Change in Shannon Index (Unitless) Primary · 8 weeks

Changes to the gut microbiome will be assessed via metagenomic sequencing, from pre- to post-intervention. The Shannon Index-a measure of microbial community diversity-will be the primary indicator for changes in gut microbiota composition, and will be assessed at baseline, and following the 4th and 8th weeks. Index values are unitless and range from 0 to 1. Lower values indicate more diversity while higher values indicate less diversity. Outcome will be reported at baseline, 4 weeks, and 8 weeks and as the change from baseline to 4 weeks and baseline to 8 weeks.

Change in Serum Short Chain Fatty Acids (SCFA) Primary · 8 weeks

Participants will undergo fasted blood draws to assess serum SCFA levels. This work will be performed using the Metabolon pipeline. Outcome is reported as the sum of the serum concentrations of acetate, propionate, and butyrate in Z-score units. We report the Week 8 means and standard errors from a linear model adjusted for the Week 0 (baseline) values. The original units are reported in ng/mL and the final results are reported as standardized z-scores in which each value subtracts the mean and the difference is divided by the standard deviation. Higher values represent higher levels of SCFA w

High-density Lipoprotein Cholesterol (HDL-C) Secondary · 8 weeks

High-density lipoprotein cholesterol (HDL-C) will be measured using standard laboratory test and report in units of mg/dl. We report the Week 8 means and standard errors from a linear model adjusted for the Week 0 (baseline) values.

Body Composition Secondary · 8 weeks

Body composition will be analyzed using bioelectrical impedance. Outcome will be reported as percent body fat. We report the Week 8 means and standard errors from a linear model adjusted for the Week 0 (baseline) values.

Cardiometabolic Risk Score (CMR) Secondary · 8 weeks

The Cardiometabolic Risk Score (CMR) is the mean Z-score across systolic blood pressure, glucose, insulin, HDL, % body fat, and triglycerides. We report the Week 8 means and standard errors from a linear model adjusted for the Week 0 (baseline) values. The final results are reported as standardized z-scores in which each value subtracts the mean and the difference is divided by the standard deviation. Higher values represent higher levels of cardiometabolic risk which is considered worse. The scale is in standard deviation units. A value of 0 = the population mean.

Sponsor's own description

The present study is a 100-participant randomized controlled 2-arm parallel trial that employs a metagenomic approach to examine how 8 weeks of supervised moderate-intensity treadmill walking exercise (MWE) for 30-45 min 3 times/week alters the gut microbiome, serum short chain fatty acids, and the cardiometabolic profile, body weight, and body composition of individuals 30-64 years old who have overweight or obesity and have prediabetes.
