PURPOSE: Exercise under high temperature conditions cause dehydration that causes loss lot of minerals, which simultaneously influence the individual performance. The present study was purposed to investigate the impact of deep ocean-based desalted mineral water (DOMW) on athlete's performance after performing the dehydration exercise regimen. METHODS: In this double-blind cross over study, we recruited twelve healthy young men. All the subjects were performed prolonged treadmill running at 40% VO sub(2)max under 30 super(0)C leading to 3% body weight loss. Then subjects were orally supplemented with deep ocean-based desalted mineral water (DOMW, N=6) or pure water (placebo, N=6) in the volume equivalent to 1.5 fold of their body weight loss, and consumed in 150-min. One-week after washout crossover trial was performed. Leg explosive power (instantaneous force change measured by force plate), maximal aerobic capacity (VO sub(2)max) and changes in heart rate variability (HRV) were measured at 4-h and 24-h during post-exercise recovery. RESULTS: We found that exercise challenge caused a significant drop in explosive power at 4-h of recovery. However, DOMW supplementation showed higher recovery rate in explosive power above the placebo trail. Furthermore, only in DOMW trail, VO sub(2)max was significantly improved with concurrent increased heart rate variability (HRV) during recovery. CONCLUSIONS: The result of the present study provides some supportive evidences that deep ocean-based desalted mineral water can accelerate recovery in physical performance after prolonged exercise challenge under high temperature condition.
