About

We compared the effects of 8 weeks of aerobic exercise only, resistance exercise only, or a combination of both on blood pressure in overweight or obese middle-aged adults with elevated blood pressure. Participants engaged in supervised exercise sessions 3 times per week for 60 minutes each session. Outcomes were assessed at baseline and after the 8-week intervention. Extra-intervention physical activity and diet were also assessed.

Inclusion criteria

  • Systolic/diastolic blood pressure of 120-159/80-99 mm Hg
  • Non-smoking
  • Overweight or obese, with a body mass index of 25-40 kg/m2
  • Inactive--not meeting the aerobic or resistance physical activity guidelines, which means engaging in less than 150 minutes/wk of moderate intensity aerobic exercise and less than 2 days per week of resistance training over the past 3 months.

Exclusion criteria

  • Unstable coronary heart disease or decompensated heart failure
  • Severe pulmonary hypertension or aortic stenosis
  • Acute myocarditis, endocarditis, pericarditis, or aortic dissection
  • Other medical condition that is life-threatening or that can interfere or be aggravated by the exercise training such as cancer, uncontrolled diabetes, severe pain or mobility limitations.
  • Premenopausal women or postmenopausal women taking hormonal replacement therapy

69 participants in 4 patient groups

Aerobic exercise (AE)
Experimental group
Description:
Engage in supervised aerobic exercise for 60 minutes on 3 days per week for 8 weeks. Exercise is performed on a recumbent bike or treadmill at 50-80% of their heart rate reserve.
Treatment:
Behavioral: Aerobic Exercise
Resistance exercise (RE)
Experimental group
Description:
Engage in supervised resistance exercise for 60 minutes on 3 days per week for 8 weeks. Exercise consists of 3 sets of 8-12 repetitions of 12 exercises for the major muscle groups.
Treatment:
Behavioral: Resistance Exercise
Combined Resistance and Aerobic Exercise
Experimental group
Description:
Engage in supervised aerobic resistance exercise for 60 minutes on 3 days per week for 8 weeks. Exercise consists of 30 min aerobic exercise at 50-80% heart rate reserve and 30 min of resistance exercise comprising 2 sets of 8-12 repetitions of 9 exercises for the major muscle groups.
Treatment:
Behavioral: Combined aerobic and resistance exercise
No training control
No Intervention group
Description:
No exercise training. Participants will refrain from any moderate-vigorous exercise or resistance training for 8 weeks.
