Acute Effects of Handgrip on Blood Pressure in Hypertensive Adults

Acute Effects of Handgrip on Vascular Function and Ambulatory Blood Pressure in Hypertensive Adults: A Randomized Controlled Trial

The effect of handgrip training on blood pressure reduction has been demonstrated in several studies. However, acutely, there is still divergence regarding the effects of isometric handgrip exercise on blood pressure responses, especially when it is performed at different times of the day. It is suggested that the magnitude of blood pressure reduction after a single exercise session is able to predict long-term blood pressure behavior. Thus, understanding the effects of isometric handgrip exercise, performed at different times of the day, on blood pressure in adult hypertensive individuals acutely may help to understand the effects of this type of exercise chronically.

Inclusion Criteria:

1. diagnosis of hypertension controlled by up to three antihypertensive medications;
2. SBP levels ≤ 180 mmHg and/or DBP ≤110 mmHg;
3. no serious heart disease;
4. no upper limb musculoskeletal injury that prevents the handgrip.

Exclusion Criteria:

1. diagnosis of other cardiovascular diseases or diabetes during the study;
2. change the class and/or dose of antihypertensive medication during the study;
3. worsening of the disease (BP > 180 or use of four or more medications).
