Effect of Antibacterial Mouthwash on Muscle Function in Healthy Young Men and Women

The purpose of this study is to determine the effects of antibacterial mouthwash on muscle speed and power in healthy young men and women. We have previously demonstrated that drinking beetroot juice, a source of dietary nitrate and therefore nitric oxide, increases muscle function in this population. Antibacterial mouthwash has been shown to interfere with the conversion of dietary nitrate to nitric oxide. We therefore hypothesize that it will diminish nitric oxide bioavailability and inhibit muscle contractility.
