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.

Conditions

Interventions

OTHER

Isomeric Hand Grip Exercises

Patients will be instructed to squeeze and sustain the dynamometer for 2 min at 30% M.V.C. The dynamometer pointer which read the scale provided visual feedback to the subjects for the maintenance of the 30% M.V.C. This procedure will be repeated twice for each training session with a 5-minute rest in between.

OTHER

Dynamic Hand Grip Exercises

Dynamic handgrip exercise was performed with both-sided, metronome-guided rhythmic hand contractions for 2min. The handgrip ring, closest to 20% of MVC, was chosen for DHE which was performed at a frequency of 30/min, acoustically indicated by a metronome beat.
