Andy Coggan said:Quoted message said:If the best coach in the world can be the best without understanding the science of exercise,
then I have to wonder about the value/correctness of the science. It's kind of like saying that
someone can be the best aeronautical engineer without understanding the science of mathematics
and physics.
It is the value that you should wonder about, not the correctness. As
Since the purpose of sport science is to understand in order to maximize athletic performance, I'd
wonder about both at the same time and for the same reasons.
Quoted message said:Kurgan pointed out, the skill set required to be a good coach (not trainer) is quite large, such
that you can be quite successful even if you are weak in one particular if you are excellent in
others. Thus, being
Agreed--but I would expect that a good coach would need to know some minimum of sports science or
his other good qualities wouldn't do much good.
Quoted message said:The relationship between exercise intensity and duration is continuously curvilinear, so
identifying any specific intensity as a "threshold" of one sort or another requires taking at
least a minor liberty. Nonetheless, you
It's a matter of definition, not liberty.
Quoted message said:can describe exercise performance quite well based on a quite simple model of some critical power
plus an anaerobic work capacity. Moreover, critical power determined on the basis of such
functional testing correlates quite highly with more invasive/"scientific" measurements of
threshold, e.g., based on blood lactate measurements. (This is why I've advocated
According to my definition of "threshold", there would be no direct way to measure it. It certainly
wouldn't be measured by some lab result (everyone can tolerate different levels).
Quoted message said:functional field testing over lab testing for individuals who own powermeters - see the chapter I
wrote for USAC.) So I would agree with everything you've written above, except for one very
important aspect: fatigue during exercise is multifactorial, i.e., cannot be blamed on lactate
accumulation alone (if at all).
I never said it wasn't multifactorial. On the contrary, I specifically implied that it was. The
point is that we can define terms that isolate single factors, ignoring others, even if those terms
are not found in "pure" form in the subject. LT is a perfectly reasonable term, properly defined.
And it's also not directly measurable.
Indeed, one of the major purposes of a science is to isolate factors for study. Do you think there's
any object in the universe that perfectly adheres to "F=ma"? No--but that doesn't make it "false".
It's a true description of an aspect of the object's behavior. That truth isn't undermined by the
fact that when applying the formula to a specific object, we must bear in mind that there are other
factors effecting it--after isolating all of the factors, we must re-integrate them for application
to a particular subject. The fact that any one of them alone isn't good enough to "perfectly"
predict behavior is irrelevant.
