Final answer:
In Hans Selye's General Adaptation Syndrome, the period after training with a temporarily increased performance capacity is known as Supercompensation, which occurs after the resistance stage.
Step-by-step explanation:
The General Adaptation Syndrome (GAS) principle, as developed by Hans Selye, includes three stages: alarm reaction, stage of resistance, and stage of exhaustion. The correct answer to the question is d) Supercompensation. This is the period after training when the trained function has a temporarily higher performance capacity than it did prior to the training period.
It is not one of the original stages named by Selye but is commonly associated with the period after resistance where the body overcompensates for the exerted effort during training to build up additional capacity for future exertion.In Hans Selye's General Adaptation Syndrome, the period after training with a temporarily increased performance capacity is known as Supercompensation, which occurs after the resistance stage.
