Beetroot juice may boost muscle power

Drinking concentrated beetroot juice increases muscle power in patients with heart failure, new research has found.

“It is a small study, but we see robust changes in muscle power about two hours after patients drink the beet juice,” said study senior author Linda Peterson, associate professor of medicine at Washington University School of Medicine in St. Louis.

The researchers believe that high nitrate content in beet juice could explain the improved muscle power in the study participants.

Earlier research had found that dietary nitrate improves muscle performance in many elite athletes. The nitrates in beet juice, spinach and other leafy green vegetables such as arugula and celery are processed by the body into nitric oxide, which is known to relax blood vessels and have other beneficial effects on metabolism.

The researchers observed the most substantial benefit when the muscles moved at the highest velocities. The increase in muscle performance was significant in quick, power-based actions, but researchers saw no improvements in performance during longer tests that measure muscle fatigue.

The researchers also pointed out that participants experienced no major side effects from the beet juice. The study appeared in the journal Circulation: Heart Failure.
