Interval Training and Compensation of Type 2 Diabetes

Abstract

Introduction: The constant aerobic training is traditionally considered as the best physical activity for diabetic patients. But there is existing problem with adherence (complience) of this type of exercise and toleration of the specific training intensity of exercise for such training time. The advantage of interval training is usage of higher intensity of exercise for very short time alternating with low intensity of exercise. The complex effect of this type of exercise is not mentioned in literature of type 2 diabetes too much. The aim of the study was to find the effect of interval training compound to long term participation of specific exercise program. Methods: 43 obese type 2 diabetes patients treated by diet, oral antidiabetics or insulin were randomized to 2 groups. The control group consisted of 22 patients (12 women, 10 men) with average age 67.4 ± 8.4. 21 patients in main group with average age 65.29 ± 10.67 participated in a controlled exercise program. Before and after the study, both of 2 groups had complex internal investigation including spiroergometry. Results: Fitness pa-rameters improved in this group of diabetics, maximal achieved power in W∙kg−1 increased statistically significantly p < 0.05. The level of total chole- sterol decreased statistically significantly p < 0.05; average values of LDL- cholesterol decreased about 4.9% and triglycerids about 22.4%; average value of HDL-cholesterol increased about 4.6%; fasting plasma glucose levels decreased about 10.5%. Percentage of body fat p < 0.05 and diastolic blood pressure p < 0.05 decreased based on statistics. BMI tended to decrease but WHR did not change at all. Conclusion: The physical intervention influenced statistically significantly some of the observed parameters. The interval training as a part of physical activities of diabetic patients positively intervenes in complicated system of metabolical processes.
