Exclusion criteria

Exclusion criteria: Just before examination, if body temperature or blood pressure exceeds 37 degree or 141 mmHg, we will exclude him from the subjects.

Design outcomes

Primary

Measure	Time frame
After drinking 500 mL placebo or hydrogen water, maximum oxygen consumption and a conscious fatigue degree of volunteers are measured by bicycle-exercise with an ergometer. The maximum oxygen consumption is examined by gradually raising the load of the pedal, and monitoring a change of the heart beat pulse and normalized by age, body weight. The conscious fatigue degree is reported according to the Borg index and a visual analog scale (VAS).	—
