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.
