Average plasma glucagon (A), growth hormone (B), pancreatic polypeptide (C), and cortisol (D) 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 increments of glucagon, growth hormone, and pancreatic polypeptide during the final 30 min of exercise from basal levels in anteHypo and anteCort compared with anteEugly. *P < 0.05.
