I stand by my comment that aerobic fitness can be achieved very quickly.
Aerobic fitness = mitochondrial mass, and it takes a maximum of six weeks to achieve this, much less in someone who has been keeping in good shape.
However, mitochondrial mass will not in itself make you a fast middle and long distance runner. This is why it is important to emphasize running economy by doing interval training and/or tempo runs regularly.
So 12 weeks minimum might be a necessary time frame for aerobic conditioning in terms of the speed requirements of racing, but it is not necessary for aerobic fitness, these are two very different things.
Anyways Pete, you were a decathlete, so my question to you is; how many aspects of track and field do you coach?
I coach them all wellnow. Track and field is a single discipline with many facets and for me is ultimately about what is involved in training a human being completely, without any gaps.
Your argument that aerobic fitness is exactly equal to mitochondrial mass is something you will have to further convince me of Wellnow.
Your other argument that much of the improvement in performance is attributable to factors other than improvements to aerobic fitness has strong merit. There are improvements in running economy and improvements in racing skill and improvements in strength as well as improvements in speed. Also improvement in psychology. Everything really, except no improvement in aerobic fitness after 6 weeks. This is hard to swallow. Do the other factors plateau after 6 weeks as well?
cheers
Pete
