Before beginning the exercise program, participants should warm up for 5-10 minutes with a leisurely walk. In this case, the participant’s mileage is 1 mile. The instrument used to measure blood pressure in this study was an aneroid sphygmomanometer, while a glucometer was used to measure blood glucose levels. Results: This study found that: Based on the Mann-Whitney test, it showed that there was a significant effect of walking exercise on decreasing systolic blood pressure (p 0.005), diastolic blood pressure (p 0.018), and reducing blood sugar (p 0.031).
