| ABSTRACT |
|
The purpose of this study was to examine differences in blood glucose response to various intensities of aerobic exercise to predict and prevent an occurrence of hypoglycemia-induced exercise in type 1 diabetes. Fifty one patients with type 1 diabetes (19 boys, 32 girls, 12.1±2.4 ys, 20.1±3.5 kg/m2, 47.7±12.4 kg) participated in this study. Subjects performed two types of exercise tests (GXT: Graded exercise test, 20 m PSRT: 20 m progressive shuttle run test) at two different intensities (80 %HRmax, 55 %HRmax). Blood was sampled before and after each exercise trial for checking a blood glucose level. As the results, in comparison of high-intensity exercise trials (GXT vs. 20 m PSRT), there was a difference in exercise time (GXT = 10.6±3.0 mins vs. 20 m PSRT = 4.7±1.4 mins, p=.035). However, both exercise tests decreased blood glucose levels immediately after exercise (p=.050, p=.017) compared to ones before exercise. The second, in comparison of glucose by various exercise intensities (15 minutes 55 %HRmax = L, 15 minutes 80 %HRmax = M, 10.6±3 minutes GXT = 100 %HRmax = H), H to L (p=.018) and M to L (p=.003) were found to show significant interaction effect. This result indicated that a glucose level was significantly lowered after M and H unlike L exercises. On the other hand, the blood glucose level of L group did not change after exercise, which resulted in the difference in the pattern to maintain the pre-exercise level. Therefore, we concluded that first, in case of H exercise (GXT and 20 m PSRT), blood glucose responses after exercise might be more sensitive to intensity of exercise than time spent in these types of exercise. Secondly, in short-time exercise at a moderate intensity (over 80 %HRmax) might be more effective in lowering a blood glucose level(3 mg/dL/min) with type 1 diabetes. |
