Built for thefourteenth sprint.

Lunges were faster, lactate lower mid-session (5.3 vs 6.5 mmol/L) and soreness 24 h later 26 vs 41 mm.

Pro footballers held their speed when fatigue hit: faster in sprints 14 and 15, and 1.9% faster over 30 m in the last.

Trained cyclists after 7 days: peak power 766 → 827 W, mean power 350 → 380 W.

Seven days of 20-minute hydrogen inhalation raised peak running velocity by up to 4.2% versus air.

After two weeks of hydrogen water, cyclists' peak power held steady in the late sprints. On placebo it fell about 12%.

839 vs 816 W in the first of six all-out sprints, with more oxygen extracted by the muscle.

A week of hydrogen water raised maximum and average 30-second rowing power and sped heart-rate recovery.

Hydrogen gas before four Wingate sprints improved mean power and fatigue index in the hardest, final sprint.

The runners with the most to gain cut up to 36 seconds off an uphill race.

National-level finswimmers after four days of loading. About a body length at that level.

At 3 W/kg: 4.0 vs 5.1 mmol/L. Lower perceived exertion and better breathing efficiency at 4 W/kg.

One dose raised average sprint power, cut the fatigue index and sped heart-rate-variability recovery.

A week of hydrogen water prevented the lactate rise seen on placebo during 30 minutes of hard cycling.

20 minutes of inhalation before hard cycling lowered perceived exertion at every stage and heart rate at 50–100% of max.

Hydrogen gas before cycling to exhaustion improved fatigue, exertion and pedalling cadence right at the end.

Two litres a day for 14 days raised blood pH and bicarbonate (28.3 → 30.5 mEq/L), a buffer against exercise acidity.

Elite finswimmers after two hard sessions in a day: CK 156 vs 190 U/L, less soreness and a higher jump.

One 30-minute hydrogen bath after damaging exercise kept CK and other muscle-damage markers at baseline.

Breathing hydrogen after strenuous exercise blunted a DNA-oxidation marker and the drop in jump height.

Hydrogen water stopped the day-by-day fall in blood antioxidant capacity across three days of repeated sprints.

A week of inhalation kept nitric oxide higher and lowered IL-6 and a DNA-damage marker after high-intensity training.

Post-exercise inhalation improved antioxidant capacity and lowered white-cell count and CRP in athletes.

78 vs 70 half-squat reps to failure and 9.6% more total power after eight days.

Handball and skeleton athletes gained torque after intensive tests, more muscle mass, less fat mass and lower CK.

Lower fatigue after exercise in 99 untrained people, and better endurance markers in 60 trained.

Two weeks of hydrogen water increased peak oxygen uptake and tended to raise peak load.

A single dose improved time to exhaustion at maximal aerobic speed in middle-distance runners.

Hydrogen tablets lowered heart rate and breathing rate through the first nine minutes of a graded test.

Triathletes cycling for an hour in the heat used less energy for the same work.

Hydrogen-rich cold water before a shuttle run in the heat improved aerobic speed, reps, lactate and mood.

Inhaling 1% hydrogen while cycling raised breath acetone, a marker of fat metabolism.

Three days of hydrogen-rich powder lowered breathing and raised resting bicarbonate during incremental cycling.

Fourteen days of inhalation, with better lung function too (FVC +0.19 L, FEV1 +0.11 L).

Fourteen days of hydrogen water improved fatigue, walking distance, chair stands and sleep quality.

Pro athletes recovered swelling, range of motion and balance as well with hydrogen foot baths as with ice.

Pro athletes with soft-tissue injuries regained range of motion faster with oral and topical hydrogen.

Over-50s starting strength training: less muscle damage, higher free testosterone, lower total and LDL cholesterol.

Older adults drinking hydrogen water also walked faster, balanced longer and gripped harder.

Six months of hydrogen water in over-70s improved chair-stand performance and telomere length.
