Summary

International recommendations advocate dynamic or isometric strength training as an adjunct to aerobic exercise. Due to a lack of consensus, this research addresses the acute effects of isometric exercises by handgrip or lower limb isometry as a hypotensive strategy in hypertensive adults.

Detailed description

This study is characterized as a randomized, controlled and blinded clinical trial for the evaluators and carried out integrally in the Laboratory of Clinical Investigation (LIC) of the Cardiology Institute of Rio Grande do Sul / University Foundation of Cardiology (ICFUC). The project follows all recommendations proposed by the CONSORT Statement. The study will consist of individuals of both genders, aged between 40 and 70 years who have blood pressure above 120mmhg by 80mhg. The participants, after signing the informed consent, answered a questionnaire that will evaluate the habitual level of physical activity and will be submitted to isometric exercises of palmar grip or quadriceps muscle. Pre- and post-exercise blood pressure will be monitored through the ambulatory blood pressure monitoring (ABPM) method.

Conditions

• Arterial Hypertension

Interventions

Type	Name	Description
OTHER	isometric handgrip exercise	Isometric session with handgrip: 4 sets of 2 minutes of contractions sustained at 30% of CVM, for each arm. The time between sets and between arms will be 1 minute rest.
OTHER	isometric of the lower limbs	Isometric session for lower limbs: 4 sets with 2 minutes of contractions sustained at 30% of 1RM. The rest interval will be 1 minute rest.
