Dietary Nitrate Increases VO2peak and Performance but Does Not Alter Ventilation or Efficiency in Patients With Heart Failure With Reduced Ejection Fraction

Acute dietary NO3− intake increases VO2peak and performance in patients with HFrEF. These data, in conjunction with our recent data demonstrating that dietary NO3− also improves muscle contractile function, suggest that dietary NO3− supplementation may be a valuable means of enhancing exercise capacity in this population.
