We investigated strategies to mitigate hypoglycemic risk during and after different aerobic exercises in people with type 1 diabetes (pwT1D) using continuous subcutaneous insulin infusion. Thirty-seven pwT1D (21 adults, 16 adolescents; HbA1c = 7.5 ± 1.0%) participated in two post-absorptive (4-h post-meal) exercise sessions (60-min continuous moderate intensity [CONT] vs. intermittent [INT]). Pre-exercise basal rate reduction (BRR) was either 40% or 80%, 90 min before exercise. Post-exercise, participants undertook either a 20% BRR for 10 hours with 20% reduced dinner bolus (INS) or a 45g post-exercise carbohydrate (CHO) snack with a 50% insulin bolus, and a 30g bedtime CHO snack without bolus (snack). While a similar number of hypoglycemic events (31 vs. 28) were observed between exercise modalities, CONT led to a greater decrease in blood glucose during exercise compared to INT (-3.1 ± 2.3, CONT vs. -2.7 ± 2.2 mmol/l, INT, P = 0.005). Changes in blood glucose during exercise (-3.0 ± 2.4, 40%BRR vs. -2.8 ± 2.1 mmol/l, 80%BRR, P = 0.076) and the number of hypoglycemic events (35 vs. 24) were similar between 40% and 80%BRR. Time in hyperglycemia was lower with INS compared to snack in the first 30min after exercise, but no differences were observed for late recovery period or nighttime. Compared to INT, CONT led to greater blood glucose decline without increasing hypoglycemia risk. A larger pre-exercise BRR did not further reduce hypoglycemia risk during exercise. Post-exercise INS and snack strategies led to comparable glucose profiles in pwT1D.
