The Claim
Sodium bicarbonate at a dosage of 0.3 g/kg body weight increases post-exercise blood lactate levels to 15.1 mmol/L in non-professional cyclists, indicating enhanced hydrogen ion buffering capacity during high-intensity exercise and reduced intramuscular acidosis.
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.
Taking sodium bicarbonate at 0.3 grams per kilogram of body weight before exercise raises blood lactate levels to 15.1 mmol/L after exercise in non-professional cyclists, which corresponds to increased buffering of hydrogen ions and lower muscle acidity during intense effort.
See the scientific wording
Sodium bicarbonate at 0.3 g/kg body weight increases post-exercise blood lactate levels to 15.1 mmol/L in non-professional cyclists, suggesting enhanced hydrogen ion buffering capacity during high-intensity exercise, which may delay fatigue by reducing intramuscular acidosis.
When sodium bicarbonate is swallowed, it enters the blood and raises the level of bicarbonate ions, which pull hydrogen ions out of muscle cells. This reduces acid buildup inside the muscles, allowing more energy to be made from sugar without slowing down. As a result, more lactate builds up in the blood because the muscles keep producing it, and the person can keep exercising longer before getting tired.
What the research says
1 studyTaking a specific dose of baking soda before cycling helped non-professional riders pedal longer and left more lactate in their blood, which means their bodies were better at handling the acid that builds up during hard exercise.
