本研究调查了能量饮料与酒精的共同服用，以研究其对主观中毒和客观表现的影响。本研究旨在以平衡顺序、安慰剂对照、双盲设计，评估两种酒精剂量下酒精与安慰剂的客观和主观影响，无论是单独使用还是与能量饮料结合使用。两组 10 名健康志愿者参与了这项研究，平均年龄 (SD) 为 24 (6.5)。一组饮用含有 80 毫克咖啡因的能量饮料，另一组饮用安慰剂饮料，两组均服用两剂酒精（酒精浓度分别为 0.046% 和 0.087%）。测试包括呼吸酒精评估、客观表现测量（反应时间、单词记忆和斯特鲁普任务）和主观视觉模拟情绪量表。与不饮酒的情况相比，参与者在饮酒后表现出明显的反应时间和记忆力下降，并且在较高的酒精剂量后记忆力较差。与安慰剂饮料加酒精组合相比，能量饮料加酒精组合的斯特鲁普表现有所改善。与不饮酒相比，参与者在饮酒后感到明显的主观剂量相关损害。当与酒精混合时，呼吸酒精浓度和主观测量均未显示能量饮料和安慰剂能量饮料之间存在显着差异。主观影响反映了对酒精中毒的认识以及对增加酒精剂量的敏感性。在酒精存在的情况下，能量饮料组和安慰剂组之间的主观测量没有总体显着的组间差异，并且没有证据表明能量饮料掩盖了任一剂量的酒精的主观影响。
This study investigated the coadministration of an energy drink with alcohol to study the effects on subjective intoxication and objective performance. This study aims to evaluate the objective and subjective effects of alcohol versus placebo at two alcohol doses, alone and in combination with an energy drink, in a balanced order, placebo-controlled, double-blind design. Two groups of ten healthy volunteers, mean (SD) age of 24 (6.5), participated in the study. One group consumed energy drink containing 80 mg of caffeine and the other consumed a placebo drink, with both receiving two alcohol doses (0.046 and 0.087% breathalyser alcohol concentration). Tests included breath alcohol assessment, objective measures of performance (reaction time, word memory and Stroop task) and subjective visual analogue mood scales. Participants showed significantly impaired reaction time and memory after alcohol compared to the no alcohol condition and had poorer memory after the higher alcohol dose. Stroop performance was improved with the energy drink plus alcohol combination compared to the placebo drink plus alcohol combination. Participants felt significant subjective dose-related impairment after alcohol compared to no alcohol. Neither breath alcohol concentration nor the subjective measures showed a significant difference between the energy drink and the placebo energy drink when combined with alcohol. Subjective effects reflected awareness of alcohol intoxication and sensitivity to increasing alcohol dose. There were no overall significant group differences for subjective measures between energy drink and placebo groups in the presence of alcohol and no evidence that the energy drink masked the subjective effects of alcohol at either dose.
