Published in Journal of the American Nutrition Association
Methodology
Systematic review and meta-analysis of randomised controlled trials of acute or short-term beetroot-based supplementation (316-985 mg/day inorganic nitrate, taken 2-3 h pre-exercise) on muscular endurance and strength in healthy men
Key Findings
Beetroot supplements produced a modest increase in repetitions to failure and time to exhaustion and attenuated the decline in muscular strength after fatiguing tasks.
Conclusions
Nitrate-rich beetroot supplementation gives modest muscular endurance benefits in healthy men.
Limitations
Healthy males only, small trials, acute/short-term protocols, heterogeneous nitrate doses.
Outcomes Measured
Beetroot-based supplements administration can generate a modest increase in the number of repetitions performed to failure or in exercise time to exhaustion
