Special Episode – Ketones and Bicarbonate with Dr. Chiel Poffe - Science of Getting Faster Podcast
Subscribe to the all-new Science of Getting Faster Podcast! - Exogenous ketones are lauded by many for their endurance performance enhancing properties, but their impact on blood acidity is detrimental to performance and can even counteract their otherwise positive effects. Dr. Chiel Poffe and his partners conducted a study to learn if Bicarbonate Unlocks the Ergogenic Action of Ketone Monoester Intake in Endurance Exercise, and what they learned was surprising. Tune into this episode to learn the science behind ketones and bicarbonate, and how to introduce them into your training regimen to get faster. * Continue the discussion on the TrainerRoad Forum: * Submit a study, researcher or topic to be covered on the Science of Getting Faster Podcast: ---------------------------------------------------------------------------------------------------------------- ABOUT TRAINERROAD — CYCLING’S MOST EFFECTIVE TRAINING SYSTEM TrainerRoad makes cyclists faster.
