Purpose. The purpose of this study was to determine the effect of caloric expenditure (300kcal), using two intensities, 50% and 70% of heart rate reserve (HRR), on post-exercise hypotension (PEH) in prehypertensive (PHTN) and normotensive (NORM) adult subjects, not on blood pressure (BP) medication. Methods. Fifteen adult men and women (5 male, 10 female), prehypertensive (PHTN), stage I hypertensive (HTN) and normotensive (NORM) were recruited for this study. Participants were required to record their food intake for three days prior to each testing session. Each subjects' exercise capacity was determined using the HRR method. Intensity levels of 50% and 70% were used to expend 300 kcals per testing session. Subjects participated in two experimental sessions one at 50% and one at 70% intensity of their predicted HRR. Experimental exercise sessions were performed after a 24-hour exercise restriction and at least 3 days apart, for duplication of 3-day food intake. Blood pressure monitoring occurred prior to exercise after 5 minutes of seated rest, standing prior to exercise, immediately post exercise 10, 30, 60, 90 and 120 minutes post exercise. A repeated measures analysis of variance with time, treatment (PHTN & NORM), as factors was used to determine the main effect of exercise intensity on systolic and diastolic blood pressure. A Tukey-post hoc test was used to identify significant differences when a significant F-ratio was obtained. All values are reported as means +/- standard deviation. Results. No statistically significant blood pressure responses in either the NORM or PHTN groups were found. No correlations found between intensity level of exercise session and blood pressure response. No correlations found between caloric expenditure and post exercise hypotension. Conclusion. The data from this study indicates that a caloric expenditure of 280 may or may not be sufficient to elicit PEH as no correlation was found. Also, no correlation was found between exercise intensity and PEH.
