Statistical Analyses

To verify that the standard meal provided a significant glycemic response in which to test the effect of vinegar and walking, a one-factor (time) repeated measures ANOVA was used to compare blood glucose at each time point within the control trial. Effect of vinegar and walking on blood glucose response following the standard meal was compared by calculating Area Under the Curve (AUC) for both trials and analyzing with a paired t-test. Blood glucose changes between time points (0 to 30, 30 to 60, 60 to 90, 90 to 120) were compared between trials (vinegar vs. walking, vinegar vs. control, control vs. walking) using an independent-samples t-test. Furthermore, correlations were run between independent variables “walking speed” and the dependent variable “blood glucose AUC.”
