Following antecedent exercise in Arm 2, glucagon responses to stepped hypoglycemia were attenuated only at the 45 mg/dL (P = 0.002), as compared to rest (rest 55 = 85 ± 5 pg/mL, exercise 55 = 71 ± 3 pg/mL, rest 45 = 102 ± 6 pg/mL, exercise 45 = 81 ± 3 pg/mL (Fig. 5B). Here, GCG is linked to Hypoglycemia.
