简要总结
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.

研究组 & 干预措施
Aerobic exercise (AE)
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.
干预措施: Aerobic Exercise (Behavioral)
Resistance exercise (RE)
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.
干预措施: Resistance Exercise (Behavioral)
Combined Resistance and Aerobic Exercise
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.
干预措施: Combined aerobic and resistance exercise (Behavioral)
No training control
No exercise training. Participants will refrain from any moderate-vigorous exercise or resistance training for 8 weeks.
