Impact of Isometric Exercise on Systolic and Diastolic Blood Pressure Among Adults With Hypertension

Hypertension is one of the cardiovascular disorders characterized by increased blood pressure. One non-pharmacological effort to reduce increased blood pressure can be done through physical exercise. This study was to identify the effect of Isometric Exercise intervention on systolic and diastolic blood pressure in hypertensive patients. The Pre-Experimental Study became the design of this study involving 32 respondents from a population of 104 hypertensive patients through Purposive Sampling. Isometric Exercise intervention was given 4 times in 1 week with a duration of 15 minutes. Blood pressure variables were measured with a tensimeter and the data were analyzed by the Independent T-Test with α 0.05. The results showed a decrease in systolic of 5.875 mmHg (from a mean of 143.125 to 137.125) and diastolic of 3.25 mmHg (from a mean of 91.625 to 88.375). p value = 0.014 (<0.05), meaning that there was a difference in systolic and diastolic blood pressure pre and post test. Isometric exercise can increase stimulation of the sympathetic nervous system so that blood circulation becomes smooth through the mechanism of venous vasodilation causing a decrease in cardiac output and total peripheral resistance, followed by a decrease in blood pressure. Isometric Exercise intervention can be carried out as an effort to manage blood pressure in hypertension patients through a physical exercise approach.
