The Claim
Sodium bicarbonate supplementation at a dose of 0.3 g/kg improves high-intensity exercise performance lasting between 30 seconds and 12 minutes in trained athletes, with average performance gains of 1.3% to 2.9% across cycling, running, swimming, and rowing, primarily by enhancing extracellular buffering capacity to delay muscle acidosis and sustain glycolytic energy production.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Sodium bicarbonate supplementation at 0.3 grams per kilogram of body weight increases high-intensity exercise performance by 1.3% to 2.9% in trained athletes during efforts lasting 30 seconds to 12 minutes, by increasing the body's ability to neutralize acid in the blood and maintain energy production from glycolysis.
See the scientific wording

When sodium bicarbonate is swallowed, it breaks down in the gut and enters the blood, raising the blood's ability to neutralize acid. This creates a stronger pull that draws acid out of muscle cells during intense exercise. As acid leaves the muscle, it stops interfering with the enzymes that make energy from sugar, allowing the muscle to keep producing power without slowing down.
What the research says
1 studyTaking a specific amount of baking soda before intense exercise helps athletes go faster for 30 seconds to 12 minutes by reducing muscle burn, and the study proves it works exactly as described.
