Abstract:
:To evaluate factors influencing hemodynamic responses to psychological and physical stress, 117 normotensive college students were studied. The standardized tests included arithmetic, Stroop word-color, mirror draw, isometric handgrip and cold pressor challenges. The responses of blood pressure and pulse during the tests were compared to the baseline measurements. All the challenges produced a significant (P less than 0.01) increase in systolic and diastolic pressure and pulse rate, with the greatest increase being seen with the isometric handgrip test. The increases in the systolic and diastolic pressure and the heart rate to the psychological stressors were highly correlated (P less than 0.001). The responses to the physical stressors were correlated for the diastolic pressure (P less than 0.01) and the heart rate (P less than 0.001), but not for the systolic pressure. The responses of the systolic and diastolic pressure, but not the heart rate, to the isometric handgrip correlated with the responses to the psychological stressors. The responses of the diastolic pressure and the heart rate, but not the systolic pressure, to the cold pressor stimulus correlated with the responses to the psychological stressors. The gender influenced the response to all the stressors with males having a greater (P less than 0.05) blood pressure response and a lesser (P less than 0.001) heart rate response than females. Black subjects had greater blood pressure responses to the cold pressor test and a greater diastolic pressure response to the handgrip, but there were no observed racial differences in the responses to the psychological stressors.(ABSTRACT TRUNCATED AT 250 WORDS)
