  1. Values are means ± SEM. Cecal microbiota data are shown as means ± SEM expressed as the relative abundance (%) of bacterial taxa per total bacteria (16S rRNA gene copies of microbial group/total bacteria 16S rRNA gene copies). Chow: chow control diet; HFS: high fat/high sucrose diet; F: prebiotic fibre; E: aerobic exercise. HDL: high density lipoprotein; LDL: low density lipoprotein; Chol: cholesterol. Trig: triglycerides.
