Document Summary

Exercise- stress research: effect of exercise on stress response studied in a variety of areas, cardiovascular fitness, hypothalamic-pituitary-adrenal (hpa) cortical axis response. Cardiovascular fitness: results are inconclusive, mechanisms responsible for the sympathetic aspect of the psychosocial stress response (ex. Ne and e) and the response to exercise stress may be different: research does suggest that aerobic fitness may have stress-buffering effects to psychosocial stressors, ex. Hypothalamic-pituitary-adrenal (hpa) cortical axis: traustadottir et all (2005) - in textbook, compared fit and unfit older women"s responses to stress tests. Found that fit women had lower cortisol response: concluded, aerobic fitness affects the hpa axis by reducing the cortisol response to psychosocial stress. Reactivity vs recovery: evidence suggests that fitness or exercise training may provide a more rapid recovery from the stressor once it is no longer present, trained individuals, lower hr response and decreased cortisol level in recovery.
