The Claim
Pre-exercise sodium bicarbonate ingestion increases sodium/hydrogen exchanger 1 (NHE1) protein content by 58.7% in the vastus lateralis muscle of healthy young men 24 hours after sprint-interval exercise, compared to placebo.
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.
In healthy young men, taking sodium bicarbonate before sprint-interval exercise results in a 58.7% higher level of NHE1 protein in the thigh muscle 24 hours later, compared to taking a placebo.
See the scientific wording
Pre-exercise sodium bicarbonate ingestion increases sodium/hydrogen exchanger 1 (NHE1) protein content by 58.7% in the vastus lateralis muscle of healthy young men 24 hours after sprint-interval exercise, an effect not observed with placebo, suggesting alkalosis selectively enhances NHE1 adaptation.
Taking sodium bicarbonate before intense exercise makes the blood less acidic, which reduces damage to muscle proteins caused by stress. This allows the muscle to build more of a protein that removes acid, and this increase happens only after exercise and only when the blood was less acidic during recovery.
What the research says
1 studyTaking baking soda before intense biking made a muscle protein that removes acid increase by almost 60% the next day—but only in people who took baking soda, not those who took a fake pill. So yes, it works as claimed.
