Perhaps you could explain how a higher RBC doesn't mean that more oxygen can be carried for each breath? Or how an improved aerobic capacity requires a runner has to breath harder than when they had lesser aerobic capacity? I'm sure you could produce citations. And another proving the earth is flat, while you are about it.
I don't make any of these claims, as I haven't yet seen any expert discussion, nor the basis supporting the discussion, on the connection to the breathing rate, either during or post-exercise, associated with an alleged higher throughput capability of oxygen. Once I have seen the expert discussion, and the supporting data and observations, I would be in a better position to form a reasoned opinion, and explain the basis for it. You suggested an inverse relation: higher oxygen throughput leads to reduced breathing. You said it seems too logical. I said this inverse relation seems counter-intuitive.
Recall it was you who made a claim about the significance of breathing on page 1. A fundamentally basic part of intelligent discourse is for you to be able to provide the basis and foundations for your own claims. Telling me that I cannot comprehend a basis that has not been presented does not meet that burden.
With respect to the shape of the earth, around 1000 years ago, the Islamic astronomer Abu Rayhan al-Biruni did a mountain top experiment taking measures of the dip-angle to the horizon, relative to a horizontal gaze. From this measurement, and another measurement of angles to the height of the mountain, he used basic geometry to estimate the radius of the earth to a remarkable degree of accuracy, compared to our current estimates today. If the earth were flat, he would have measured a 0-degree dip-angle, and the radius calculation would have resulted in a division by zero, indicating the infinite radius associated with a plane. Anyone can make predictions from their model, and then perform this experiment for themselves, making the results verifiable, and if applicable, falsifiable.
What a relief that an ancient astronomer has assured you the earth isn't flat. You would never have known otherwise.
But in respect of "the earth isn't flat" observations I made about breathing being related to a higher RBC and improved aerobic capacity the only alternative position, if you dispute that relationship, is to accept the propositions in the questions I posed above. Logically you are required to maintain the converse of what I argued. So - go ahead and prove it.
I will remind you what my questions were.
- How does a higher RBC not mean that more oxygen can be carried for each breath?
- How does an improved aerobic capacity require a runner to breath harder for the same effort than when they had lesser aerobic capacity?
How does having a higher aerobic capacity reduce the ventilation rate?
Do you even understand the question?
Because elites don't suck wind like hobbyjoggers.
Not necessarily. Are you familiar with the term ventilatory threshold?
