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) defined
prehypertension as a systolic blood pressure (BP) of 120–139 mmHg or a diastolic BP of 80–89 mmHg in adults
18 years and older. Prehypertension seems indeed to be a precursor of hypertension, associated with many
adverse outcomes. The conversion rate of prehypertension to hypertension over 4 years was 30%. Many studies
have focused also on the predictors of progression from prehypertension to hypertension. However, the results
were controversial, and Therefore, we performed this study in order to find out and compare the effect of aerobic
and 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 age
49.45 (SD±5.586) and Group B (N=20) with mean age 45.25 (SD±4.375) where Group A was given aerobic exercise and
Group 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 and
resistance exercise in prehypertension. Result showed significant reduction in blood pressure in both group. in aerobic group
the pre and post effect of aerobic exercise is mean=2.30,SD=1.658 since the significance value for changes in all measurement
are 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 and
post effect of resistance exercise is mean=2.50,SD=1.638 since the significance value for changes in all measurement are less
then 0.05(p=0.00) and the average difference of 2.95 per subject in resistance group. These result showed significant reduction
in BP (p˂0.05) in both aerobic and resistance group.
Conclusion: The study concluded that the aerobic exercise and resistance exercise both were effective in
prehypertension. And these results also suggest that there are no significant comparative difference between
aerobic and resistance group.
