The Claim

Oral sodium bicarbonate (0.3 g/kg body mass) administered 2 hours before a soccer-specific performance test 72 hours after exercise-induced muscle damage attenuates the decline in agility and endurance performance in male and female soccer players, with large effect sizes (g = 1.69 for Illinois Agility Test and g = 1.61 for Yo-Yo Intermittent Recovery Test Level 2), due to elevated blood bicarbonate and pH that enhance hydrogen ion buffering during high-intensity exercise.

Cause and effect
1 study reviewed
In plain English

Taking sodium bicarbonate at a dose of 0.3 grams per kilogram of body weight two hours before a soccer performance test, 72 hours after muscle damage, reduces the loss of agility and endurance in male and female soccer players. This effect is associated with increased blood bicarbonate and pH levels, which improve the body's ability to neutralize hydrogen ions during high-intensity exercise.

See the scientific wording

Oral sodium bicarbonate (0.3 g/kg body mass) administered 2 hours before a soccer-specific performance test 72 hours after exercise-induced muscle damage attenuates the decline in agility and endurance performance in male and female soccer players, with large effect sizes (g = 1.69 for Illinois Agility Test and g = 1.61 for Yo-Yo Intermittent Recovery Test Level 2), likely due to elevated blood bicarbonate and pH that enhance hydrogen ion buffering during high-intensity exercise.

Why this might work

When someone takes sodium bicarbonate before intense exercise, it increases the blood's ability to neutralize acid. This allows acid produced in muscles during hard activity to move out of the muscle cells more easily. As a result, the muscles stay less acidic, which keeps key energy-producing enzymes working at full speed. This lets the body keep making energy quickly, so the person can run faster and change direction longer without getting tired.

    Taking baking soda before a soccer drill three days after a tough workout helped players run and change direction better than those who didn’t take it, even though their muscles were still sore. It likely helped by reducing muscle burn during intense play.
