Stress and the neuroendocrine system: the role of exercise as a stressor and modifier of stress.

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.
