The Claim

Oral and topical sodium bicarbonate have no significant effect on the recovery of muscle function or reduction of muscle soreness following exercise-induced muscle damage in soccer players, as measured by vertical jump height, maximal voluntary isometric contraction, and subjective soreness scores over a 72-hour period.

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.

Cause and effect
1 study reviewed
In plain English

Taking sodium bicarbonate by mouth or applying it to the skin does not improve muscle strength recovery or reduce muscle soreness after intense soccer play, based on measurements taken over three days.

See the scientific wording

Neither oral nor topical sodium bicarbonate accelerates recovery of muscle function or reduces muscle soreness after exercise-induced muscle damage in soccer players, as evidenced by no significant differences in vertical jump height, maximal voluntary isometric contraction, or subjective soreness scores compared to placebo over 72 hours.

Why this might work

When sodium bicarbonate is taken by mouth, it increases the level of bicarbonate in the blood. This allows hydrogen ions, which build up in muscles during intense activity, to move out of the muscle cells more easily. This keeps the inside of the muscle less acidic, which helps enzymes that make energy keep working longer. This does not change how fast muscles heal after damage or reduce how sore they feel.

  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

    The study found that using baking soda orally or on the skin didn’t help soccer players recover their muscle strength or feel less sore after hard exercise. It did help them run and move better in drills later, but that’s not what the claim is about.
