Data are means ± SE.

*

Peak value during epinephrine infusion;

P < 0.01 vs. corresponding basal value. Values representing the percent change from basal during either epinephrine or insulin infusion that share the same letter as other values in that column are not significantly different; values that do not share the same letter in a column are significantly different (P < 0.05).
