Perform with Dr. Andy Galpin Scicomm Media

In this episode, I discuss the critical importance of building a strong heart and how to do it. I explain why the human body needs to breathe, the importance of cardiorespiratory fitness for sleep and exercise recovery, and its long-term implications for physical health, disease risk, and mortality. I explain how the heart functions, what determines heart rate, why the heart never gets sore, and the unique advantages of cardiac muscle over other muscle types.
I explain how to use the ‘Three I’s’ (investigate, interpret, intervene) to assess and improve your cardiovascular fitness. I explain what VO2 max is (and other related metrics, e.g., heart rate variability), describe ranges based on age and elite performance, and discuss exercise regimens to improve VO2 max.
Listeners of this episode will understand why cardiovascular health is vital for performance and overall health and learn a series of actionable tools to improve their cardiovascular fitness.

In this episode, I discuss the essential role of skeletal muscle in health and performance. I explain what skeletal muscle is made of, how it works, and its role as an integral organ system for physical and mental health. I explain how to focus on skeletal muscle quantity (total muscle) and muscle quality (functionality, speed, power, strength) to ensure you function and perform at the highest levels.
I explain the difference between slow- and fast-twitch muscle fibers and why skeletal muscle is uniquely adaptable to exercise, nutrition, and lifestyle factors. I also explain why resistance training becomes increasingly critical for healthy aging and disease prevention.
I explain how to use the "Three Is" of investigate, interpret, and intervene to determine if you have enough muscle, if it's functioning well, and protocols to improve muscle quality and quantity. Listeners of this episode will understand why skeletal muscle is so essential to care for and how to enhance muscle quantity and quality to optimize physiology, performance, and longevity.

This is Perform with Dr. Andy Galpin. 
I'm Dr. Andy Galpin, a professor of kinesiology at California State University, Fullerton.
With this podcast, my goal is to help you better understand and maximize your own physical performance, leveraging my two decades of experience with top-tier performers, including Olympians and world champions across numerous sports. We'll discuss a range of advanced tools, technologies, and strategies, striking a balance between the forefront of scientific research and simple solutions.
The way we'll do that is by covering what I call the "3 I's". For every topic, we'll explore how to 1) Investigate (i.e., measure), 2) Interpret (i.e., what's good, bad), and 3) Intervene (i.e., change). We'll do this from the lens of high performance, letting you enhance your abilities from good to great.                                  
In the upcoming episodes of Season 1, we'll explore topics like the science of muscle development, how to build endurance, the role of sleep and recovery in high performance, and how to create training programs for strength, improving VO2 Max and cardiovascular health, growing muscle and much more.  
I'll share actionable insights ("do's and don'ts") and I'll discuss the effectiveness of various supplements, training equipment, and technology in elevating mental and physical performance.
While not all of us are elite athletes, myself included, there are many lessons and tools that we can glean from those performing at the highest levels. And remember, as legendary coach Bill Bowerman stated, "If you have a body, you are an athlete." If you're not already, I hope you'll consider starting to train and recover like an athlete. 
Stay tuned for Season 1, launching in Summer 2024.
