This study investigated the effect of deep sea water electrolyte drink supplement on blood electrolyte concentration and exercise performance during acute exercise in hot environment. This study has selected 11 healthy males (23±1.8 years; 65.9±6.92 kg; 172.5±6.9 cm) as the subjects. Exercise protocol was conducted on a treadmill (30°C±2 / all-out) by using Bruce protocol. Blood sample were obtained at baseline, immediately and 30 min post-exercise. The source variables of blood electrolyte elements were Na+, Cl-, K+ and blood lactate, ADH. The source variables of exercise performance were total exercise time and VO2max. The results of this study were as follows; First, the blood electrolyte elements were increased by deep-sea water compared with water intake, but not significantly. Second, blood lactate and ADH were increased deep-sea water compared with water intake, but not significantly. On the other hand, both of exercise time and VO2max were significantly increased in deep-sea water intake (p<.05). Deep-sea water electrolyte supplement intake didn't have a significant difference on the change in blood electrolyte concentration, it showed higher level of electrolyte concentration compared with water intake. Therefore, further study should be conducted under the condition of long-time intake. Meanwhile, deep-sea water electrolyte supplement intake is considered to enhance exercise time and VO2max. Thus it can be said to have a positive effect up on exercise performance in hot environment. |
