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

Interestingly, when we calculated the watts that produced lactate concentrations equal to 2, 3, and 4 mmol using an exponential curve modeling procedure (r-value = 0.99 for all trial models), the watts required to generate these lactate values, as observed for lactate threshold, were greater during the nitrate supplementation trials compared to placebo for the 2 and 3 mmol points but did not reach statistical significance (3.3% (p = 0.14), 1.2% (p = 0.65), respectively).
