The certainty of the evidence is limited by study limitations, inconsistency, imprecision and publication bias.
Applicability to clinical practice is good, as exercise interventions are feasible in everyday life and even a sustained reduction of a few mmHg in blood pressure is clinically and population-wise meaningful. Resistance training can be recommended as part of primary and secondary prevention of arterial hypertension. IRT and DRT may be given equal priority as second-line exercise modalities.

| Reference | Comments |
|---|---|
| «Hanssen H, Boardman H, Deiseroth A, ym. Personaliz...»1 | Adults (>18 years), with and without cardiovascular risk factors, across normal BP, high-normal BP, and hypertension categories. Exercise interventions with duration 3-52 weeks. Frequency of the training typically 3x/week. Main exclusions (meta-analyses): Focus on specific diseases (eg, type 2 diabetes or chronic kidney disease), children/adolescents only, acute exercise effects, non-randomized trials, neuromotor exercise (eg, Tai Chi, Yoga), unclear cardiovascular effects, morbidity/mortality as primary endpoint. |
| «Morita H, Abe M, Suematsu Y, ym. Resistance exerci...»2 | Intervention duration: Mean 14.1 ± 7.9 weeks (range 4 to 48 weeks). Blood pressure
measurement setting: Office, home, or ambulatory measurements. Antihypertensive medication
use: Trials with BP-lowering medication "as part of the intervention" were excluded,
but baseline medication use of participants is not summarized in the main article. |
