Effect of Isometric Handgrip Exercises on Blood Pressure of Hypertensive Adults

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.
