Effects of aerobic exercise and drug therapy on blood pressure and antihypertensive drugs: a randomized controlled trial|
Maruf, FA; Akinpelu, AO & Salako, BL
Background: Although aerobic exercise has been shown to lower blood pressure (BP) in human beings, its additive BP-reducing
effect on antihypertensive drug therapy seems to have been investigated in only laboratory animals.
Objectives: This study investigated the effects of aerobic dance combined with antihypertensive drugs on BP and number
of antihypertensive drugs in individuals with hypertension.
Methods: This open label randomised-controlled trial involved new-diagnosed male and female individuals with mild-tomoderate
essential hypertension after at least four weeks of treatment. They were randomly assigned to drug therapy
(Normoretic: Hydrochlorothiazide + amiloride hydrochloride, and Amlodipine) (control: n=33) and aerobic dance combined
with drug therapy (exercise: n=30) groups. Intervention in each group lasted 12 weeks. BP was measured at baseline and
during and pos-intervention. Number of antihypertensive drugs was recorded post-intervention.
Results: There were significant reductions in SBP at some periods of the intervention in the exercise group (p=0.000 to
0.002) and control group (p=0.001 to 0.002), and significant difference in DBP at some periods of the intervention in
exercise group (p=0.000 to 0.003) and control group (p=0.000 to 0.001). SBP (p=0.066) and DBP (p=0.100) did not differ
between the two groups post-12-week intervention. The BP control rates were similar between the exercises (56.7%) and
control (35.5%) groups (p=0.075). Similarly, between-group difference in the number of drugs was not significant (p=0.511).
Conclusion: This preliminary report demonstrates the tendency of aerobic dance to enhance BP control in individuals on
two antihypertensive drugs without BP control.
