Does Sodium Bicarbonate Make You Faster? w/ Dr. Jason Siegler–Science of Getting Faster Podcast Ep 8

The buffering capacity of Sodium Bicarbonate and Sodium Citrate has been well-studied for their potential to decrease the acidity of our blood during exercise, and ultimately attenutate fatigue.

In a larger effort to reevaluate the hyperhydration strategies in the lead-up to the Tokyo Olympics, Dr. Siegler and colleagues aimed to uncover if buffering agents such as Sodium Bicarbonate and Sodium Citrate have the potential to enhance performance in ways that had not been previously studied.

In this episode of the Science of Getting Faster Podcast, Dr. Siegler, a leader on the subject of buffering agents, joins us to discuss buffering agents and his study The Hyperhydration Potential of Sodium Bicarbonate and Sodium Citrate.
