Misunderstood Science of Running with Heart Rate

Описание: Dive into the science of heart rate with me, Dr. Will, as I explore the intricacies that even seasoned athletes find baffling. Today, we're tackling the phenomenon of cardiac drift and its impact on our training, illuminated by my own experiences across a spectrum of races.

In this video, I'm breaking down the cardiac output equation—Heart Rate x Stroke Volume = Cardiac Output—and explaining its relevance to our everyday training. I'll show you how a simple zone 2 run can escalate into a higher heart rate zone without any change in your effort, all due to the body's response to heat and hydration.

I'll also discuss the enigmatic O2 slow component, revealing how it affects our performance during a steady-state effort like a marathon and what it tells us about our true running fitness.

And for those short, sharp intervals? I'll explain why heart rate might not be the best measure and how to avoid the common mistakes runners make when they're chasing those heart rate numbers.

So, if you're ready to gain a deeper understanding of your heart rate and how to use it effectively in your training, you're in the right place. Don't forget to subscribe for more insights that blend scientific knowledge with practical running wisdom.
