Exercise is one of the first strategies used to treat obesity-related health problems like type 2 diabetes and other cardiovascular disease, but scientists don’t understand exactly how it works to improve metabolic health.<\/p>\n\n\n\n
To that end, University of Michigan researchers examined the effects of three months of exercise on people with obesity, and found that exercise can favorably modify abdominal subcutaneous adipose tissue, the fat tissue just beneath the skin, in ways that can improve metabolic health\u2014even without weight loss.<\/p>\n\n\n\n
Surprisingly, moderate and high-intensity exercise yielded the same positive changes in fat tissue composition and structure, and\u00a0fat cells\u00a0shrank a bit even without weight loss, said principal investigator Jeffrey Horowitz, U-M professor of kinesiology.<\/p>\n\n\n\n
The findings appear in\u00a0The Journal of Physiology<\/em>. Co-first authors are U-M doctoral student Cheehoon Ahn and Ben Ryan, U-M postdoctoral research fellow now at the U.S. Army Research Institute of Environmental Medicine.<\/p>\n\n\n\n
