Background: Beetroot juice is a sport supplement with a high level of evidence on the
physical performance enhancement. However, in swimming, there is no clear data about the
effects of beetroot juice on performance. Objective: To investigate whether an acute intake of
beetroot juice (BJ) improves the performance of competitive swimmers in a repeated
maximum swimming effort. Method: Thirteen national-level swimmers (six females and
seven males), participated in this randomized, double-blind crossover study. In two different …
