The aim of this study was to examine the effect of microfiltered and sterilized seawater ingestion on running performance in a hot environment. This cross-over, double-blind randomized trial included 12 experienced male runners. The subjects randomly consumed seawater (SW) or pure water (placebo) in an equivalent amount of 50 ml five minutes prior to running at 40% of their VO max for 95.0 ± 18.5 min, at 30°C, until they lost 3% of body weight. Every 20 minutes, a measurement of their body weight was taken and a blood lactate analysis was performed. The concentration of lactate was significantly lower after the running exercise in the SW condition compared to placebo. The results of this study provide evidence supporting the ergogenic effects of microfiltered and sterilized seawater ingestion on running performance and lactate production.
本研究的目的是考察摄入经过微滤和消毒的海水对在炎热环境中跑步表现的影响。这项交叉、双盲随机试验纳入了12名经验丰富的男性跑步者。受试者在以其最大摄氧量的40%在30°C下跑步95.0±18.5分钟前五分钟,随机饮用等量50毫升的海水(SW)或纯水(安慰剂),直至体重减轻3%。每隔20分钟测量一次体重,并进行血乳酸分析。与安慰剂相比,在SW条件下跑步运动后乳酸浓度显著更低。本研究结果提供了证据,支持摄入经过微滤和消毒的海水对跑步表现和乳酸生成具有促力作用。
