H2HUBB TAKEAWAY
Hydrogen-rich water did not significantly affect time to exhaustion, post-exercise blood lactate, maximal heart rate, or oxygen uptake.
What the Researchers Studied
This study investigated the effects of acute, pre-exercise, hydrogen rich water (HRW) ingestion on running time to exhaustion at maximal aerobic speed in trained track and field runners.
How Molecular Hydrogen Was Used
Molecular hydrogen was administered as hydrogen-rich water.
What the Researchers Found
When running to exhaustion at maximal aerobic speed, compared with placebo, HRW had no significant effects on the following variables: time to exhaustion (217 ± 49 and 227 ± 53 s, p = 0.20), after exercise blood lactate concentration (9.9 ± 2.2 and 10.1 ± 2.0 mmol⋅L-1, p = 0.42), maximal heart rate (186 ± 9 and 186 ± 9 beats⋅min-1, p = 0.80), and oxygen uptake (53.1 ± 4.5 and 52.2 ± 4.7 ml⋅kg-1⋅min-1, p = 0.33).
H₂ Mechanisms / Biological Findings
The source material reviewed did not establish a specific molecular hydrogen mechanism for the reported findings.
Authors’ Conclusion
The authors concluded that pre-exercise administration of 1260 ml of HRW showed no ergogenic effect on running performance to exhaustion at maximal aerobic speed in trained track and field runners.
