In a recent paper published in Medicine and science in sports and exercise, scientist ave found that exercise can alter the composition of bacteria in the gut!!
The scientists took blood and fecal samples of all the volunteers tested. In addition, they also tested everyone’s aerobic fitness level. The volunteers were of both genders and ranged from athletic to obese. Then they had the volunteers begin supervised workouts, during which their efforts increased over time from about 30 minutes of easy walking or cycling to about an hour of vigorous jogging or pedaling three times per week. During this period, the volunteers were asked not to change their normal diets.
After six weeks, the scientists collected samples and retested everyone, and asked the volunteers to stop exercising altogether. Six weeks later, the tests were once again repeated.
The subsequent analysis showed that the volunteers’ gut bugs had changed throughout the experiment, with some increasing in numbers and others declining. The researchers also found changes in the operations of many microbes’ genes. Some of those genes were working harder now, while others had grown silent.
Most of these changes were not shared from one person to the next. Everyone’s gut responded uniquely to exercise. They found that the greatest changes were experience by lean people compared to people who were obese. They also found that the microbiome returned its original state six weeks after all exercise was stopped!
