Objective: To study the effect of isometric hand grip exercise at 20% on normotensive, treated hypertensive, and non treated hypertensive in supine position, and at 300 and 600 head up tilt. Material and Methods: After recording heart rate in supine position, isometric hand grip exercise at 20% was conducted for 2 minutes with dominant hand and heart rate was recorded for 1 minute in all subjects after end of the exercise. The same maneuver was repeated before head up tilt in supine position and during head up tilt (300 and 600) in normotensive (n=104), treated hypertensive (n=76), and non treated (n=32) hypertensive individuals. Result: Isometric hand grip exercise at 20% resulted in mild increase in heart rate which was within normal limits of heart rate in all study groups. Similarly decrease in heart rate was observed in the some of the age groups. Conclusion: Isometric hand grip exercise at 20% caused marginal increase in heart rate in all study groups which was recorded within normal physiological range with decreased sympathetic stimulation and vagal modulation caused by isometric handgrip training.
