Title: The effect of beet juice-based foods on the performance of athletes in cyclic sports


Modern data from the scientific literature indicate that nitrate, when added to food, can serve as a precursor of nitric oxide (NO). AIMS: To evaluate the effect of consumption of beet juice, as a source of nitrates, on the performance of biathletes-sprinters. MATERIALS AND METHODS: Forty male biathletes aged from 18 to 22 years took part in the study. The athletes were divided into an experimental group and a control group. The experimental group was given a preparation containing beet juice of a special variety twice daily after each training session, and the athletes of the control group did not consume anything after training sessions. Before the experiment and after 20 days of intervention, load testing before work refusal was carried out, as well as biochemical and general blood analysis. RESULTS: In the athletes of the experimental group, who were consuming beet juice, there was a decrease in oxygen uptake per kilogram of body weight and an increase in heart rate at the moment of anaerobic threshold, as well as an increase in load time, which indicates an increase in endurance during anaerobic exercise.
