Male SD rats were randomly divided intofour groups: control (C), H2 water (H2), control-exercise (C-Ex), H2water-exercise (H2-Ex). Each group was given mineral water or H2water ad libitum for 2 weeks. Then theexercise groups (C-Ex and H2-Ex) were performed treadmill running at18 m/min (6° graded) for 60 min. Blood, skeletal muscle and liver sampleswere analysed for tissue glycogen contents and blood energy substrats (i.e., glucose,free fatty acid, lactate). Two-way ANOVA revealed that H2 intake decreasedfree fatty acid (p < 0.001) andincreased lactate concentration (p =0.004). In comparison of the change from the rest in C-Ex and H2-Exgroups, blood free fatty acid and liver glycogen content were significantly lowerin H2-Ex group than in the C-Ex group (p =0.001, p = 0.035, respectively). On the other hand, bloodlactate concentration was significantly higher in the H2-Ex group than inthe C-Ex group. These results suggest that chronic H2 water intake mayincrease liver glycogen utilization without changing muscle glycogenutilization during exercise.
