Dietary nitrate supplementation, administered in the form of nitrate-rich beetroot juice, has been shown to improve exercise performance and may have more pronounced effects on exercise that requires high-power and high-velocity muscle contraction such as weightlifting and body-mass resisted exercise (i.e, resistance exercise). However, limited data are available that have examined the potential performance enhancing effect of beetroot juice in resistance exercise. Moreover, there is no information on the dose of nitrate required for performance enhancing effects during resistance exercise which limits its widespread use to enhance performance. Therefore, the investigators will assess if supplementing the diet with nitrate-rich beetroot juice impacts resistance exercise performance (e.g., power, velocity), when compared to supplementing the diet with nitrate-depleted beetroot juice (i.e. placebo). The investigators will also investigate the dose-response effect of beetroot juice on resistance exercise performance by providing a low, moderate, and high nitrate dose of concentrated beetroot juice. The results of this study will improve understanding of whether beetroot juice influences resistance exercise performance and will provide insight on whether different doses of beetroot juice influence the efficacy of nitrate supplementation on resistance exercise performance. Together, these data will guide supplementation strategies for enhancing resistance exercise performance.
