Survey on the Effects of Sleep Disorders on Cardiovascular Index and Exercise Performance in Diabetic Patients

Diabetes mellitus is one of the leading causes of death in the world as a result of a defect in the secretion or function of insulin. Sometimes insomnia can be a complication of diabetes or it can be a factor in diabetes. On the other hand, impairment in sleep quality is associated with increased risk of diabetes and mortality. Some studies have also shown that sleep deprivation has different effects on athletic performance. The purpose of this study was to investigate the effect of sleep disorders on cardiovascular and exercise performance in diabetic patients.

The present study was a quasi-experimental and included 25 diabetic patients selected according to the study conditions. Tests for measuring anaerobic power (Wingate test), blood pressure, heart rate, and blood glucose levels were performed in four weeks. Data were analyzed by repeated measures of variance analysis and Bonferron's post hoc test.

Insomnia caused a significant increase in blood glucose, heart rate and anaerobic power (P<0.05), but there was no significant effect on the blood pressure (P>0.05).

Since sleep deprivation can increase the risk of complications of diabetes, improving the sleep patterns of people with diabetes should be considered.
