Exercise Effects on Adipose Tissue Structure and Function in Obesity and Metabolic Syndrome
This study is looking at how exercise affects fat tissue in people with obesity and metabolic conditions. Researchers want to understand how exercise improves health, especially in fat tissue, which could lead to new ways to prevent and treat insulin resistance (when your body doesn't use insulin properly) and obesity-related diseases. You would be assigned to either an exercise group or a group that doesn't exercise. All participants will go through a 10% weight loss program, followed by a high-calorie diet to regain half of the lost weight. The study is looking for 46 participants between 18 and 40 years old with a BMI between 27-45 kg/m2 who don't regularly exercise. Success will be measured by changes in glucose tolerance, fat tissue fibrosis (scarring), and muscle capillarization (blood vessel growth). The current status of the study is unclear.
- Study design
- This is an interventional study with 46 planned participants. You would be randomly assigned to one of two groups: an exercise group or a no-exercise (control) group.
- What's involved
- You would undergo a series of metabolic tests before and after a 10% weight loss program, and again after a high-calorie diet to regain half of the lost weight. If in the exercise group, you would complete moderate intensity continuous exercise 4 days/week.
- Compensation
- Not stated in the trial record.
- Follow-up
- Primary endpoints are measured at 2 hours and 30 minutes after certain tests. The overall follow-up duration is not specified.

What this trial measures
- Oral Glucose Tolerance Test (OGTT)2 hours
A test in which glucose is given and blood samples taken afterward to determine how quickly it is cleared from the blood will be completed at each clinical visit appointment..
- Adipose Tissue Fibrosis30 minutes
measured histologically using Sirus Red Staining, quantified using ImageJ software at each clinical visit appointment.
- Muscle Capillarization30 minutes
measured immunohistochemically using an antibody for CD31, quantified using ImageJ software at each clinical visit appointment.
- Adipose Capillarization30 minutes
measured immunohistochemically using an antibody for CD31, quantified using ImageJ software at each clinical visit appointment.
- Fat Cell Size3 minutes
measured histologically using Hematoxylin and eosin (H \& E) staining, quantified using ImageJ software at each clinical visit appointment.
