It is becoming evident that in many individuals, diabetes of all types can
be precipitated or exacerbated by inactivity. Exercise is a cornerstone in
diabetes management and conveys many health benefits. Different forms of ex
ercise can have varying effects on the blood sugar response, especially in
individuals using insulin. Appropriate exercise for effective management of
blood sugar levels and published clinical exercise recommendations for ind
ividuals with type 1 and type 2 diabetes include additional blood glucose m
onitoring, modified insulin doses, and supplemental carbohydrate intake. Ph
ysicians who treat exercising patients with diabetes should tailor programs
to meet individual requirements.
