Aerobic Versus Resistance Exercises on Insulin Sensitivity in Obese Patients

Early Phase 1

Active, not recruiting

• Conditions: Insulin Sensitivity/Resistance
• Interventions: Drug: Metformin

• Registration Number: NCT06772857
• Lead Sponsor: Cairo University

Brief Summary

The purpose of study is to compare the effect of different exercise modes on insulin resistance and body composition in obese patients.

Detailed Description

The global epidemic of obesity becomes a major healthy, social, and economical burden.Indeed, it has been well established that obesity directly increases cardio metabolic risk by altering the insulin sensibility. Moreover, obesity causes additional health problems as it is closely associated with the development and progression of coronary heart disease.

According to the World Health Organization (WHO), Egypt ranks 18th with the highest prevalence of obesity worldwide.( Global Obesity Levels,2020) Deaths attributable to non-communicable diseases represent about 71% of the total mortality burden .(World Health Organization,2021) Lack of exercise and sedentary behaviour (prolonged sitting) are major risk factors for insulin resistance The prevalence of obesity has increased in adults in Egypt to reach about 40% according to 100million health survey (2019) compared to the 36% estimate of 2017 STEPwise survey .

This review presents established knowledge on the effects of physical activity (PA) on whole-body insulin sensitivity (SI) and body composition .

1. Sixty obese prediabetic patients from both sexes with ages ranging from 30 to 40 years old.

2. Their body mass index will be ranged from 30 to 34.9 kg/m2.

3. They have insulin resistance assessed by the homeostasis model assessment for insulin resistance (HOMAIR) Levels above 1.9

4. Their blood glucose level will be ranged from 100 to 125 mg/dL (5.6-6.9 mmol/l)

5. They will receive the same medical and diet regimen in addition to instructions not to change their physical activity during the study.

Study group A (20 patients):will receive aerobic exercise training in addition to medical and diet regimen. This mode of exercise training will be applied 3 times/week for six weeks.

Study group B (20 patients): will receive resistance exercise training in addition to medical and diet regimen. This mode of exercise training will be applied 3 times/week for six weeks.

Control group C (20 patients): will receive medical and diet regimen only for six weeks. The patients will be instructed not to change their physical activity during the study.

Arm && Interventions

Group	Intervention	Description
Group A: Aerobic Exercise + Medical and Diet Regimen	Metformin	Study group A (20 patients) will receive aerobic exercise training in addition to a medical and diet regimen. Aerobic exercise training will be applied 3 times per week for 6 weeks. This exercise will include activities such as walking, cycling, or swimming to improve cardiovascular fitness and insulin sensitivity.
Group B: Resistance Exercise + Medical and Diet Regimen	Metformin	Study group B (20 patients) will receive resistance exercise training along with a medical and diet regimen. Resistance exercise training will be applied 3 times per week for 6 weeks, focusing on strength-building exercises to improve muscle mass and insulin sensitivity.
Group C: Medical and Diet Regimen Only	Metformin	Control group C (20 patients) will receive only a medical and diet regimen for 6 weeks. Patients in this group will be instructed not to change their physical activity during the study period.

Primary Outcome Measures

Name	Time	Method
Change in Insulin Resistance Between Different Exercise Modes in Obese Patients	3months	The change in insulin resistance will be assessed using the HOMA-IR index in obese patients after different exercise interventions (aerobic vs resistance) compared to baseline. The HOMA-IR index will be calculated based on fasting blood glucose and fasting insulin levels, which are widely accepted measures of insulin resistance.
