- Aim: Continuous glucose monitoring system (CGMS) provides detailed information on glucose fluctuations. The aim was to establish whether CGMS could be used during physical exercise and whether it detects more episodes of hypoglycaemia and hyperglycaemia than frequent blood glucose measurements. Methods: Adolescents with type 1 diabetes (12 girls and 47 boys) participated in three annual sports camps that lasted for 3-4 days and included different types of exercise: soccer, floorball + cross-country skiing and golf. During the study, blood glucose values, mean 8.7 +/- 3.3 per day, were obtained with Hemocue in parallel with the CGMS. Results: Ninety-eight per cent of the participants used the sensor at all times during the camps. Eighty-seven per cent of the sensors gave adequate signals for 24 h and 66% for 48 h. Median durations of hypoglycaemia and hyperglycaemia were 1.7 h per day and 3.8 h per day, respectively. The CGMS identified significantly more episodes of hypoglycaemia (p < 0.005) and hyperglycaemia (p < 0.005) during the day and night than frequent blood glucose tests. Conclusion: We demonstrate that, even during days that included episodic strenuous physical exercise, CGMS could provide useful information on glucose fluctuations during day and night, albeit with significant failure rates.

- Background Physical activity is a critical component in the care of diabetes. Although it offers health benefits it presents challenges. Objective To investigate differences between adolescent boys and girls with type 1 diabetes and healthy controls in terms of maximal work capacity (VO2 max) and hormonal response to physical exercise of different intensities. Subjects Twelve individuals (six boys and six girls; age 1419 yr, pubertal stage 45) with type 1 diabetes (duration, 6.3 +/- 4.4 yr; hemoglobin A1c, 63 +/- 10 mmol/mol) were compared with 12 healthy controls matched for age, sex, pubertal stage, body mass index standard deviation score, and amount of regular physical activity. Methods During consecutive days, three different workloads; maximal, endurance, and interval, were performed on an Ergometer cycle. During the tests, levels of lactate, glucose, insulin, and regulatory hormones [glucagon, cortisol, growth hormone (GH), adrenaline, and noradrenaline] were measured in blood. Subcutaneous glucose was measured continuously. Results VO2 max did not differ between the groups, diabetes 49.8 +/- 9.9 vs. control 50.7 +/- 12.0 mL/min/kg. Hormonal responses did not differ between the groups except for mean peak GH level during the interval test, diabetes 63.2 +/- 27.0 vs. control 33.8 +/- 20.9 mU/L, p
