Reaction of pituitary-adrenal and autonomic nervous systems to stress in trained and untrained elderly people.
The changes of hormonal and autonomic nervous systems in trained and untrained elderly people were studied. An exercise tolerance test was used as a model of physical stress. Elderly people were more sensitive to the influence of stress factors. The hemodynamic reaction at the same workload was more economical in trained subjects. Also, the reaction of the autonomic nervous system and pituitary-adrenal system was less pronounced in trained elderly people. It was established that physical training in aging increases the resistance to stress.
