Effect of Beetroot Extract Supplementation on the Athletic Performance of Trained Rugby Athletes
In Brief
A clinical study evaluating beetroot juice - Placebo, 40 meters sprint, and 3 other interventions for Athletic Performance. Completed, enrolled 10 participants across 1 site.
Detailed 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.
Study Details
Timeline
Interventions
Participants receive the beetroot and placebo in the form of waffles to ensure the study is blinded, as the 6 mmol of nitrates used require a high concentration of beetroot, which is masked by the waffle ingredients and food coloring.
The participant performs a race at maximum speed with two attempts, times are taken at 10, 30 and 40 meters, to evaluate acceleration and speed, the attempt with the shortest times is the one taken for the research.
The participant runs a distance of 20, 40, and 60 meters, back and forth, 5 times at maximum speed. The variable to be measured is the total time taken to complete the test.
Each participant performs squats and bench press to evaluate lower-body and upper-body maximal strength, thus identifying their maximum strength taken per kilogram lifted.
At the end of the tests, each participant is asked to evaluate their perception of fatigue by giving a number between 1 and 10, with 1 being the lowest level of fatigue and 10 being the highest.
