Effects of seawater ingestion on lactate response to exercise in runners
نویسندگان
چکیده
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 VO2 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.

Background. The acute ingestion of ketone body supplements can improve exercise responses such as oxygen consumption and blood lactate. Additionally, ketone body supplements show increases in circulating βhb concentration, matching those of someone in a state of nutritional ketosis. Studies testing ketone body supplements have reported different results in exercise response and varying gastroin...

متن کاملIngestion of oxygenated water enhances lactate clearance kinetics in trained runners
BACKGROUND Drinks with higher dissolved oxygen concentrations have in recent times gained popularity as a potential ergogenic aid, despite a lack of evidence regarding their efficacy. The aim of this study was to assess effects of ingestion of an oxygen supplement (OS) on exercise performance and post-exercise recovery in a group of trained runners. METHODS Trained male runners (n = 25, mean ...
