Peter Attia MD - Lactic Acid Myth: Buffering the Real Culprit | Olav Aleksander Bu
The speaker explains that as exercise intensity increases, lactate production rises, leading to a decrease in performance due to the associated hydrogen ions causing acidosis. The hydrogen ions, not lactate itself, cause muscle fatigue by interfering with muscle filament function. To combat this, buffering agents like bicarbonate are used to reduce the impact of lactic acidosis. The speaker mentions involvement in research using bicarbonate in a hydrogel form to improve delivery and effectiveness. This method allows for higher concentrations and improved lactate tolerance, as evidenced by research on athletes like Gustav, who showed improved performance with bicarbonate use.
Key Points:
- Lactate production increases with exercise intensity, leading to performance decline due to hydrogen ions.
- Hydrogen ions, not lactate, cause muscle fatigue by affecting muscle filaments.
- Buffering agents like bicarbonate can reduce lactic acidosis impact.
- Bicarbonate is administered in a hydrogel for better delivery and effectiveness.
- Research shows improved lactate tolerance and performance with bicarbonate use.
