Yes, likewise, it was great to hear from you.
To clarify your point on aerobic vs. anaerobic; I think Lydiard perhaps over-simplified things a bit here. What he's talking about is that during aerobic exercise, one molecule of glucose would produce 34 ATPs compared to anaerobic exercise producing 2 ATPs from one glucose molecule. Therefore aerobic exercise is 17 time more "efficient" (rather than "effective") because you're using up glucose less quickly (during aerobic exercise). Actually I know he said "19 times" and somebody else can clarify the exact numbers. But the important point is that aerobic exercise is much more efficient way to train than anaerobic exercise.
"one molecule of glucose would produce 34 ATPs compared to anaerobic exercise producing 2 ATPs from one glucose molecule. "
hmmm, I have always wondered, just how anaerobic we have to be to produce only 1 1/17th of our aerobic ATP.
presumably the last few strides of one of Michael Johnson's world records.
Anyway Nobby, back to the original topic. The reason why I think Arthur was and is such a great influence is because he is saying to every runner - if you do this this and this you will run fast. He is speaking, not just to the seeming talented youngsters, but also to the slow runners and saying - you can be a very fast runner.
That is truly inspired and inspiring coaching.
