Decreasing systolic blood pressure with isometric muscle training: a CAT

Entrenamiento de fuerza isométrica para la disminución de la presión arterial sistólica: CAT


INTRODUCTION Hypertension is a major risk factor for cardiovascular diseases such as coronary heart disease or heart failure. One of the interventions for the management of this disorder is isometric muscle training on upper and lower limbs.

PURPOSE To prove the validity and applicability of results regarding the effectiveness of isometric training in hypertensive subjects. We also attempt to answer the following question: what is the effectiveness of isometric muscle training on the decrease of systolic blood pressure in hypertensive patients?

METHODS Critical appraisal of the systematic review and meta-analysis “Isometric exercise training for blood pressure management”.

RESULTS Isometric training reduces systolic blood pressure in normotensive and medicated hypertensive subjects, with a standardized mean difference of 6.77 mm Hg (95% confidence interval: 7.93-5.62).

CONCLUSION It is reasonable to recommend isometric muscle training with the aim of lowering systolic blood pressure, considering the impact of the results of the articles analyzed and the applicability of this type of training.
