饮用混合能量饮料（AmED）的酒精饮料已成为年轻人中流行且有争议的做法。不清醒驾驶和伤害发生率的增加与 AmED 的消费有关。本研究的目的是检验与单独饮酒相比，服用 AmED 是否会改变认知处理和中毒的主观测量。 18 名参与者（9 名男性和 9 名女性）参加了 4 次测试，他们随机接受 4 种剂量中的一种（0.65 克/千克酒精、3.57 毫升/千克能量饮料、AmED 或安慰剂饮料）。心理不应期（PRP）任务的表现用于测量双任务信息处理，普渡钉板任务的表现用于测量剂量给药后的简单和复杂的运动协调性。此外，还记录了刺激、镇静、损伤和中毒水平的各种主观测量结果。结果表明，酒精会减慢双任务信息处理速度，并损害简单和复杂的运动协调能力。能量饮料与酒精的共同服用并没有改变酒精引起的这些客观指标的损害。对于主观影响，酒精会增加表明醉酒感觉的各种评级。更重要的是，与单独饮酒相比，同时服用能量饮料和酒精可以减少精神疲劳感并增强刺激感。总之，AmED 可能会导致饮酒者出现高风险情况。行为障碍与疲劳减轻和刺激增强的结合可能会导致 AmED 消费者错误地认为自己比实际情况更能发挥作用。
The consumption of alcohol mixed with energy drinks (AmED) has become a popular and controversial practice among young people. Increased rates of impaired driving and injuries have been associated with AmED consumption. The purpose of this study was to examine if the consumption of AmED alters cognitive processing and subjective measures of intoxication compared with the consumption of alcohol alone. Eighteen participants (9 men and 9 women) attended 4 test sessions where they received one of 4 doses in random order (0.65 g/kg alcohol, 3.57 ml/kg energy drink, AmED, or a placebo beverage). Performance on a psychological refractory period (PRP) task was used to measure dual-task information processing and performance on the Purdue pegboard task was used to measure simple and complex motor coordination following dose administration. In addition, various subjective measures of stimulation, sedation, impairment, and level of intoxication were recorded. The results indicated that alcohol slowed dual-task information processing and impaired simple and complex motor coordination. The co-administration of the energy drink with alcohol did not alter the alcohol-induced impairment on these objective measures. For subjective effects, alcohol increases various ratings indicative of feelings of intoxication. More importantly, co-administration of the energy drink with alcohol reduced perceptions of mental fatigue and enhanced feelings of stimulation compared to alcohol alone. In conclusion, AmED may contribute to a high-risk scenario for a drinker. The mix of behavioral impairment with reduced fatigue and enhanced stimulation may lead AmED consumers to erroneously perceive themselves better able to function than is actually the case.
