Increases Stamina
If the muscles use fuel more efficiently, it can increase stamina, and several studies on beets prove this. For example, in one study, men aged 19 to 38 cycled using exercise bikes. During the study, the participants drank about half a liter of beet juice every day. They cycled 16 percent longer than their usual performance and di not suffer from exhaustion.
In another study, the researchers used runners who consumed beets before their run. The test showed that they gained an edge over other runners, achieving an average of 41 seconds in a 5k run, which was a significant advantage. The increase in stamina and performance is due the beets’ ability to increase the blood’s oxygen-carrying capacity. At the same time, it minimizes the amount of oxygen the muscles need for optimum performance.
These tests and other studies on beets show that they can effectively lower the oxygen cost of exercise by efficiently increasing the blood flow to the limbs. There are already results of the beets improving the exercise performance of people who suffer from the narrowing of the blood vessels that carry blood from the heart and lower extremities (peripheral artery disease).
