Methods: Nine participants were recruited in this randomized, double-blind, placebo-controlled and crossover study. All participants were asked to ride on cycling ergometer at 70% maximal oxygen consumption (VO2 max) for 1 hour. During 4 hours recovery, participants were rehydrated with 1.5 fold weight equivalent to their body weight loss of placebo or high minerals water (hardness = 600). VO2 max, lower extremity muscle power, reaction time and heart rate variability (HRV) were measured one week before experiment, 4 and 24 hours after exercise challenge. Plasma cortisol, epinephrine and norepinephrine and body weight were measured one week before experiment, immediately after exercise, 4 and 24 hours after exercise. Results: Lower extremity muscle power and body weight were significantly lower in HMW trial compared to placebo group. Sympathetic activity was significantly lower at 24 hours after exercise challenge in HMW trial, yet the parasympathetic activity was significantly greater at 4 hours after exercise challenge in HMW trial compared to that of placebo trial. The plasma cortisol level was significantly lower at 24 hours after exercise in HMW group. However, the plasma epinephrine level was significantly lower at 4 hour after exercise challenge in HMW trial versus placebo trial. There were no significant differences in VO2 max, time to exhaustion during VO2 max test, reaction time, plasma norepinephrine level and creatine kinase activity between in two trials. Conclusions: Our results suggest that high minerals water supplementation have beneficial effects on rehydration and reduce physiologic stress after exercise challenge, thereby accelerating the physical recovery.
