Exercise Effects on Cardiometabolic Health and Sestrin-2 in Hypertensive Obese Women

Plain-language summary

Obesity is a chronic and complex disease characterized by excessive fat accumulation that adversely affects health and quality of life. It is commonly accompanied by low-grade chronic systemic inflammation, which contributes to the development of insulin resistance, type 2 diabetes, dyslipidemia, hypertension, and cardiovascular diseases. Hypertension is highly prevalent among individuals with obesity, and excess body weight is a major contributor to elevated blood pressure and related cardiometabolic risk. Regular aerobic exercise is a cornerstone of non-pharmacological management for both obesity and hypertension and has been shown to reduce chronic inflammation by downregulating pro-inflammatory pathways and upregulating anti-inflammatory mechanisms. Sestrin-2, a stress-responsive protein encoded by the SESN2 gene, has been proposed as an important regulator of metabolic homeostasis and inflammation through activation of the AMPK pathway and inhibition of NF-κB signaling. However, evidence regarding the effects of different exercise modalities on circulating Sestrin-2 levels in hypertensive obese individuals remains limited. This prospective, randomized controlled trial aims to compare the effects of two different aerobic exercise protocols on serum Sestrin-2 levels, inflammatory status, and cardiometabolic parameters in hypertensive obese women. Cardiopulmonary exercise testing will be used to comprehensively assess cardiorespiratory fitness and physiological responses to exercise. The results of this study are expected to contribute to a better understanding of exercise-induced anti-inflammatory mechanisms and to support the development of safe, effective, and applicable exercise prescriptions for hypertensive obese women.
