Entrenamiento de handgrip isométrico de alta intensidad en adultos mayores pre-hipertensos y con diagnóstico de hipertensión arterial sistémica etapa I

Abstract

Background: Moderate isometric handgrip exercise is an effective tool in the management of systemic hypertension. Aim: To evaluate the effectiveness of a high intensity isometric handgrip exercise protocol for the reduction of blood pressure in older people with pre or stage-1 hypertension. Material and Methods: Twenty-three participants aged 73.8 +/- 6.6 years (range 61-90) completed eight weeks of high intensity isometric handgrip training 2 times per week, performing 32 contractions maintained for 5 seconds, with breaks of 5 seconds. Blood pressure (BP) was measured at baseline and at the end of the intervention. Results: Systolic blood pressure decreased from 141 +/- 11 to 127 +/- 10 mmHg (p < 0.01). The decrease in diastolic blood pressure was from 79 +/- 7 to 74 +/- 6 mmHg (p < 0.01). Conclusions: A blood pressure reduction was recorded in these participants after a period of high intensity isometric handgrip exercise.
