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.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

In plain English

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.

Why this might work

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.

  1. Study: Effects of Combined Versus Isolated Beta-Alanine and Sodium Bicarbonate Supplementation on Physical Capacity in Highly Trained Female Basketball Players: A Randomized Controlled Trial.

    Taking 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.
