The effect of the three trial conditions on postprandial plasma glucose levels (A); positive (5-h postprandial) glucose iAUC (B); postprandial serum insulin levels (C); and positive (5-h postprandial) iAUC (D). Data for postprandial plasma glucose and serum insulin levels represent mean ± SE. Data for glucose and insulin positive iAUC represent marginal means ± SE (adjusted for age, sex, body weight, period effects, and predrink levels). *Significantly different from uninterrupted sitting condition, P < 0.001. †Significantly different from uninterrupted sitting condition, P < 0.01.
