Summary

The main aim of this study is to determine and compare the optimal time to achieve peak concentration of blood plasma nitrite after ingestion of beetroot juice (BR) and isotonic beetroot juice (ISO-CB), respectively. Optimal timing of drink consumption in relation to exercise can then be prescribed in relation to nitrite appearance in the blood. A randomised controlled trial with participants completing two conditions: (i) BR and (ii) ISO-CB. On each condition participants will consume During each trial, participants will ingest 2 x 285ml of beverage 3 hours prior to performing two jump tests follow by a Wingate test. Salivary NO content will be measured at the start of the morning, 1 hour, 2 hours, 3 hours after consumption of beverage and at the end of the exercise.
