“…As our total sample included healthy young men, the results cannot be generalized to the population as a whole, and particularly not to older persons. However, not only is there evidence that aging is associated with stronger HPA responses to stress but there are also findings indicating a robust attenuating effect of moderate physical activity on these responses in elderly people (Traustadottir et al, 2005). Thus, changes in HPA axis reactivity induced by physical activity may even be more pronounced in older compared with younger subjects.…”

“…Increasing fitness is likely one of the most potent interventions for restoring A/C balance and can improve well-being. Long-term exercise can decrease cortisol and increase DHEA, GH, and IGF-1, 154 and is associated with reduced cortisol reactivity 155 and cardiovascular reactivity to acute stress, 156 as well as reduced anxiety 157 and depressive symptoms. 158 Psychosocial interventions have been effective in improving A/C balance.…”

Chronic stress can affect human health through a myriad of behavioral and biochemical pathways. Τhis review focuses on some key hormonal and metabolic pathways that appear important today. In modern society, we are faced with excessive psychological stress, as well as an epidemic of overeating, and the two together appear to have synergistic effects. Chronic stress can lead to overeating, co-elevation of cortisol and insulin, and suppression of certain anabolic hormones. This state of metabolic stress in turn promotes abdominal adiposity. Both the direct stress response and the accumulation of visceral fat can promote a milieu of systemic inflammation and oxidative stress. This biochemical environment appears to be conducive to several cell aging mechanisms, mainly dampening telomerase and leading to telomere length (TL) shortening and cell senescence. Immune cell telomere shortness is linked with many chronic disease states and earlier mortality. In this way, chronic stress may influence a variety of diseases through a biochemical cascade leading to immune cell senescence. Certain psychological temperaments at high risk of this stress cascade (mainly anxiety prone), gene-environment interactions, and potential interventions for interrupting the stress-aging cascade are discussed.

“…For example, Traustadottir and colleagues examined two groups of adult women who were subjected to a standardized psychosocial stressor. They found that the cortisol response to the stressor was substantially lower in the physically more active women compared with those who were more sedentary (i.e., not very physically active) (FIGURE 6) [40]. This example only describes an acute stress exposure.…”

“…This example only describes an acute stress exposure. By contrast, it is known that chronic exposure to psychosocial, environmental or traumatic stressors can have long-lasting, deleterious effects on a person's psychological and physiological health, in both adults and children [21,35,40]. The suggestion that exercise may have a carry-over effect on the acute stress response to other stressors suggests physical exercise could, perhaps, be part of an intervention strategy to deal with some chronic stress-related health problems in the young and old alike.…”

In this article, the physiological impact of one form of stress -physical exercise -on the neuroendocrine system will be discussed. The specific intent of the review is to present an overview of stress endocrinology, the conceptual models associated with this area of study, and a discourse on the dual role of exercise as both a stressor and a modifier of stress within the neuroendocrine system. These points are addressed with respect to the current research literature dealing with exercise endocrinology in an adult population. Keywords disregulation; endocrinology; hormones; physical activity; sport Stress is something experienced by all of us, no matter who we are, and it has both a positive and a negative effect on our lives. Modern society has created an environment where there are tremendous opportunities to experience both negative stresses (distress) as well as positive stress (eustress) on a daily basis [1,2]. Such stressful encounters have profound impacts upon the physiological workings of the human body, both in constructive and destructive fashions. One physiological system that is extremely reactive to stress is the neuroendocrine system [1,2]. In fact, many clinicians and researchers use the responses of the neuroendocrine system as a means of assessing the stress effects and reactivity of the human body.Physical exercise is an activity that is known to provoke large and diverse stress responses within the neuroendocrine system. However, chronic exercise training is also known to cause abatement in the stress responses of the neuroendocrine system to certain forms of stress. The intent of this article is to provide an overview on these somewhat paradoxical effects of physical exercise upon the neuroendocrine system. Specifically, the intended purpose of this review is twofold: to provide a brief overview of stress endocrinology and the conceptual models associated with this area of study; and to address the dual role of exercise as both a stressor and a modifier of stress within the neuroendocrine system, both in acute and chronic exposure settings.
