Effects of resistance exercise on 24 hour ambulatory blood pressure in pre and hypertensive subjects

Abstract

This study was to investigate the effects of resistance exercise in untreated pre and hypertensive subjects. Twenty‐three subjects(62±6yrs) with pre and hypertension were participated in the study. Subjects were randomly assigned to an exercise group(n=11) and a control group(n=6). Exercise group was performed the supervised resistance exercise program with low to moderate intensity(40 60% of 1 RM), 12 repetitions, 2sets, 3 times per week, for 12weeks. Body composition, lipid profiles, insulin resistance, cardiorespiratory fitness, 1 RM test, clinical blood pressure and 24 hour ambulatory pressure were measured at baseline and after 12 weeks intervention. Chest press of 1 RM test was significantly increased in exercise group compared with control group(p=0.020). There were no significant changes in body composition, lipid profiles, insulin resistance, and cardiorespiratory fitness. Clinical blood pressure tended to decrease in exercise group, but 24 hour ambulatory blood pressure was not changed. In conclusion, resistance exercise did not improve clinical and 24 hour ambulatory blood pressure in untreated pre and hypertensive subjects.
