The Claim

Topical sodium bicarbonate (0.9036 g/kg body mass via PR Lotion) does not improve functional recovery or soccer-specific performance after exercise-induced muscle damage in soccer players, despite elevating blood pH post-exercise, indicating that transdermal delivery is insufficient to enhance performance under fatigue.

Cause and effect
1 study reviewed
In plain English

Applying sodium bicarbonate through a lotion at a dose of 0.9036 grams per kilogram of body weight does not improve recovery or soccer performance after muscle damage from exercise, even though it raises blood pH, because the skin delivery method does not produce enough systemic effect to influence performance.

See the scientific wording

Topical sodium bicarbonate (0.9036 g/kg body mass via PR Lotion) does not improve functional recovery or soccer-specific performance after exercise-induced muscle damage in soccer players, despite elevating blood pH post-exercise, suggesting transdermal delivery is insufficient to enhance performance under fatigue.

Why this might work

When sodium bicarbonate is applied to the skin, it enters the bloodstream and raises blood pH, but it does not reach deep muscle tissue in enough quantity to neutralize the acid that builds up during intense exercise. Without this acid neutralization inside the muscle, enzymes that produce energy keep getting slowed down, so the muscle tires faster and recovery doesn't improve.

  1. Study: Effect of Oral and Topical Sodium Bicarbonate on Functional Recovery and Soccer-Specific Performance After Exercise-Induced Muscle Damage: A Randomized, Double-Blind, Placebo-Controlled Study

    Putting sodium bicarbonate lotion on the skin after a tough soccer game didn’t help players run faster or recover better, even though it slightly changed their blood chemistry. Only swallowing it helped a little.
