Objective: The aim of the present study was to determine the effect of different doses of acute consumption of beetroot juice on anaerobic performance in trained individuals.Methodology: In a randomized (purposive and accessible) cross-over, double-blind, placebo-controlled experimental design, 9 subjects who were physically active for at least 150 minutes per week and for at least 6 months (age: 20.44±1.33 years, body mass index: 20.55±3.27 kg/m) volunteered to participate in the protocol during 3 weeks in a single session. 2 hours after consuming 70 mL or 140 mL of beetroot juice or 70 mL of placebo, participants completed the anaerobic power test based on running, Sargent jump test, Illinois agility test and the 36-meter speed test with a 10-minute rest interval. Findings: The results of data analysis showed that acute consumption of 70- and 140-ml doses of beet juice had no significant effect on anaerobic power, peak power, average power, minimum power, relative peak power, anaerobic capacity, fatigue index. In addition, acute consumption of 70 and 140 ml of beetroot juice did not have a significant effect on the speed, agility and explosive power of trained people.Conclusion: The results showed that the acute consumption of 70- and 140-ml doses of beet juice does not create any functional advantage for anaerobic power and its components, agility, speed and explosive power in trained people.
