Key result
Low volume, high effort resistance training significantly reduced resting systolic blood pressure by 29 mmHg and diastolic blood pressure by 10 mmHg in hypertensive patients over 12 weeks.
Why the study?
General exercise recommendations for hypertension are time consuming and may hinder adoption, prompting investigation into whether low-volume, high-effort resistance training is feasible and effective in a hospital setting.
Does low volume, high effort resistance training reduce blood pressure in sedentary hypertensive patients?

Low volume, high effort resistance training is a feasible and effective non-pharmacological strategy to significantly reduce resting blood pressure in hypertensive patients, potentially allowing for medication reduction.
Supports feasibility of minimal-dose resistance training in hypertension; hypothesis-generating and requires RCTs before practice consideration.
Physical exercise has been shown to have an important role in the prevention and treatment of arterial hypertension. However, the general exercise recommendations are time consuming, which might be detrimental to exercise adoption. Based on this, minimal doses of exercise have been suggested as an alternative approach and this report investigates the feasibility and effects of low volume and high effort resistance training for hypertensive patients in a hospital setting. This is a pilot non-randomized prospective study where 15 sedentary hypertensive patients (11 women and 4 men) performed 24 resistance training sessions over 12 weeks at a public hospital. The resistance training sessions consisted of two sets of four exercises, with a rest interval of two minutes between sets. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured 10 minutes before and 10 minutes after each training. No injuries or intercurrence were reported during the study. SBP decreased significantly when compared the first and last sessions, when the measures were performed at rest (152 ± 16 mmHg vs. 122 ± 9 mmHg vs, p<0.05), and after (137 ± 13 mmHg vs. 115 ± 5 mmHg, p<0.05) the resistance training session. Similarly, DBP also decreased significantly when the values from the last session were compared with the first session, when measured at rest (83 ± 14 mmHg vs 73 ± 9 mmHg, p<0.05). Low volume and high effort resistance training seems to be a feasible non-pharmacological strategy to help controlling blood pressure in hypertensive patients within a hospital.

Seguro et al. (2021) studied Arterial hypertension (n=15). Low volume, high effort resistance training vs. Baseline (first session) was evaluated on Resting systolic blood pressure (SBP) (29 mmHg reduction, p=<0.05). Low volume, high effort resistance training significantly reduced resting systolic blood pressure by 29 mmHg and diastolic blood pressure by 10 mmHg in hypertensive patients over 12 weeks.
