Effect of Jacobson Relaxation and Structured Exercise Protocol in Stage I Hypertension – A Randomized Clinical Trial

Context: Stage I hypertension is a prevalent condition associated with an increased risk of cardiovascular disease. Nonpharmacological interventions such as aerobic exercise and relaxation methods are essential for management. This study evaluates the comparative effectiveness of Jacobson relaxation and organized exercise programs in lowering hypertension-related markers. Aims: The aim of this study was to evaluate and compare how planned exercise regimens and Jacobson relaxation methods differently affect the blood pressure, heart rate, blood sugar, and ankle–brachial index of individuals with stage 1 hypertension. Materials and Methods: Based on specified inclusion and exclusion criteria, a total of 50 participants were selected for the study. At random, the participants were split into two equal groups: Group A followed structured aerobic exercise while Group B underwent Jacobson’s relaxation program for 4 weeks. While resting heart rate and blood pressure were assessed while seated, ankle blood pressure was measured while supine to calculate the ankle–brachial index (ABI). During a fast, blood glucose levels were also recorded. Every outcome indicator was evaluated both before and after the intervention period. Results: Group A showed significant reductions in fasting glucose (difference: 17.35 mg/dL, P < 0.001), glycated hemoglobin (HbA1c) (0.41, P < 0.001), and systolic blood pressure (SBP) ( P < 0.001). Group B improved diastolic blood pressure (DBP) at weeks 2 and 3 ( P = 0.009, P < 0.001); ABI and heart rate remained unchanged. Conclusion: The intervention significantly reduced fasting blood glucose, SBP, and HbA1c levels, especially in Group A, but had no effect on heart rate or ABI. Group B experienced significant decreases in DBP, suggesting that the benefits differed for each group.
