Abstract

Aim: Evidence suggests that the gut microbiome is involved in type 2 diabetes mellitus (T2DM). This study investigates the association between gut microbiota composition, cognitive function, and metabolic health in postmenopausal women with T2DM following a 12-week home-based multi-task exercise intervention. Methods: Seventy postmenopausal women with T2DM were randomly assigned to either an intervention group, which performed home-based multi-task exercises, or a control group. Gut microbiota, cognitive function, physical fitness, and metabolic indices were assessed before and after the intervention. Results: Exercise training significantly increased Akkermansia muciniphila and Faecalibacterium levels, and reduced Lactobacillus abundance (p < 0.05). Participants showed improvements in HDL levels, cognitive function, and physical fitness (p < 0.05). Among the microbial changes, an increased abundance of Akkermansia was significantly correlated with improvements in high-density lipoprotein (HDL) levels (r = 0.41) and cognitive function (r = 0.49). Conclusion: This study supports the potential effectiveness of multi-task exercise programs in enhancing physical fitness and metabolic health in postmenopausal women with T2DM. The findings also suggest a possible connection between the gut and the brain, with Akkermansia muciniphila emerging as a potential mediator. Investigating the Akkermansia-to-brain pathway represents a promising and emerging area of research that warrants further exploration. © 2025 Elsevier B.V., All rights reserved.
