Several research studies have investigated effects of bicarbonate supplementation on athletic performance.  During high intensity exercise, acid production (and resulting acidic stress) impairs energy metabolism and muscle contraction.  Theoretically, alkalizing agents, such as bicarbonate, should restore the pH level, delay the onset of fatigue, and improve endurance during high intensity exercise.  Improvements in acid buffering and performance in sprints has been documented, but less is documented relating to endurance at the anaerobic threshold (AT), metabolic acidosis, or muscle recovery the day after exhaustive exercise.

Gina Kolata’s May 16, 2006 New York Times article “Lactic Acid Is Not Muscles' Foe, It's Fuel”, gives some very valid and important insights into athletic performance and exercise metabolism.  Dr. George Brooks proved after developing a much more complex metabolic model that lactic acid is an energy source for the muscles (as well as the kidney, heart and brain as was previously known).  Prior to Dr Brooks' study lactic acid had been identified as the “limiting factor” in intense muscle contraction causing the “burn” experienced when pushing the limits of conditioning. But, lactic acid is not the problem; it is a “marker” for acid generation in the active muscle.  For every molecule of lactic acid formed during exercise, excess hydrogen ions (protons) are created thereby increasing the acidity within the muscle cell.  If these protons are not addressed, the pH in the muscle region is decreased to the point that it creates a “burn” and slows down energy metabolism in working muscles.
