Abstract

Energy drinks are nonalcoholic beverages whose main ingredients are sugar, taurine, and caffeine. The consumption of energy drinks is increasing worldwide, but only a few conflicting studies have investigated the vascular effects of energy drinks in young adults. The aim of this study was to evaluate microvascular reactivity before and after energy drinks consumption in young healthy male volunteers. This was a cross-sectional prospective study. Microvascular reactivity signals were evaluated in the skin of the forearm using laser speckle contrast imaging with acetylcholine (ACh) iontophoresis before and 90 and 180 min after the randomized consumption of one ED or the same volume of water (control), followed by a postocclusive reactive hyperemia (PORH) test. Thirty-two volunteers were evaluated (age: 25.4±4.3 years). Energy drink consumption prevented the rest-induced reduction in cutaneous vascular conductance over time that was observed in the control group. In the control group, there were significant reductions in microvascular vasodilation at 90 and 180 min compared to baseline (P=0.004), but this was not the case in the energy drink group (P=0.76). Our results demonstrated that the reduction in microvascular conductance associated with prolonged immobility can be prevented by the consumption of one energy drink, highlighting the vasodilator effects of this beverage in young individuals at rest. The between-study variability in terms of the brand of energy drinks and the ingested volume, as well as the method of vascular evaluation and the inclusion criteria, may explain the discrepancies among previous studies on the vascular effects of energy drinks.

饮用能量饮料对年轻男性志愿者休息时微血管反应性的急性影响:随机试验。
能量饮料是一种不含酒精的饮料,其主要成分是糖、牛磺酸和咖啡因。能量饮料的消费量在全球范围内不断增加,但只有少数相互矛盾的研究调查了能量饮料对年轻人血管的影响。本研究旨在评估年轻健康男性志愿者在饮用能量饮料前后的微血管反应性。这是一项横断面前瞻性研究。在随机饮用一种能量饮料或相同容量的水(对照组)之前、之后的 90 分钟和 180 分钟,使用激光斑点对比成像和乙酰胆碱(ACh)离子透入法对前臂皮肤的微血管反应信号进行评估,然后进行闭塞后反应性充血(PORH)测试。32 名志愿者接受了评估(年龄:25.4±4.3 岁)。饮用能量饮料可防止在对照组中观察到的由休息引起的皮肤血管传导性随时间推移而降低。在对照组中,与基线相比,90 分钟和 180 分钟时微血管舒张明显减少(P=0.004),但在能量饮料组中情况并非如此(P=0.76)。我们的研究结果表明,饮用一种能量饮料可防止因长时间静止不动而导致的微血管传导性降低,这凸显了这种饮料在年轻人静止状态下的血管扩张作用。研究之间在能量饮料的品牌、摄入量、血管评估方法和纳入标准等方面存在差异,这可能是以往关于能量饮料对血管影响的研究之间存在差异的原因。
