In diabetic men, exercise training reduces basal hepatic glucose production by 22%, even when insulin sensitivity (peripheral glucose disposal) does not improve.

For diabetic men, exercise may help lower fasting blood sugar by reducing the liver's glucose output, even if it doesn't improve how muscles use insulin. This suggests exercise has hepatic benefits distinct from peripheral insulin sensitivity.
