Plasma epinephrine (A) and norepinephrine (B) levels (means ± SE) during the final 30 min of day 2 exercise in 22 type 1 diabetic patients (11 men/11 women). On the previous day, patients had undergone two 120-min euglycemic clamps (anteEugly), hypoglycemic clamps (anteHypo), or euglycemic clamps with intravenous cortisol infusions at 1 μg · kg−1 · min−1 (anteCort1) or 2 μg · kg−1 · min−1 (anteCort2) on day 1. There were significantly fewer increases of epinephrine and norepinephrine during the final 30 min of exercise from basal levels in anteHypo and anteCort compared with anteEugly. *P < 0.05.
