A Comparative Study to Find the Effect of Aerobic Exercise Training Versus Resistance Exercise Training in Adults with Pre-Hypertension

Abstract

Background and Objectives: In 2003, the Seventh Report of the Joint National Committee (JNC 7) definedprehypertension as a systolic blood pressure (BP) of 120–139 mmHg or a diastolic BP of 80–89 mmHg in adults18 years and older. Prehypertension seems indeed to be a precursor of hypertension, associated with manyadverse outcomes. The conversion rate of prehypertension to hypertension over 4 years was 30%. Many studieshave focused also on the predictors of progression from prehypertension to hypertension. However, the resultswere controversial, and Therefore, we performed this study in order to find out and compare the effect of aerobicand resistance exercise training in adults with prehypertension.Method: This study was done on 40 subjects who were randomly divided into two groups, Group A (N=20) with mean age49.45 (SD±5.586) and Group B (N=20) with mean age 45.25 (SD±4.375) where Group A was given aerobic exercise andGroup B was given resistance exercise. The outcome measure was taken as BP. Exercise session for both group was for 5 days(40minute/day) per week for 4 weeks.Result: Statistical analysis was done using SPSS version. The paired ‘t’ test was used to find the effect of aerobic andresistance exercise in prehypertension. Result showed significant reduction in blood pressure in both group. in aerobic groupthe pre and post effect of aerobic exercise is mean=2.30,SD=1.658 since the significance value for changes in all measurementare less then 0.05(p=0.00) and the average difference in 3.25 per subject in aerobic group and in resistance group the pre andpost effect of resistance exercise is mean=2.50,SD=1.638 since the significance value for changes in all measurement are lessthen 0.05(p=0.00) and the average difference of 2.95 per subject in resistance group. These result showed significant reductionin BP (p˂0.05) in both aerobic and resistance group.Conclusion: The study concluded that the aerobic exercise and resistance exercise both were effective inprehypertension. And these results also suggest that there are no significant comparative difference betweenaerobic and resistance group.
