longer, a UK study suggests. A University of Exeter team found nitrate contained in the vegetable leads to a reduction in oxygen uptake - making exercise less tiring. The small Journal of Applied Physiology study suggests the effect is greater than that which can be achieved by regular training. Beetroot juice has previously been shown to reduce blood pressure.
