Adaptation energy, according to Seyle cannot be gained; its amount is determined by birth and the best we can do about it, is to use it efficiently so that minimum adaptation energy be lost "per stressful event".
Correct interpretation of the term adaptation energy is hard because adaptation energy refers to something not tangible but to something, which is the effect of a process, something which should exist because statistical data suggests so.

 General adaptation syndrome
General adaptation syndrome, or GAS, is a term used to describe the body's short-term and long-term reactions to stress.

The main muscular adaptation, resulting from strength training, is the increase in fast-twitch muscle fibers (dense muscle fibers with greater contractile abilities), while the aforementioned aerobic training helps to establish the slow-twitch variety (fibers with a larger percentage of mitochondria, which are more resistant to fatigue).
Adaptation was explained in elegant detail by famous Viennese physician and endocrinologist Hans Selye, in his monumental 1946 paper The general adaptation syndrome and the diseases of adaptation.

It is proposed that refractive errors are outcomes of the physiology of the General Adaptation Syndrome with its consequences on the organism --
Adaptation functions to counteract and minimize the effects of stress, enabling the organism to perform as efficiently as possible.3 In the same vein, the ametropias serve the organism's need for survival and conservation of energy in the visual system.
The current clinical trend in general optometry and ophthalmology is to reduce the visual analytical role of the clinician, even delegating refraction and minimizing visual analysis and virtually ignoring visual therapy.

Curiously, glucocorticoids are needed for the acquisition of adaptation primarily during the alarm reaction, but not so much to maintain the adjustment during the stage of resistance.
In general, the hormonal responses outlined above aid adaptation to environmental change or stimuli; but they are sometimes the cause of disease, especially if the state of stress is prolonged or intense.
The term "adaptation energy" has been coined for that which is consumed during continued adaptive work, to indicate that it is something different from the caloric energy we receive from food; but this is only a name, and even now we still have no precise concept of what this energy might be.

With all this information about adaptation now clearly in mind, let us review Selye's (1946) definition of stress: "Stress is the nonspecific response of the body to any demand made upon it to adapt, whether that demand produces pleasure or pain." Since stress is an adaptation response, we equate it with the general adaptation syndrome.
This maladaptive stimulation of the fight or flight response represents the first phase of Selye's general adaptation syndrome, a long-term physiological response pattern that we equate with the concept of stress.
The end result of the three stages of the general adaptation syndrome is exhaustion and breakdown of one or more organ systems.

The General Adaptation Syndrome CAL package introduces the short term and long term physiological effects of stress.
The package is aimed at students of midwifery principally, but it can also be used by general medical students: the first screen prompts the user to select their student type, and based on this choice s/he is presented with tailored content (midwife students receive more information specific to midwifery).
The General Adaptation Syndrome CAL package represents approximately 1 hour of self-study, and the product itself took approximately 1 month to develop from scratch (the work was spread over 6 months).

This stage is the one in which adaptation occurs and, according to Selye (5), "is characterised by an increased resistance to the particular agent to which the body is exposed and a decreased resistance to other types of stress".
Especially since it is generally accepted that CFS (which is often referred to as "Post-viral Syndrome") is caused or triggered by viral infections such as influenza or glandular fever, the whole debate about exercise does seem rather irrelevant.
