Effect of Isometric Handgrip Exercises on Blood Pressure of Hypertensive Adults

Not Applicable

Completed

• Conditions: Hypertension

• Registration Number: NCT05240144
• Lead Sponsor: Riphah International University

Brief Summary

This study is designed to determine the effects of isometric handgrip exercises as compared to aerobic exercises in the hypertensive population, specifically in pre-hypertensives and those with hypertension stage I who are not taking pharmacological treatment. This exercise is designed as part of lifestyle modification for these patients and if proven effective, it can provide an easier to perform exercise regimen as an alternative to be incorporated in the exercise plan of patients who have difficulty in performing aerobic exercises because of musculoskeletal concerns.

Detailed Description

Hypertension (HTN) is a significant public health problem, with an increasing worldwide prevalence. The disease has an impact on reducing the quality of life (QOL) and can be life-threatening if not treated early. It is considered the major risk factor for cardiovascular and renal diseases. Complications of hypertension can lead to a variety of serious diseases like stroke, heart attack, and even cardiac and renal failure. Non-pharmacological management via lifestyle modification is focused in the initial stages of HTN through the reduction in alcohol consumption, cessation of tobacco smoking, maintenance of body weight, improvements in nutrition, and increases in physical activity. Physical activity improves health status and prevents the complications of hypertension like stroke and heart failure.

Typically, aerobic exercises in the form of walking and jogging are advised as part of lifestyle modification. effectiveness of resistance training is also worked upon. A relatively newer approach in the form of Isometric Hand Grip exercises (IHG) is also under research because it can serve as a useful alternative for patients who cannot perform aerobic exercises because of musculoskeletal conditions. This study is targeted to assess the effects of IHG exercises, aerobic training, both aerobic and IHG training as well as sham IHG treatment for a comprehensive assessment of effects of IHG training.

Primary Outcome Measures

Name	Time	Method
Systolic blood pressure	6 weeks	Pressure exerted by flowing blood on walls of blood vessels during contraction of heart.
Mean arterial pressure (MAP)	6 weeks	Mean arterial pressure (MAP) is the average of arterial pressure during one cardiac cycle and it will be calculated by using the formula MAP = DBP+ 1/3 (SBP-DBP).
Diastolic blood pressure	6 weeks	Pressure exerted by flowing blood on walls of blood vessels during relaxation of heart.
