Summary
Beetroot is a source of nitrates, which have demonstrated various positive effects in sports, with little evidence in intermittent sports such as ball sports (including rugby). Therefore, the study's hypothesis is that it may also have an effect in these sports. For this purpose, a beetroot extract was used, a product approved by the Colombian institution in charge of product approval and registration in Colombia, the National Institute for Food and Drug Surveillance (INVIMA). This was done to determine whether it has any effect on various physical abilities required for rugby, such as speed, acceleration, strength, and fatigue perception.
