Key result
Circuit training lowers resting systolic blood pressure by ~10 mmHg in hypertensive older women.
Why the study?
Hypertension is a primary risk factor for heart disease in the elderly, and strength training may help control blood pressure levels.
Background: Hypertension is considered a primary risk factor for heart disease in the elderly.However, strength training can help control blood pressure levels.Methods: Twenty elderly hypertensive women (73.6 ± 8.1 years, 61.6 ± 11.8 kg, 153.3 ± 5.8 cm) were recruited to participate in this study.All of them underwent resting blood pressure, anthropometric and muscle strength measurements.The training protocol was performed in a circuit (CT), with three sets of 8 to 10 repetitions with 30-second intervals between sets and 1 minute between sequences.Training was performed twice a week for twelve weeks.The exercises were performed following this sequence: leg press, bench press, knee extension, lat pulldown, plantar flexion, and triceps extension.Results: After 12 weeks of CT, significant improvements in body composition (p≤0.05),increased levels of muscle strength (p = 0.001) and reduced systolic blood pressure (p = 0.001) were observed.There were no differences in body weight, BMI, and diastolic blood pressure (p = ≥0.05). Conclusion:The CT protocol is efficient for improving physical conditioning and reducing systolic blood pressure in hypertensive older women.

Diogo Cardozo (2020) studied Hypertension (n=20). Circuit training vs. Pre-training values (self-controlled) was evaluated on Systolic blood pressure (SBP) (Mean difference -10.1 mmHg, p=0.001). 12 weeks of circuit training significantly reduced resting systolic blood pressure by a mean of 10.1 mmHg (p=0.001) in hypertensive older women.
