abnormalities in the structure and metabolic function of abdominal subcutaneous adipose tissue (asat) underlie many obesity-related health complications. although endurance exercise has been shown to improve cardiometabolic health in overweight or obese adults, the specific mechanisms by which it affects abdominal adipose tissue remain poorly understood.

recently, an article published in an international journalNature Metabolismthe previous topic is“Years of endurance exercise training remodel abdominal subcutaneous adipose tissue in adults with overweight or obesity”in the research report,scientists from the university of michigan and other institutionsthrough research, it was found thatobese people who exercise regularly appear to have healthier abdominal fat tissue, and are able to store abdominal fat more efficiently and healthily than obese individuals who do not exercise.

researcher professor jeffrey horowitz said their findings suggest that regular exercise not only helps burn calories, but also changes the structure of fat tissue, making it healthier for fat storage when weight gain occurs. in order to observe the effects of regular exercise on fat tissue over the years,the researchers compared two groups of obese adults: one group consisted of 16 individuals who exercised at least four times a week for an average of 11 years; the other group consisted of 16 individuals who had never exercised regularly and were matched to the first group for weight, fat mass and gender.

the researchers took samples of subcutaneous fat tissue from the abdomen of the two groups of participants for analysis. the results showed that the fat tissue of exercisers has different structural and biological properties, which enables them to store fat more efficiently. specifically,theseindividuals' fat tissue contains more blood vessels,mitochondriaand beneficial proteins, while interfering with metabolismcollagenlevels are lower and there are fewer cells that trigger inflammation.

people who exercise regularly may have 'healthier' belly fat

professor horowitz pointed out that compared with previous short-term training studies, this study found that individuals who exercised long-term showed more significant differences in fat tissue.increasing fat storage capacity does not mean that the total amount of fat will increase, but rather that if an individual gains weight, this extra fat will be stored in a healthier way in the subcutaneous adipose tissue rather than accumulating around or in organs such as the liver or heart.

non-alcoholic fatty liver disease is a disease caused by the accumulation of unhealthy fat and is a growing concern worldwide. the disease usually occurs in overweight or obese people. the excess fat accumulates in the liver and can lead tocirrhosisorliver cancerthe researchers emphasize that future long-term studies are needed to track people who start and stick with an exercise program for years to see changes in their fat tissue, even if those changes don't alter their overall fat levels. also needed is research into the effects of different types of exercise on modifying fat tissue.

future research will continue to explore whether there are differences in fat tissue function between exercisers and non-exercisers and whether these differences translate into health effects. these findings are expected to provide us with more information on how to improve health through lifestyle interventions.
