Abstract

Background Nitrate supplementation is thought to improve performance in endurance sports. Objective To meta-analyze studies evaluating the effect of nitrate supplementation on endurance sports performance among adults. Data sources We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Web of Science and CINAHL without language restrictions. Methods We included studies that: 1) compared nitrate supplementation with placebo; 2) enrolled adults engaging in an endurance-based activity; and 3) reported a performance measure or surrogate physiologic outcome. We evaluated risk of bias using the Cochrane Collaboration tool and pooled data with a random-effects model. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to evaluate confidence in estimates. Results We included 73 studies (n = 1061). Nitrate supplementation improved power output (MD 4.6 watts, P
