[Assessment of the influence of puberty on changes in post exercise glycaemia after variable intensity physical effort in children and adolescents with diabetes mellitus type 1 (DM1)].

INTRODUCTION

During the pubertal period the metabolic control is getting worse in the most of patients with type 1 diabetes mellitus (DM1). The insufficient metabolic control may impact the post-exercise glycaemia and cause the acute complications of the diabetes.

AIM OF THE STUDY

was to assess the influence of puberty on changes in post exercise glycaemia after variable intensity physical effort in children and adolescents with diabetes mellitus type 1 (DM1).

MATERIAL AND METHODS

The study group consisted of 88 children with DM1, 6 to 19 years of age, mean age 13.00±2.77 (SD). The subjects were divided into three groups according to pubertal stage (29 prepubertal subjects, 33 pubertal and 26 postpubertal adolescents with DM1). Three tests of increasing intensity were performed, each lasting 20 minutes on three consecutive days. The controls were the same children with no exercise.

RESULTS

In prepubertal subjects statistically significant lower levels of glycaemia were found 3 minutes (p<0.05) and 1 hour (p<0.05) after high intensity exercise in comparison to the controls. The pubertal subjects had statistically significant lower levels of glycaemy after high (p<0.001, p<0.01, p<0.05) and moderate intensity exercise (p<0.05, p<0.05, p<0.01 respectively) in all three check points compared to controls. The postpubertal subjects were found to have statistically significant lower levels of glycaemy after moderate intensity exercise 3 minutes (p<0.01) and 1 hour (p<0.05) compared to controls and after high intensity exercises 3 minutes after the exercise (p<0.05).

CONCLUSIONS

The rate of changes in post exercise glycaemy level depended on pubertal stage. The most significant decrease in post exercise glycaemy was observed in pubertal subjects.
