Abstract

There is emerging evidence that hydrogen-rich water (H2-water) has beneficial effects on the physiological responses to exercise. However, few studies investigate its ergogenic potential. This randomized, controlled trial examined the effects of H2-water ingestion on physiological responses and exercise performance during incremental treadmill running. In a double-blind crossover design, fourteen endurance-trained male runners (34±4 years old; 63.1±7.2 kg; 1.72±0.05 m) were randomly assigned to ingest two doses of 290-mL H2-water or placebo on each occasion. The first bolus was given before six four-minute submaximal running bouts, and the second bolus was consumed before the maximal incremental running test. Expired gas, heart rate (HR), and ratings of perceived exertion (RPE) were recorded; blood samples were collected at the end of each submaximal stage and post maximal running test. Cardiorespiratory responses, RPE, and blood gas indices were not significantly different at each submaximal running intensity (range: 34-91%V̇O2max) between H2-water and placebo trials. No statistical difference was observed in running time to exhaustion (618±126 vs. 619±113 s), V̇O2max (56.9±4.4 vs. 57.1±4.7 mL∙kg-1∙min-1), maximal HR (184±7 vs. 184±7 beat∙min-1) and RPE (19±1 vs. 19±1) in the runners between the trials. The results suggest that the ingestion of 290 mL of H2-water before submaximal treadmill running, and an additional dose before the subsequent incremental running to exhaustion was not sufficiently ergogenic in endurance-trained athletes. Novelty bullets: • Acute ingestion of H2-water does not seem to be ergogenic for endurance performance. • A small dose of H2-water does not modulate buffering capacity during intense endurance exercise in athletes.
