Introduction: Although intensive, repeated and perennial, physical stress of training generally does not represent a health hazard to professional athletes. Adaptation to such stress is presumed on multiple levels, but still not fully defined. Our aim was to analyze specificities of hypothalamic-pituitary-adrenal (HPA) axis response and adaptation to physical stress in professional athletes.Subjects and methods: We exposed 55 professional male athletes t...

Activation of hypothalamo-pituitary-adrenal (HPA) axis is a common feature of endocrine responses to stress, with cortisol secretion as an end product of this activation. Acute rise in cortisol level during stress is of utmost importance for metabolic adjustments, immune system adaptations, cardiovascular responses and muscle tissue remodeling. But since chronic hypercortisolism has many deleterious effects, scientific interest has started focusing around different biological ...

Introduction: Prolonged exposure to stress has a modifying effect on activity of hypothalamo-pituitary-adrenal (HPA) axis. This is a protective adaptation aimed to diminish potential deleterious effects of chronic hypercortisolism, and to diminish effects of acute exposure to heterotypic forms of stress. Our aim was to analyze modes of cortisol response to acute physical stress in groups of different stress categories and sex.Subjects and methods: Study ...
