Nitric oxide enhancement supplement containing beet nitrite and nitrate benefits high intensity cycle interval training.

Unlabelled: This study investigated the effects of a beet nitric oxide enhancing (NOE) supplement comprised of nitrite and nitrate on cycling performance indices in trained cyclists.

Methods: Subjects completed a lactate threshold test and a high-intensity interval (HIIT) protocol at 50% above functional threshold power with or without oral NOE supplement.

Results: NOE supplementation enhanced lactate threshold by 7.
