About this study

Official title: Effects of Moderate-Intensity Continuous Exercise Versus Brisk Interval Exercise on Cardiometabolic Parameters and Sestrin-2 Levels in Hypertensive Obese Women: A Randomized Controlled Trial

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.

Read the detailed description

Obesity is a chronic disease associated with excessive adipose tissue accumulation and a persistent low-grade inflammatory state, which contributes to the development of cardiometabolic disorders such as hypertension, insulin resistance, dyslipidemia, and cardiovascular disease. In women, the coexistence of obesity and hypertension substantially increases morbidity and negatively affects functional capacity and quality of life. Exercise training is a cornerstone of lifestyle-based management; however, the optimal characteristics of aerobic exercise prescription and its effects on emerging molecular biomarkers remain incompletely understood.

Sestrin-2 is a stress-inducible protein encoded by the SESN2 gene and has been implicated in metabolic regulation through activation of the AMP-activated protein kinase pathway and suppression of inflammatory signaling pathways, including nuclear factor kappa B. Experimental and clinical evidence suggests that Sestrin-2 may play a protective role against obesity-related inflammation and metabolic dysfunction. Nevertheless, data regarding the modulation of circulating Sestrin-2 levels in response to different aerobic exercise modalities in hypertensive obese women are limited.

This study is designed as a prospective, randomized controlled trial including hypertensive obese women who meet predefined eligibility criteria. Participants are randomly allocated to one of two supervised aerobic exercise intervention groups: moderate-intensity continuous exercise or brisk interval exercise. Both interventions are conducted for a predefined training period under standardized conditions.

Cardiopulmonary exercise testing is performed to assess cardiorespiratory fitness and physiological responses to exercise, including maximal oxygen consumption. Blood samples are collected to measure serum Sestrin-2 levels and cardiometabolic parameters. Additional assessments include lipid profile, indices of insulin resistance, anthropometric measurements, functional capacity evaluated by the six-minute walk test, and patient-reported questionnaire outcomes.

The primary outcome measures of the study are changes in serum Sestrin-2 levels and maximal oxygen consumption. Secondary outcome measures include changes in cardiometabolic risk factors, functional capacity, and anthropometric parameters. The findings of this study are expected to provide insight into exercise-induced anti-inflammatory mechanisms and to inform evidence-based aerobic exercise prescriptions for hypertensive obese women.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Serum Sestrin-2 Level

    Serum Sestrin-2 levels will be measured using enzyme-linked immunosorbent assay (ELISA).

    Blood samples will be collected 48 hours before the start of the 8-week exercise program and 48 hours after completion of the intervention in order to avoid the acute effects of exercise.

    The primary outcome is the change in Sestrin-2 levels from baseline to post-intervention.

    Measured: Baseline and end of 8-week intervention

  2. Maximal Oxygen Consumption (VO2max)

    VO2max will be assessed using cardiopulmonary exercise testing (CPET) according to standardized protocols.

    Measurements will be performed before the start of the exercise program and after completion of the 8-week intervention.

    The change in VO2max from baseline to post-intervention will be analyzed.

    Measured: Baseline and end of 8-week intervention

Secondary outcomes (9)
  1. Lipid Profile

    Fasting blood samples will be collected to assess lipid profile parameters, including total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglyceride levels.

    Standard laboratory methods will be used for biochemical analysis. Changes in lipid profile parameters from baseline to the end of the 8-week exercise intervention will be evaluated.

    Measured: Baseline and end of 8-week intervention

  2. Insulin Resistance

    Insulin resistance will be assessed using the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR).

    Fasting plasma glucose and fasting insulin levels will be measured using standard laboratory methods, and HOMA-IR will be calculated accordingly.

    The change in HOMA-IR from baseline to the end of the 8-week exercise intervention will be analyzed.

    Measured: Baseline and end of 8-week intervention

  3. Functional Capacity

    Functional exercise capacity will be assessed using the 6-minute walk test (6MWT) according to established guidelines.

    The total distance walked in six minutes will be recorded at baseline and after completion of the 8-week exercise intervention.

    The change in 6-minute walk distance from baseline to post-intervention will be analyzed.

    Measured: Baseline and end of 8-week intervention

  4. Blood Pressure

    Resting systolic and diastolic blood pressure will be measured using a validated automated sphygmomanometer according to standardized guidelines.

    Measurements will be performed after at least 5 minutes of seated rest at baseline and after completion of the 8-week exercise intervention.

    The change in systolic and diastolic blood pressure from baseline to post-intervention will be analyzed.

    Measured: Baseline and end of 8-week intervention

  5. Change in body weight

    Body weight will be measured in kilograms using a calibrated digital scale at baseline and after completion of the 8-week exercise intervention.

    The change in body weight from baseline to post-intervention will be analyzed.

    Measured: Baseline and Week 8

  6. Change in body mass index (BMI)

    Body mass index (BMI) will be calculated as weight in kilograms divided by height in meters squared (kg/m²).

    BMI will be assessed at baseline and after completion of the 8-week exercise intervention.

    The change in BMI from baseline to post-intervention will be analyzed.

    Measured: Baseline and Week 8

  7. Change in waist circumference

    Waist circumference will be measured in centimeters using a non-elastic measuring tape according to standardized procedures.

    Measurements will be performed at baseline and after completion of the 8-week exercise intervention.

    The change in waist circumference from baseline to post-intervention will be analyzed.

    Measured: Baseline and Week 8

  8. Change in International Physical Activity Questionnaire (IPAQ) score

    Physical activity levels will be assessed using the International Physical Activity Questionnaire (IPAQ).

    The IPAQ provides physical activity estimates expressed as metabolic equivalent task minutes per week (MET-min/week), with higher values indicating higher physical activity levels.

    The questionnaire will be administered at baseline and after completion of the 8-week exercise intervention.

    The change in IPAQ score from baseline to post-intervention will be analyzed.

    Measured: Baseline and Week 8

  9. Change in Hospital Anxiety and Depression Scale (HADS) scores

    Anxiety and depressive symptoms will be assessed using the Hospital Anxiety and Depression Scale (HADS).

    The HADS consists of 14 items and includes two subscales: anxiety (HADS-A) and depression (HADS-D), each scored from 0 to 21.

    Higher scores indicate greater levels of anxiety or depressive symptoms. The questionnaire will be administered at baseline and after completion of the 8-week exercise intervention.

    Changes in HADS-A and HADS-D scores from baseline to post-intervention will be analyzed.

    Measured: Baseline and Week 8
