In high intensity anarobic and arobic conditioning, your heart beats faster. oxygen utilization in muscles is going to go up. The amount of blood being returned to the heart actually causes an eccentric loading of one of the muscular walls of the heart. Because of the additional work that your muscles and nerves are doing, it has the effect of creating an eccentric loading,. A kind of pushing of the wall the left.
This episode I discuss endurance: our ability to perform effort over extended amounts of time. I describe the four kinds of endurance: muscular endurance, long duration (single-set) efforts, and the two kinds of high intensity interval training (HIIT). I discuss efficiency of effort and maximizing quality of effort, and a hydration formula. I review how our heart literally gets stronger when we oxygenate muscles properly. I also discuss motivation for long bouts of work and the visual physiological basis of the "extra gear" we all can leverage for effort. Finally, I review how accelerating as we fatigue can allow us to access untapped energetic resources.
