EFEITOS DO CONSUMO DA ERVA-MATE (Ilex paraguariensis) NOS INDICADORES DE DESEMPENHO FÍSICO: UMA REVISÃO DE ESCOPO

Abstract

Yerba mate (ilex paraguariensis) is a plant native to South America found in countries such as Brazil, Paraguay, Argentina and Uruguay. Recently, consumed in the form of tereré, it has become intangible heritage of humanity. In addition to its cultural value, its bioactive compounds indicate therapeutic and ergogenic potential. Studies conducted with yerba mate (YM) in healthy, physically active populations and athletes showed an increase in the mobilization of energy substrates, an improvement in the rate of muscle recovery and perception of effort. performance and post-exercise recovery. However, the literature lacks a review on yerba mate focusing on its use in conditions of physical exertion. Thus, this scope review aims to map and analyze the effects of yerba mate (ilex paraguariensis) consumption on physical performance indicators. The review was conducted in accordance with JBI guidelines; the research question and eligibility of the articles followed the PICO strategy. Furthermore, the PRISMA-ScR extension was used for scope review. Searches were performed on PubMed, SciELO, Lilacs, Virtual Health Library (VHL), Google Scholar and gray literature platforms in duplicate by two independent researchers. The following keywords were applied: Yerba Mate (Yerba Mate) / Ilex paraguariensis combined with physical exercise and performance. The search considered works published in English, Spanish and Portuguese. Initially, 101 studies were identified. By adopting the eligibility criteria and removing duplicates, 85 articles were excluded, remaining 16 studies. Most of the studies, 62.5% were carried out in Brazil; 75% of interventions used the cross-over approach; 50% was conducted with the male audience; 43,75% administered yerba mate through teas and 37,50% through capsules; 37,50% of the studies identified changes in the metabolism of energy substrates; 31,25% in protection against muscle injury and recovery of muscle strength; 25% on test time or test execution and 25% on subjective aspects such as PSE, fatigue, concentration and focus. Positive effects of YM on physical exertion parameters can be associated with its bioactive compounds, especially caffeine and chlorogenic acid. Most studies were carried out acutely, with a small sample size and without quantification of bioactive compounds in the plant and in vivo. More randomized clinical trials are needed to better understand the effects of YM in the field of physical exertion. The use of yerba mate as an ergogenic aid in the field of physical exercise can be considered as a possible promising nutritional strategy. Physically active individuals or athletes can benefit from improved performance and physical recovery.
