Yes —
beetroot nitrate can improve endurance performance, particularly in
aerobic and submaximal exercise.
Dietary nitrate from beetroot increases
nitric oxide (NO) availability, which improves blood flow, oxygen efficiency and muscle contraction economy.
Research shows the strongest benefits in:
- endurance sports (running, cycling, rowing),
- longer efforts at moderate intensity,
- recreational and sub-elite athletes.
Performance gains are typically
small but consistent (≈1–4%), which is
meaningful in endurance contexts, where marginal improvements matter.
