Drinking alkaline water after intense anaerobic exercise may enhance both cognitive and physical performance. This study aimed to investigate the effect of high mineral alkaline water consumed over three consecutive days on reaction time after anaerobic exercise in twelve healthy young males (aged 21.1 ± 1.3 years) with a valid sports medical examination. Participants were excluded when they took any medications or performance-enhancing supplements for the period of at least four weeks before the study commenced. Participants were randomly divided into two groups in this double-blind, placebo-controlled crossover pilot study. They ingested either alkaline water (AW) or regular table water ( RTW) for three consecutive days before anaerobic exercise. The anaerobic exercise consisted of two 2-min high-intensity step-tests with a passive rest interval of 3 minutes between the two bouts of exercise. Performance in the step-test (W), reaction time for visual and auditory signals, the rate of perceived exertion (RPE), urine specific gravity, and lactate concentration were analysed. No effect of AW was found on reaction time and the other variables except anaerobic performance. An-aerobic performance was significantly higher after ingestion of AW in both step-tests (p < 0.05). The ingestion of AW for three consecutive days before anaerobic exercise seems to positively affect anaerobic performance.
在高强度无氧运动后饮用碱性水可能会提高认知能力和身体表现。本研究旨在调查连续三天饮用高矿物质碱性水对12名经过有效运动医学检查的健康年轻男性（年龄21.1±1.3岁）无氧运动后反应时间的影响。在研究开始前至少四周内服用任何药物或性能增强补充剂的参与者被排除在外。在这项双盲、安慰剂对照的交叉试点研究中，参与者被随机分为两组。他们在无氧运动前连续三天饮用碱性水（AW）或普通自来水（RTW）。无氧运动包括两次2分钟的高强度台阶测试，两次运动之间有3分钟的被动休息间隔。分析了台阶测试中的表现（瓦特）、视觉和听觉信号的反应时间、主观用力程度（RPE）、尿比重和乳酸浓度。除无氧运动表现外，未发现碱性水对反应时间和其他变量有影响。在两次台阶测试中，摄入碱性水后无氧运动表现均显著更高（p<0.05）。无氧运动前连续三天饮用碱性水似乎对无氧运动表现有积极影响。
