The Claim
A single dose of 0.2 to 0.5 grams of sodium bicarbonate per kilogram of body weight, consumed 60 to 180 minutes before exercise, improves high-intensity athletic performance.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking 0.2 to 0.5 grams of sodium bicarbonate per kilogram of body weight 60 to 180 minutes before exercise increases high-intensity athletic performance.
See the scientific wording
A single dose of 0.2 to 0.5 grams of sodium bicarbonate per kilogram of body weight, consumed 60 to 180 minutes before exercise, improves high-intensity athletic performance.
When someone takes sodium bicarbonate before intense exercise, it increases the level of bicarbonate in the blood. This allows the blood to soak up excess acid produced by muscles during hard effort. As a result, acid leaves the muscle cells faster, keeping the inside of the muscle less acidic. This lets the muscle contract harder and longer without slowing down from acid buildup.
What the research says
3 studiesTaking a specific amount of baking soda before intense exercise helped athletes produce more power during short, all-out sprints, without causing stomach or kidney problems. So yes, it worked.
This study found that cyclists who took a specific amount of baking soda (0.3 grams per kilogram of body weight) before riding could pedal longer before getting tired — about 76 seconds longer — compared to when they took nothing. This supports the idea that taking this dose before exercise helps athletes perform better.
Taking a specific amount of baking soda 1 to 3 hours before a tough workout can help athletes go faster or longer, especially in short, intense activities like sprinting or swimming. The science backs this up, but too much can cause stomach upset without extra benefit.
