EFEITO DO CONSUMO DE TERERÉ NA PERCEPÇÃO DE HUMOR DE ATLETAS

Abstract

Introduction: Tereré, a drink made from yerba mate, is a drink rich in ergogenic nutrients, such as caffeine, currently associated with disposition and vigor, and can act as an ally in sports. Therefore, it is important to evaluate how the acute consumption of tereré influences the mood of runners. Methodology: This is a randomized, double-blind, crossover study, approved by the Research Ethics Committee, which evaluated 19 adult street runners of both sexes (female: n= 9; age 32.8 ± 5.1 years, height 163.22 ± 4.47 cm, weight 56.8 ± 6.4 kg and fat percentage 20.6 ± 7% male: n =10; age 31.3 ± 8 years, height 173.55 ± 5.76 cm, weight 74.38 ± 10.23 kg, fat percentage 15.94 ± 4.24%), experienced in the sport and healthy. Participants consumed 50g of Tereré Experimental (TEx) or 50g of Tereré Placebo with decaffeinated yerba mate (TPl), administered with cold water (6 ml/kg) and after 60 minutes they performed the stable test (85% of comfortable running speed). followed by maximum exercise on a treadmill (lasting 20 to 27 minutes). Mood was assessed using the Brunel Mood Scale (BRUMS), which contains 24 moods distributed into six subscales: tension, depression, anger, vigor, fatigue and confusion. The scale has 5 alternatives for each mood, where zero corresponds to “not at all” and four corresponds to “extremely”. Each mood is scored from 0 to 4 points, while each subscale scores from 0 to 16 points. BRUMS was applied to participants at the end of the session. The athletes underwent the same assessments, alternating experimental conditions after a wash-out of 7 to 14 days. To compare the conditions, the non-parametric Mann-Whitney test was used, with a significance level of p<0.05. Results: From the subscales: Stress (TEx = 1.4 ± 2.3 vs TPl = 1.7 ± 2.2;p = 0.66), Depression (TEx = 0.1 ± 0.5 vs TPl = 0.3 ± 0.7;p = 0.43), Anger (TEx = 0.2 ± 0.7 vs TPl = 0.5 ± 0.8;p = 0.3), Vigor (TEx = 11.5 ± 2.6 vs TPl = 10.6 ± 3.5;p = 0.37), Fatigue (TEx = 2.2 ± 2.1 vs TPl = 2, 4 ± 2.0; p = 0.81) and Confusion (TEx = 0.4 ± 1.2 vs TPL = 0.5 ± 1.1; p = 0.76), it was observed that there was no difference between the two drinks (p <0.05). Conclusion: The results indicated that acute ingestion of tereré did not cause significant changes in the runners' mood.
