Influence of beetroot juice supplementation on intermittent exercise performance
Thompson C, Wylie LJ
Published in European Journal of Applied Physiology
Methodology
Randomized double-blind crossover trial of nitrate-rich beetroot juice on intermittent high-intensity exercise performance and blood lactate.
Key Findings
Beetroot juice improved intermittent sprint performance with lower blood lactate at matched workloads in some measures, but not all endpoints reached significance.
Conclusions
Dietary nitrate can shift the lactate response to submaximal work, with inconsistent performance effects.
Limitations
Small trained sample; acute supplementation only.
Outcomes Measured
Beetroot juice improved intermittent sprint performance with lower blood lactate at matched workloads, though not all endpoints reached significance
