Resumo
Observou-se recentemente uma rápida popularização do consumo de bebidas energéticas
(BE) a base de cafeína e taurina, que segundo seus produtores, foram criadas para incrementar a
resistência física, proporcionar reações mais rápidas e melhorar a concentração e estado de alerta
mental, promover sensação de bem estar, estimular o metabolismo e ajudar a eliminar substâncias
nocivas ao organismo. Há poucos estudos investigando os efeitos fisiológicos do exercício físico
após a ingestão de BE. Relatos de morte após consumo de BE e álcool levantam polêmicas em
relação às informações direcionadas aos consumidores, incluindo suas contra-indicações, gerando
controvérsias a respeito de seus reais efeitos. Por outro lado, alguns estudos sugerem melhora do
desempenho psicomotor e do estado de humor após ingestão de BE e seus componentes. Objetivo:
Avaliar a frequência de uso de BE entre praticantes de atividades físicas; verificar a freqüência de
possíveis alterações comportamentais, fisiológicas e psicológicas relatadas pelos usuários; e
investigar a frequência de uso de outros tipos de BE e/ou estimulantes por esta população, através do
uso de um questionário padrão. Resultados: A maior parte da amostra relatou fazer uso de BE tanto
isoladamente (94,5%) como em combinação com bebidas alcoólicas (70,9%). Após a ingestão de
bebida energética pura, 60% dos entrevistados relataram não sentir nenhuma alteração, no entanto
23,6% relataram aumento do vigor físico e 2,7% insônia. Quando ingeridas em combinação com
álcool, 12,7% dos entrevistados relataram insônia, 25,4% aumento da alegria, 41% aumento da
euforia, 14,5% desinibição e 8,1% aumento do vigor físico. Entre os compostos associados à prática
de atividades física, as BE apresentam 19% de ocasiões de uso, entre outros compostos destacam-se
o uso de isotônicos (28%), suplementos alimentares à base de aminoácidos e proteínas (16,3%),
suplementos alimentares à base de carboidratos (18%) e creatina (6,3%). Discussão: Os resultados do
presente estudo corroboram a alta prevalência de uso combinado de BE com bebidas alcoólicas,
indicando que as BE vêm sendo utilizadas para potencializar os efeitos estimulantes e reduzir os
efeitos depressores do álcool. Apesar de o presente estudo ter sido realizado em locais associados à
prática de atividades físicas, o número de usuários de bebidas energéticas associadas a está prática
foi relativamente baixo (19%), sendo sua maior incidência de uso em festas (69%) e casas noturnas
(44,5%), percebendo-se sua alta prevalência do uso com objetivo de manter-se acordado (33,6%).
Em relação ao uso de outros compostos associados à prática de atividades físicas, os principais
objetivos observados foram: aumento de massa muscular (28%), obter mais energia (27,2%) e
reposição hídrica (15,4%). Considerações finais: Outros estudos precisam ser realizados abordando o
uso de BE e atividade física, padronizando o tipo, intensidade, protocolo e duração do exercício,
analisando variáveis metabólicas, hemodinâmicas e de capacidades físicas para que dados mais
confiáveis sejam produzidos.
Was observed recently a fast popularization of energy drinks (ED) containing caffeine and taurine, what according to its producers, these substances increase performance, provide fast reactions and improve concentration and alertness, promote sense of well being, stimulating metabolism and help eliminate harmful substances to the body. There are few studies investigating the physiological effects of exercise after ingestion of ED. Reports of death after consumption of alcohol and ED raise controversy regarding the information directed to consumers, including the contraindications, generating controversy about its real effects. On the other hand, some studies suggest improvement of psychomotor performance and mood after ingestion of BE and its components. Objective: Investigate the frequency of use of ED between practitioners of physical activities and verify the frequency of possible behavioral changes, physiological and psychological reported by users, and investigate the frequency of use the other types of ED and / or stimulants in this population through the use of a pattern questionnaire. Results: The majority part of the sample reported they used ED alone (94.5%) or ED in combination with alcohol (70.9%). After ingestion of ED pure, 60% of interviewed reported not sense any change, however 23.6% reported increased physical vigor and 2.7% insomnia. When taken in combination with alcohol, 12.7% of interviewed reported insomnia, 25.4% increased happiness, 41% increase in euphoria, disinhibition 14.5% and 8.1% increase in physical vigor. Among the compounds associated with the practice of physical activities, the ED have 19% of occasions of use, between other compounds include the use of isotonic beverages (28%), food supplements based on amino acids and proteins (16.3%) food supplements based on carbohydrates (18%) and creatine (6.3%). Discussion: The results of this study corroborate the high prevalence of use of ED combined with alcohol, indicating that ED have been used to enhance the stimulating effects and reduce the depressant effects of alcohol. Although the present study been was realized at places associated with physical activity, the number of users of energy drinks is associated with practice was relatively low (19%), being its more incidence of use at parties (69%) and night clubs (45%), perceiving the highest prevalence using with in goal to stay awake (33.6%). Regarding the use of other compounds associated with physical activity, the main objectives were observed: increase in muscle mass (28%), more energy (27.2%) and hydration (15.4%). Conclusion: More studies are needed about the use of ED and physical activity, standardizing the type, intensity, protocol and duration of exercise, analyzing variables metabolic, hemodynamic and physical capabilities to results more reliable data are produced
