Q

Selye (1950) does training buffer stress?

A

cross-stressor adaptation hypothesis

  • training, induces physical adaptations that generalise domains
  • augmented response to novel stressors results in quicker adaptation
  • minimisation of the stress response during common or chronic stress; preserves NE and Cortisol
