Mc. Riddell et al., Glucose ingestion matched with total carbohydrate utilization attenuates hypoglycemia during exercise in adolescents with IDDM, INT J SP NU, 9(1), 1999, pp. 24-34
There are currently no guidelines regarding the carbohydrate (CHO) dosage r
equired to prevent exercise-induced hypoglycemia in children with insulin-d
ependent diabetes mellitus (IDDM). To prevent hypoglycemia by matching gluc
ose ingestion with total-CHO utilization, 20 adolescents with IDDM attended
2 trials: control(CT; drinking water) and glucose (GT; drinking 6-8% gluco
se). Participants performed 60 min of moderate-intensity cycling 100 min af
ter insulin injection and breakfast. CT's total-CHO utilization during exer
cise was determined using indirect calorimetry. In GT, participants ingeste
d glucose in the amount equal to total CHO utilization in the CT. A total o
f 9 participants had BG <4.0 mmol/L in CT compared to 3 in GT (p<.05). In c
onclusion, glucose ingestion equal to total-CHO utilization attenuates the
drop in blood glucose and reduces the Likelihood of hypoglycemia during exe
rcise in adolescents with IDDM.
