| AIMS . While the physiological effects of stress are advantageous when the response occurs to prepare the body for “fight or flight,” they can be detrimental if long lasting or repeated without outlet. One of the mechanisms that may link stress to illness is arousal of the sympathetic nervous system (SNS) that occurs during the stress response. Through the SNS, the stress response prepares the individual to deal with the stressor physiologically. Problems arise when the individual is unable to, or perceives she is unable to, escape the stressor. Stress reactivity was assessed in aerobically fit (n = 20) and unfit (n = 18) females during the follicular phase of the menstrual cycle. METHODS . Participants completed the survey sheet and provided a urine sample for catecholamine analysis before and after mental stress testing, Strop Color-Word Test. Blood pressure and heart rate were measured during mental stress testing. RESULTS. Fit and unfit participants differed significantly in baseline heart rate but not in stress reactivity or in state or trait anxiety. CONCLUSION. These data suggest that aerobic fitness does not attenuate the stress response in women prior to menopause. |
