Researchers who made a presentation at the July conference of the Society for the Study of Ingestive Behavior, held in the United States, suggested that physical activity normalizes body weight by affecting the level of hormones released before and after meals, Internet Edition for girls and women from 14 to 35 years old Pannochka. Net Earlier studies have shown that active exercise, such as running, increases the body's sensitivity to leptin, a hormone that is secreted by fat cells and suppresses appetite.

According to scientists from the Johns Hopkins University in Baltimore in the current study, they were able to shed light on previously unknown mechanisms that might make physical exercise an effective means of controlling body weight.

In experiments on rats, scientists monitored the level of intestinal hormones released on an empty stomach and after the reception of delicious food, as well as before and after classes on the running wheel.

In rats running in the wheel, there was a higher level of amylin, the hormone that suppresses the appetite.

After eating in the blood of the same rats, a sharper decrease in the level of the appetite-stimulating hormone ghrelin, which is secreted by the stomach and pancreas. The level of ghrelin usually rises before eating and decreases after eating.

The introduction of the hormone cholecystokinin, which reduces appetite, had a more positive effect on runaway rats than on rats that did not exercise.

According to Dr. Nu-Chu Liang, one of the authors of the study, the results suggest that exercise can help control body weight by affecting the level of hormone release during meals. It is also possible the effect of physical exertion on the sensitivity of the organism to signals coming from these intestinal hormones.
