![]() 10–12įirst, time in different glucose ranges are useful variables to evaluate hypoglycemia and hyperglycemia occurrence, respectively, alerting the risk of extreme glycemia values in athletes with diabetes. 8 These key parameters permit the assessment of glycemic variability, 9 which is a sensitive measure of glycemic health that considers both the amplitude of the excursion and the time spent in the excursion. CGM allows for new markers to measure glucose fluctuations, such as time in different glucose ranges, coefficient of variation (CV) and mean amplitude of glycemic excursion (MAGE) among other indices. Some pumps have a system called predictive low-glucose suspend system (PLGS), allowing automatic suspension of basal insulin when sensor glucose value is predicted to reach or fall below a present low limit within 30 min. To improve glycemic control, the last decade has witnessed technological advances with continuous glucose monitors (CGM) combined with continuous subcutaneous insulin infusion (CSII). 6 However, as HbA1c represents the average glycemic levels over the last 3 months, glycemic control is not entirely expressed by this marker, 1 since it does not consider daily fluctuations. ![]() 5 In fact, people living with T1D who are not physically active have higher HbA1c values when compared with their counterparts. Glycated hemoglobin A1c (HbA1c) is commonly used to measure glycemic control 4 and is inversely correlated with minutes of PA. ![]() Consequently, analysing and enacting T1D treatment strategies can improve glycemic control. ![]() 1 Since variations in daily PA are part of everyday life for people living with T1D, which represents a demanding condition for this group, 2 understanding the relationship between these variations in blood glucose control is important. ![]() Alternatively, long periods of lower intensities of PA generally result in decreased glycemia levels associated with higher peripheral insulin sensitivity and increased risk of hypoglycemia. On the one hand, high-intensity activities can cause a greater and lasting elevation in blood glucose levels (hyperglycemia). PA alters people with T1D’s glycemic levels due to the impact on the consumption of glucose that varies depending on the activity intensity. People living with type 1 diabetes (T1D) who perform physical activity (PA) experience problems maintaining glycemic control. ![]()
