Well, biggest part of the battle would be identifying and quantifying all the elements that affect out movement, then our movement through the water. Also, one would have to understand and mathematically quantify the limits of what the human body is capable.

Some of the problems in the setup of the whole thing is that scientifically we are still dealing with couple of unknowns... First would be the potential limits of what the human body is capable of  (Do I sniff out a huge debate potential here). And, do we take an average human body, or do we attempt to model an ideal athlete, and what is an ideal athlete?  (yeap, that could create a mega-debate just there)

The other problem is that certain elements of water&amp;#39;s physical properties (like some details of turbulent flow and water viscosity)are still fuzzy to scientists. Some good research potential there.

It would be a very interesting exercise to conduct some tests and then try to scientifically model the extremes.
I&amp;#39;m guesstimating doing this would only be about 20 times as complex as designing a space shuttle ;)

Isn&amp;#39;t there a university somewhere that is doing this kind of research already?

Would the record progression over the years not reflect those things that you say are being assumed to be held constant from this point on?  Have there not been paradigmatic shifts in technique, training, rules, or other variables over the years that the records have been kept?  And, therefore, nullify that argument that one would need to assume no shifts in technique, training, rules etc?

One other thought.

It&amp;#39;s a very interesting question.  Perhaps if someone with algebraic skills and the history of the 100 m world record (this might be a better distance to look at because more people have swum it), you could plot the performances over time.  I would assume the rate of improvement has been slowing, and you might be able to come up with some sort of asymtote type line we&amp;#39;ll likely never, as a species, bust through.  


The problem is that while this is a valid mathematical exercise, it is a bit problematic as a useful exercise. The reason is that this assumes that there can be no paradigmatic shifts in technique, training, rules, or other variables. Still, it might be fun. If I can find a site with the records progression and I have a few minutes (not likely at this time of year,  but...), I&amp;#39;d like to look at this problem.

I suspect that the theoretical limit is more complicated and based on a combination of the following:
    a) How fast can one react to the starting signal.
    b) How far can one go in the air at the start.
    c) What is the theoretical limit for underwater speed given one&amp;#39;s anthropometric data, up to the legal limit for staying under water.
    d) What is the theoretical limit for speed for being on top of the water. (Approx 1 body length per second, I believe.)
    e) How quickly can one make a flip turn.
    f) How much velocity can be generated off that flip turn and how much streamlining can be affected off the turn.

As was discussed in another thread, I&amp;#39;d bet that all things being equal, height will be a strongly correlated factor (it might have a slight negative correlation for a) and e)).

Sort of and no.

For past events, if you have no knowledge other than the date a record was set and the time, all you can do is see how far it deviates from what might have been &amp;quot;expected&amp;quot; at that time and then set a threshold beyond which we decide that something earthshaking has occured. For example, if we go back far enough to when the 100m record was done as breastroke and then see the first time the record was set as crawl (or some variant), I&amp;#39;d bet the this would give a deviation on the extrapolation of the breaststroke curve that would be very sharp. But without knowledge of exactly what occured to get that deviation you can only give a mathematical interpretation of &amp;quot;paradigm shift&amp;quot;. With knowledge of all paradigm shifts, then you can come up with a closer definition of these shifts, but again, you can&amp;#39;t define them with certainty even then. (Example: A genetic mutation, a la the Foundation Trilogy, occurs.)

As to the future, although you can look at the effect of a change of x.x standard deviations off an extrapolated curve, it presupposes that this will, or even can, occur. So, for example, if we presuppose that a new technique will be invented that supercedes the crawl, we can get a rough approximation based on the past. But, is it likely and is it likely to be of that magnitude? Probably not.

If I have some time on Monday, I will try to investigate this a bit.

No, the shifts of yesterday can not predict the shifts of the future. For example, in the pole vault, poles were originally bamboo and then they went to steel. Despite the fact that people assumed that there would eventually be a change in materials to something better, no one then could have forseen the degree to which fiberglass and composites could have changed things. As another example, look at the backstroke and what Berkoff (sp?) did with his underwater start. That was almost completely unexpected from what had gone in the past. There are other analogies: Fosbury flop in the high jump, Mexican technique in the racewalks circa 1974-1976, etc. Sadly, the development of better performance enhancing drugs will play a role as will the eventual use of *shudder* gene therapy. All these can completely throw away any possibility of prediction of a limit based on past and present performances.

The Asimov Foundation analogy is a very good analogy, BTW, if you are familiar with it. (Highly recommended, but you can NOT skip ahead and read the end or you will have to do breath-holding sets till you puke.)

So, if Ian Thorpe and Janet Evans get married and have kids with size 28 feet, take hideous drugs, come up with a new tfreestyle echnique and eat their Wheaties, we can expect the middle and distance world records as we understand them, to go bye-bye in a dramatic, not incremental, way.
