Abstract:
Cardiovascular diseases remain one of the leading causes of death with hypertension being one of the major health problems in adults. The first degree relatives of essential hypertension are known to be at a higher risk for development of hypertension. These people are at the danger of developing various cardiovascular diseases and may result in untimely death if not diagnosed and treated properly. The objective of this study was to compare the effects of isotonic exercise on cardiovascular parameters among normotensive young adults with and without parental history of hypertension. 30 normotensives took part in the study of whom 10 had parental history of hypertension. Baseline blood pressure (BP) and pulse rate (PR) were measured for all the participants. They performed the Harvard step test for 3 minutes. The BP and PR were measured immediately after stopping the exercise and at 3 minutes and 5 minutes after stopping exercise. The unpaired t test was applied and p <0.05 was considered significant. The PR measured immediately after stopping exercise was significantly higher in the group with parental history (92.25±8.32) compared to the other group (84.7±8.20) which is probably indicating increased sympathetic activity.
