The Claim
Sodium bicarbonate supplementation at a dosage of 0.3 g/kg/day for 7 days increases peak power output during the first bout of repeated 30-second Wingate anaerobic tests in highly trained female basketball players by an average of 8.5% (from 761 to 821 W), with a large effect size (η² = 0.18), indicating enhanced extracellular buffering capacity improves short-duration, high-intensity performance without compromising subsequent efforts.
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 sodium bicarbonate at 0.3 grams per kilogram of body weight daily for seven days increases peak power output by 8.5% during the first 30-second all-out cycling test in highly trained female basketball players, without reducing performance in later tests.
See the scientific wording
Sodium bicarbonate supplementation (0.3 g/kg/day for 7 days) significantly increases peak power output during the first bout of repeated 30-second Wingate anaerobic tests in highly trained female basketball players, with an average improvement of 8.5% (from 761 to 821 W) and a large effect size (η² = 0.18), indicating enhanced extracellular buffering capacity improves short-duration, high-intensity performance without compromising subsequent efforts.
When sodium bicarbonate is taken, it increases the level of bicarbonate in the blood. This allows hydrogen ions, which build up in muscles during intense exercise, to move out of the muscle cells more easily. With fewer hydrogen ions inside the muscle, the muscle can keep contracting forcefully for longer, which lets a person generate more power at the start of a short, all-out effort.
What the research says
1 studyTaking sodium bicarbonate for a week helped female basketball players hit harder during their first all-out sprint, without making them weaker on later sprints. The supplement worked, and beta-alanine didn’t add anything extra.
