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.”
