Welcome to the Huberman Lab podcast, where we discuss science and science-based tools for everyday life. I'm Andrew Huberman, and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine. I'm pleased to announce the launch of a new podcast from our team here at Huberman Lab. The podcast is Perform with Dr. Andy Galpin. Most of you are likely familiar with Dr. Andy Galpin from our six episode guest series on improving your physical fitness and health. For those of you not familiar with Andy, he is a professor of kinesiology at Cal State Fullerton and an expert on exercise physiology and human performance. This new podcast, Perform with Dr. Andy Galpin, will explore all aspects of human performance.
It shares the latest science and provides practical tools on things such as how to improve cardiovascular health, how to build strength and muscle mass, how to maximize your recovery with the nutrition and supplementation, and much more. What follows is episode one of Perform with Dr. Andy Galpin. If you enjoy it, I encourage you to go and subscribe to it wherever you're listening now. And now, episode one of Perform with Dr. Andy Galpin.
The science and practice of enhancing human performance for sport, play, and life. Welcome to Perform. I'm Andy Galpin, a professor of kinesiology in the Center for Sport Performance at Cal State Fullerton. In today's episode, we're going to be talking about the heart. And I'd like to start with a very simple question. And that is, why do you breathe? Now, that may have caught you off guard, and so I'll let you think about it for a quick second. Why is it that you breathe? The first couple of answers probably rushing to your head are something like, well, if I don't breathe, I'll die. And yes, that's true. But why? Why is it that if you don't breathe, you'll die? With that prompt, you're now probably thinking about, well, I've got to get oxygen into my system because oxygen is needed as a fuel for metabolism to produce energy and to keep my cells and heart and brain alive.
Well, that's not exactly the right answer. Of course, oxygen is critically important and you will die without it, but there are many other things going on that determine how you breathe, why you breathe, how often you breathe, and why that's vital to both your health and performance. Given that the focus of this show is to discuss the science and physiology of maximizing performance, I think it's pretty prudent of us to then spend a little bit of time learning more about how and why your heart functions. In order to do that, we're going to cover what I call the three I's. The first being investigate. Another way of saying, how do I understand and analyze whether or not my heart is functioning at the highest level possible?
The second I is interpretation. How do I value those numbers? Is that great, terrible, amazing, best in world history, et cetera. And then the third one is intervene, which is a way to say, what do I do about it? How do I improve various markers? How do I reduce others so that I can maximize my overall functionality and performance of my cardiovascular tissue? Or in other words, your heart. In order to do that, we're gonna have to expand our conversation past just the heart itself. This is going to include things like respiratory rate. In fact, I opened up the conversation here by asking you why you breathe. And so we're going to take a look at not only the cardiac function itself, say your resting heart rate, maximum heart rate, cardiac output, VO2 max, and things like that, but we'll also get into other important and relative metrics like your heart rate variability, your respiratory rate, CO2 tolerance, and other things that you need to understand to fully appreciate and then therefore improve
function of your cardiovascular system. Before we get started with all that, though, we need to take a quick step back and go through really what the heart is, how it functions, what it's made of, and that will then give us insights and understanding about how to measure it, interpret it, and then therefore improve it.
