Scientists from the University of Calgary have found a link between human weight, grip strength in men, and the composition of the gut microbiota.
Research published FASEB Magazine.
Lack of exercise is associated with an increased risk of various diseases and death. Regular exercise is known to lead to metabolic adaptations, including an improvement in the composition of the gut microbiota, but specific changes are not well characterized.
Numerous bacteria in new study oscillibacter was typical for people with less weight. Increased activity in normal-weight individuals resulted in an increase in bacterial count actinobacteria And collinsella. The former is associated with lower cholesterol levels, while the latter has anti-inflammatory properties and improves gut barrier abilities.
Among non-obese men, greater muscle strength, F. prausnitzii And Faecalibacterium compared to men with low muscle strength. This dependence was not observed in women.
Scientists have found that overweight people have fewer bacteria. oscillibacter and increased the number converter. oscillibacter produces healthy metabolites such as butyrate through the fermentation of dietary fiber. growing population converter It is associated with impaired glucose metabolism and difficulties with weight loss. Scientists have also shown that even a small increase in activity in overweight people can improve the abundance and diversity of beneficial microbes in the gut.
The results of the study imply that human weight significantly influences changes in the composition of the gut microbiota caused by training.
