Researchers at the University of Exeter, UK, found that beet juice can be a great ally for people who want to improve performance in muscle mass training.

The drink significantly increases muscle strength, allowing bodybuilders to lift heavier loads and perform higher numbers of repetitions.

In a study published Jan. 6 in the journal Physiological Minutes, scientists explain that certain vegetables, such as beets, are rich in nitrates. The substance helps to dilate the blood vessels, increasing the amount of oxygen that reaches the muscles, and is therefore associated with the gain of physical resistance.

Pre workout

The research had the participation of ten healthy men aged between 20 and 30 years. They ate a diet low in nitrate foods for the three days prior to the start of the experiment.

Then they were divided into two groups. Five of them had a pre-workout drink with the amount of nitrate equivalent to that found in a glass of beetroot juice. The others consumed a drink without nitrate. None of them knew what they were consuming.

Three hours later, the participants did a series of physical exercises with 60 contractions of the quadriceps muscles – located in front of the thigh – while the dominant leg was attached to the lever of a machine.

With the help of electrical pulse equipment, the researchers were able to measure the muscle force applied during the experiment. Those who took the mixture with nitrate had a torque – moment of force – 7% higher compared to the others.

Leg muscle biopsies were collected at three moments: after drinking the drink and before and after the exercises. Participants who consumed the nitrate drink had higher levels of the substance in their muscles.

“This study provides the best evidence to date on the mechanisms behind why nitrate improves human muscle performance,” wrote physiologist Andy Jones of the University of Exeter.
