Eating beetroot before any workout helps. Baked beetle root in one of the study at St. Louis University Chicago gave runners a modest edge in speed during a 5K run when they were close to the finish line. With the beetroot, they were 41 seconds faster at the finish.

A study from the U.K also had shown that exercisers could work out longer if they drank beetroot juice. Other research has found that beetroot juice can help reduce blood pressure. Beetle root is rich in nitrates. Nitrates are converted into nitric oxide by the body. The nitric oxide dilates blood vessels. That results in improved oxygen delivery.

The study included whole vegetable rather than the juice. In the study of 11 men and women, average age 25, each ate 200 grams of beetroot (500 milligrams of nitrates). After the beetroot, exercisers had overall times that were 3% faster compared to their times after eating cranberry relish, and 5% faster during the last mile, she found.

In the study 200 grams of beetle nut was baked at 350 degrees for 90 minutes. The skin was peeled and rest added with a tablespoon of lemon juice, 1/8 teaspoon of cinnamon, and 1/8 teaspoon of nutmeg to make it more palatable. It was consumed about 45 minutes before they jogged or can be eaten two and a half hours before an event.
