FIG. 1.
Plasma glucose (A) and insulin (B) concentrations (means ± SE) during day 2 euglycemic exercise studies in 22 patients (11 men/11 women) with type 1 diabetes. 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. Plasma glucose and insulin levels were comparable among the four experimental groups during basal and exercise periods.
