During our swimming careers we have all experienced the feeling of "being in-shape" and not quite "in-shape".
My question is this; From a physiological or Kinesiological standpoint, what is happening in your body when you can so easily go from being in-shape to losing that in a matter of a week or two?
I'm an old masters swimmer now but even swimming High School, Club or College whenever I would go on a vacation or get sick for a week, it took two - three weeks to get back to where I was before the vacation or sickness?
What is happening in our body when we can swim a 1:07 BR and then two weeks later can't break 1:10???
Thanks in advance for your answers and opinions...

Hypothetical question:
I wonder if you can retrieve plasma from your body while in shape, sufficiently store it and then put it back into your body prior to a big meet to increase plasma volume? Would Michael Phelps' plasma help me?
Sorry if these questions are odd but i love the science behind swimming! Your questions isn't odd at all.
Plasma is mostly made of water, no hemoglobin. So by drop in blood plasma I really mean drop in converted hydration.
I freely use the word converted here. What I really mean is that when you drink, the fluid is used by the body for various short/mid term usages. Part of the fluid we drink as part of re-hydration process goes into blood stream in the form of plasma.
That along with the size and power of your heart mainly affect what some call : the cardiac output. When this drops, the very first fitness component being affected is your Vo2Max, which depends a lot on blood circulatory functions.
