摘要：

We studied the moderating effects of cardiorespiratory fitness and physical activity on heart rate and blood pressure responses to psychophysiological stressors and the carotid-cardiac baroreflex in young normotensive women with a parental history of hypertension (n=31). Testing occurred during the follicular menstrual phase. Subjects were divided into high versus moderate (46.6+/-6.5 versus 35.9+/-1.9 mL.kg(-1).min(-1)) VO2peak and high versus moderate (1217.7+/-98.4 versus 1015.5+/-49.4 J.kg(-1).wk(-1)) physical activity groups. The groups did not differ in heart rate or blood pressure responses to mental arithmetic or the cold-face test. However, the highly fit women had longer maximal R-R intervals compared with the moderately fit women when the carotid-cardiac baroreflex was stimulated by negative pressures applied to the neck during resting conditions (P<.01). The carotid-cardiac baroreflex was
