Hyperglycemia results from counterregulatory hormone excess with, insufficient insulin leading to excessive hepatic glucose. Production and limiting increased glucose uptake into skeletal muscle. Hyperglycemia can occur before during and after,,, Various types of exercise. If the patient feels well with negative, or minimal urine and / or, blood ketonesAnd there is a clear reason for the elevated blood, glucose level such as underdosing insulin at the, preceding meal it. Is not necessary to postpone exercise based solely on hyperglycemia. However when people, with type 1 diabetes are deprived. Of insulin for 12 - 48 h and are ketotic exercise can, worsen hyperglycemia and, Therefore ketosis.Vigorous activity should be avoided in the presence of severe hyperglycemia, and ketosis especially with known insulin. Omission.
Physical activity increases hypoglycemia risk during and immediately following exercise and again,,, 7 about - 11. H postexercise. This delayed susceptibility to hypoglycemia is referred to as the "lag effect." of, exercise (3637) and is caused by muscles replenishing glycogen stores postexercise. Hypoglycemia and fear of hypoglycemia can limit. Participation in exercise.
Strategies should be developed to prevent and treat hypoglycemia readily. Individualization is. Necessary but clinical, experience suggests that it is safest for most patients to have a blood glucose level of 100 mg / dL. (5.6 mmol / L) or higher prior to starting exercise. This may be achieved by reducing the prandial insulin dose for the meal / snack. Preceding exercise and / or increasing food intake. Some patients can avoid hypoglycemia by reducing insulin (such as by lowering. Pump basal rates) (38) or by consuming additional carbohydrates during prolonged physical activity.One study in children on pumps suggested that a reduction in overnight basal insulin the night following exercise may. Reduce the risk of delayed exercise-induced hypoglycemia (39). Frequent SMBG and / or CGM use are key to, exercising safely. As is ready access to carbohydrates.
Basic recommendations for physical activity are the same as those for all children. And, adultsIndependent of the diagnosis of diabetes: children should be encouraged to engage in at least 60 min of physical activity. Daily and adults, should be advised to perform at least 150 min / week of moderate-intensity aerobic physical activity (50 - 70%. Of maximum heart rate) or a lesser amount (60 - 75 min / week) of vigorous-intensity activity 40 41 (,).Exercise should also include resistance and flexibility training.
Individuals particularly adults should be assessed,,, For cardiovascular risk and the presence of complications that might limit exercise as discussed more fully in the ADA Standards. Of Medical Care in Diabetes (42).
- Recommendations Exercise should be a standard recommendation as it is for individuals. Without, diabetes; howeverRecommendations may need modifications due to the presence of macro - and microvascular diabetes complications. (E)
