Figure 6. Sodium nitrate does not improve functional sympatholysis and does not increase exercise‐induced hyperaemia in healthy volunteers .

A, sodium nitrate supplementation failed to improve functional sympatholysis (exercise‐induced attenuation of reflex vasoconstriction, measured by NIR) in healthy male volunteers (n = 8). B, sodium nitrate supplementation did not affect resting skeletal muscle blood flow (measured by brachial artery Doppler ultrasound), nor did it affect exercise‐induced hyperaemia (n = 8). Data are expressed as the mean ± SE.
