Adaptation Resource in the Context of Training

Selye's concept of adaptation energy and modern understanding thereof: managing training and recovery to optimize adaptation energy expenditure and enhance training efficiency.

What is "adaptation energy" according to Selye
Hans Selye, a smart guy who came up with the concept of stress, introduced the idea of adaptation energy. Its concept looks like the following:
- it's not calories and not ATP, but a conditional resource of the body that is spent on adaptation to any stress - cold, hunger, training, infections, mental stress;
- this resource is finite: the more we spend it without recovery, the closer we are to the stage of exhaustion. In the model of adaptation energy, the following stages can be distinguished:
- Alarm stage - the body mobilizes, but at the same time spends part of the adaptation energy.
- Stage of resistance - the body has adapted and maintains a new level of load.
- Stage of exhaustion - the resource is depleted, and the system starts to fall apart (diseases, overtraining, burnout).
