The Claim
Higher body mass is associated with greater performance benefit from sodium bicarbonate supplementation in endurance runners.
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.
Endurance runners with higher body mass show greater performance improvements when taking sodium bicarbonate compared to runners with lower body mass.
See the scientific wording
Higher body mass is associated with greater performance benefit from sodium bicarbonate in endurance runners, suggesting that larger athletes may derive more ergogenic advantage from this supplement.
Larger athletes produce more acid during intense running because they have more muscle mass generating energy without oxygen. Sodium bicarbonate in the blood soaks up this acid, keeping muscles from getting too acidic. This lets muscles keep contracting strongly for longer, so bigger athletes gain more benefit from the supplement.
What the research says
1 studyThe study found that heavier runners tended to get a bigger performance boost from baking soda than lighter ones, which supports the idea that bigger athletes benefit more because they produce more acid during hard exercise.
