Lactate DOES NOT cause fatigue! | #59 - Fast Physiology 11 ft. Dave Schell

In this episode of the Critical Oxygen Podcast, Dave Schell and I discuss lactate and debunk some common misconceptions. We start by talking about how lactate is produced by muscles during exercise, and created to a greater extent when carbohydrate breakdown outstrips the rate at which oxygen can be used in the mitochondria. Lactate does not cause fatigue and actually serves as a beneficial fuel for the body. If you are going to measure lactate for your training please ensure repeated measurements! TAKEAWAYS - Lactate is produced by muscles at all times but when carbohydrate breakdown outstrips the rate of oxygen use in the mitochondria lactate accumulation in the blood is higher. - Lactate does not cause fatigue and actually serves as a beneficial fuel for the body. - Lactate measurements require repeated testing and understanding of individual responses.
