before, during and after exercise, the body needs additional KE (carbohydrates); some people also need less insulin
How much carbohydrate should be eaten before and during exercise and how much the insulin dose should be reduced depends primarily on the following factors:
- Condition or training level of the person
- Duration and exertion of physical activity
- Insulin action during exercise
- last carbohydrate meal and last insulin dose
Sufficient insulin and carbohydrates are always required for optimum performance .
- persistent physical activity, e.g. B. hiking or cycling, can be about
- Have a “blood sugar lowering” effect (muscle bulking effect) for hours after actual physical activity
- sustained physical activity can reduce insulin sensitivity to the
- Increase into the night (i.e. possibly reduce basal insulin/basal rate at night)
- Physical activity can also short-term increase blood or tissue sugar
- increase, e.g. B. through intermittent movement, stress and excitement at competitions
- Blood or tissue sugar should always be determined before sport or swimming
- To start with, your blood or tissue sugar should be at least 150 mg/dl (8.3 mmol/l) before exercise; if the value is below this, please eat 10 g of carbohydrates
- Before swimming, the blood or tissue sugar should be at least 200 mg/dl (11.1 mmol/l); if the value is below this, please eat 10 g of carbohydrates
- If the value before the activity is below 100 mg/dl (5.5 mmol/l), 20gof carbohydrates should be eaten
Sports adaptation for beginners
Before exercise, the blood glucose level should be at least 150 mg/dl (8.3 mmol/l), otherwise eat at least 1 0 g of additional carbohydrates.
Before swimming, the blood glucose level should be at least 200 mg/dl (11.1 mmol/l), otherwise eat at least 1 0 g of additional carbohydrates.
Sport adaptation for advanced users
- Reduce or halve mealtime insulin for meals containing carbohydrates directly before exercise
- Reduce mealtime insulin after exercise to reduce blood sugar drops through the muscle bulking effect
- If necessary, reduce or halve the basal insulin before physical activity
- Reduce or halve basal insulin after exercise to reduce blood sugar drops caused by the muscle bulking effect
- For pump therapy: Reduce or halve the basal rate before physical activity (temporary basal rate)
- For pump therapy: reduce or halve the basal rate after physical activity (temporary basal rate)
- For pump therapy with AID: Activate movement mode or start sports profile
