The Claim

Ingestion of sodium bicarbonate at a dose of 0.3 g/kg has no effect on quadriceps muscle strength, electromyographic activity, perceived exertion, or perceived pain during high-intensity intermittent exercise in trained men.

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.

Description
1 study reviewed
In plain English

Taking sodium bicarbonate at 0.3 grams per kilogram of body weight does not change quadriceps strength, muscle electrical activity, how hard exercise feels, or how much pain is felt during high-intensity intermittent exercise in trained men.

See the scientific wording

Ingestion of sodium bicarbonate at a dose of 0.3 g/kg does not alter quadriceps muscle strength, electromyographic activity, perceived exertion, or perceived pain during high-intensity intermittent exercise in trained men, suggesting it provides no ergogenic benefit for these outcomes under these specific conditions.

Why this might work

The body's natural buffering system does not shift significantly when sodium bicarbonate is taken at this dose, so muscle acidity stays the same during intense exercise. This means nerve signals to the muscles, muscle contraction force, and how hard or painful the effort feels do not change.

    Scientists gave trained athletes a baking soda pill and a fake pill, then made them do intense leg exercises. Both pills had the same effect — no change in leg strength, muscle signals, or how hard or painful the workout felt. So, the baking soda didn’t help.
