"The Cost of Adaptation

A number of Soviet and Russian textbooks, from the 1970s until today, cite a study of young rodents undergoing an intense swimming regimen — one hour a day for ten weeks.(2) Their heart mass increased while the mass of their kidneys and adrenal glands went noticeably down, and so did the number of the liver cells.

In other words, while the training increased the functional capacity of the heart, it simultaneously reduced the capacity of several inner organs. If later the “athletes” from the study encountered significant physical loads, they would be better prepared to handle them and survive compared to their untrained peers. If, on the other hand, the challenge were directed at the liver or kidneys (through a change of food, an increase of sodium intake, etc.), the hard training rats would be at a disadvantage compared to their lazy brothers and sisters.

This phenomenon is called the cost of adaptation.(3) The cost can be exacted from the systems of the body directly loaded by the stressor — or from other system(s) not directly involved in dealing with the stressor.(4)"

So, is this an assumption that size matters?
Do they know that those organs that were reduced in physical size were also reduced their capacity to function?

When people exercise and reduce net calories, they lose mass, but they are likely to become more healthy.
Maybe their kidneys, adrenals and livers became more healthy and efficient?


Asking for a friend.

" You Must Rob Your Health To Pay For Your Sport " in the article seems more layman terms to me, it makes sense. Start with a good foundation in general fitness, don't force Your rate of progress, and train in moderation. Don't shoot for PR's or Gold Medals every training session. It's that simple if You want health. If You want pure performance then You will pay the price in the end. "Because high adaptation cost is experienced especially by specialist athletes and people who perform hard physical labor." Your body only has so many miles on it, If You wear it out, all You will be doing is remembering when You use to do something.
