Psychological effects of beetroot juice supplementation in high performance field hockey players

Abstract

The main purpose of the study was to analyze the psychological effects of beetroot juice supplementation in high-performance field hockey players. The hypothesis raised in the research was that beetroot juice supplementation has an impact on mood, more specifically increasing Tension and Vigor. On the other hand, differences in State Anxiety and Satisfaction are not expected.

The sample used for this study consisted of nine participants between the 18 and 32 years old. This was a double-blind, randomized study. The sample participated in two sessions where they consumed supplement or placebo. Before starting the practice session, the subjects completed the POMS and CSAI-2R questionnaires. At the end of the practice session players completed the Satisfaction Scale. The results obtained indicate that there were no significant differences in any dimension of the POMS questionnaire except in the Confusion dimension. Also, there were no significant differences in the Anxiety and Satisfaction scales.
