Metabolic control in type 1 diabetes patients practicing combat sports: at least two-year follow-up study

BACKGROUND It is well recognized that physical activity should be an integral part of the management of diabetes. It remains controversial, however, whether combat sports, often preferred by young individuals type 1 diabetes mellitus (T1DM), may be performed without high risk of metabolic decompensation. The aim of this observational study was to summarize a two-year follow-up period of five young male patients with T1DM practicing combat sports under the care of a physical-activity oriented specialist diabetes outpatient clinic. Of the five patients, three mixed martial arts and two kick-boxing competitors were included in the study. To control glucose in each patient, an individual approach was used that took into consideration the type of training, the sequence of the exercises, and the relative proportion of different forms of exercise. FINDINGS During the follow-up, glycemic control was improved and maintained in all individuals. Neither an episode of hospitalization-requiring diabetic ketoacidosis nor severe hypoglycemia occurred in these patients during the follow-up. CONCLUSIONS In conclusion, an individual approach for T1DM patients practicing combat sports may result in achieving and maintaining satisfactory glycemic control without increased risk of metabolic decompensation.
