Isometric and Dynamic Handgrip Training Effects on Hypertension

Plain-language summary

Essential hypertension accounts for 13 percent of total deaths worldwide, accounting for one of the major risk factors. Hypertension (high blood pressure) is when the pressure in your blood vessels is too high (140/90 mmHg or higher). Dynamic exercises, sustained hand grip contractions elicit lower systolic blood pressure and heart rate responses. So for patients undergoing exercise therapy, low intensity isometric exercises are preferable. Significant reduction is seen in mean arterial blood pressure and systolic blood pressure in individuals conducting isometric for 8 weeks in 30%. The reduction in systolic blood pressure will be clinically significant. The main objective of this study will be to determine the effects of dynamic and isometric handgrip exercise training on cardiovascular parameters in hypertensive patients Grade 1 hypertensive patients are included as per AHA and JNC7 criteria. A sample of 100 hypertensive patients will be recruited and divided into two treatment groups; G1: dynamic exercise in hypertensive patients, and G2: isometric exercise in hypertensive patients. Outcome measure will include systolic blood pressure, diastolic blood pressure, mean arterial blood pressure and pulse pressure. Outcome measures will be assessed at baseline and 2nd and 4th weeks posttreatment.
