As we delve back into the science of running, we've noticed that there are a lot of terms and shorthand we use that may not be familiar to everyone out there. Most of us have heard the terms "VO2 max" and "lactate threshold," but do we understand what those things really mean, or how they relate to our endurance pursuits? For this episode we decided to get back to basics with one of the most knowledgeable exercise physiologists and running coaches in the country, Dr. Jason Karp. Dr. Karp is the author of over 400 articles and eight books on running, and he is the perfect guest to help us develop a deeper understanding of the physiologic parameters that govern performance.
We start out by defining the major parameters: VO2max, lactate threshold, and running economy (9:30), and examine what these parameters actually mean for our physiology (17:00). Then, we discuss the different types of training that we can use to target each of these parameters (19:00), before examining the utility of repeat physiologic testing (29:30) and how these parameters factor into the brain's regulation of performance (33:00).
