University of Michigan research team “Improves metabolic health by changing adipose tissue”
Although there are many cases where the weight does not decrease even with exercise, it has been shown that exercise changes the fat tissue of the stomach, which is a great help to health.
This is the result of a physiological analysis of the effects of exercise in 36 obese adults by a research team at the University of Michigan in the United States. The research team placed 17 participants in a moderate-intensity ‘continuous training’ group and 19 participants in a high-intensity ‘interval training (interval training)’ group, respectively, and had them exercise 4 days a week for 12 weeks.
In this study, moderate-intensity continuous training was performed for 45 minutes within the range of 70% of the maximum heart rate, and high-intensity interval training was performed 10 times for 1 minute within the range of 90% of the maximum heart rate (low-intensity activity of 60 seconds in the middle). (Securing time to recover) was defined as exercise. The researchers took blood samples from the participants and biopsies from abdominal fat on the last day of 12 weeks and three days later. Between the collection of these samples, the participants did not exercise at all.
As a result of the study, structural changes were found in the abdominal adipose tissue of participants in both exercise groups. Adipocytes became smaller in size, collagen types increased, capillary density increased, and the proteins that regulate body fat remodeling became health-favorable. This is a clear indication of beneficial changes in health.
Exercise is a key strategy used in the treatment of obesity-related conditions, such as type 2 diabetes and cardiovascular disease, but it is often not understood exactly how exercise improves metabolic health. That is why the research team entered the physiological analysis of exercise effects.
Professor Jeffrey Horowitz (kinesiology) at the University of Michigan, the study’s corresponding author, said, “It has been shown that both moderate-intensity and high-intensity exercise produced the same positive changes in the composition and structure of adipose tissue, and contracted fat cells without losing weight.” . “When you stop exercising, the structural changes go away soon,” he emphasized.
The research team said that high-intensity interval training (HIIT) is a hard exercise, but it is an exercise that people who do not have time to pay attention to. Chihoon Ahn, a doctoral student at the University of Michigan, and Ben Ryan, a postdoctoral researcher, (Ph.
The results of this study (Exercise training remodels subcutaneous adipose tissue in adults with obesity even without weight loss) were published in the ≪Journal of Physiology≫ and introduced by the American health and medical media ‘MedicalXpress’.
