Taurine and alcohol has been popularly ingested through energy drinks. Reports from both compounds shows they are active on nervous system but little is known about the acute effect of these substances on the frontal cortex in an exercise approach. The aim of this study was to determine the effects of 0,6mldL of ethanol (ET), 6g of taurine (TA), and taurine with ethanol (TA+ET) intake on absolute alpha power (AAP) in the frontal region, before and after exercise. Nine participants were recruited, five women (22±3years) and four men (26±5years), for a counterbalanced experimental design. For each treatment, the tests were performed considering three moments: "baseline", "peak" and "post-exercise". In the placebo treatment (PL), the frontal areas showed AAP decrease at the post-exercise. However, in the TA, AAP decreased at peak and increased at post-exercise. In the ET treatment, AAP increased at the peak moment for the left frontal electrodes. In the TA+ET treatment, an AAP increase was observed at peak, and it continued after exercise ended. These substances were able to produce electrocortical activity changes in the frontal regions after a short duration and low intensity exercise. Left and right regions showed different AAP dynamics during peak and post-exercise moments when treatments were compared.
牛磺酸和酒精通常通过能量饮料摄入。关于这两种化合物的报告表明它们对神经系统有作用，但对于这些物质在运动状态下对额叶皮质的急性影响却知之甚少。本研究的目的是确定摄入0.6毫升/分升乙醇（ET）、6克牛磺酸（TA）以及牛磺酸与乙醇混合物（TA+ET）对运动前后额叶区域绝对阿尔法功率（AAP）的影响。招募了九名参与者，五名女性（22±3岁）和四名男性（26±5岁），采用平衡实验设计。对于每种处理，测试在三个时刻进行：“基线”、“峰值”和“运动后”。在安慰剂处理（PL）中，额叶区域在运动后AAP降低。然而，在TA处理中，AAP在峰值时降低，在运动后升高。在ET处理中，左额叶电极在峰值时刻AAP升高。在TA+ET处理中，峰值时观察到AAP升高，并且在运动结束后仍持续升高。这些物质在短时间、低强度运动后能够使额叶区域产生脑电活动变化。当比较不同处理时，左右区域在峰值和运动后时刻显示出不同的AAP动态变化。
