How and under what conditions does the training effect occur?

Consider what happens with intense muscle work. Intensive biological oxidation of organic substances leads to the formation of a large number of ATP molecules that are involved in muscle work. Muscular work occurs due to the breakdown of ATP molecules with the release of energy. After its completion, usually a significant supply of unspent ATP molecules remains in the muscle fibers. Due to these molecules, the lost structures are restored, and there are more of them than there were at the beginning of the work. This phenomenon is called the training effect. It occurs after intense muscular work, provided sufficient rest and good nutrition. But there is a limit to everything. If the work is too intense, and rest after it is insufficient, then the restoration of the destroyed and the synthesis of the new will not be. Therefore, the training effect will not always manifest itself. Too small a load will not cause such a decomposition of substances that could accumulate many ATP molecules and stimulate the synthesis of new structures, and too hard work can lead to a predominance of decomposition over synthesis and to further depletion of the body. The training effect is provided only by the load at which protein synthesis overtakes their breakdown. That is why for a successful workout the effort must be sufficient, but not excessive. Another important rule is that after work, a compulsory rest is necessary, allowing you to restore what was lost and get a new one.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
