Introduction: Aging is associated with changes in glucose metabolism, with increased fasting glucose, whose progressive effects may lead to glucose intolerance and type 2 diabetes. Senescence is also accompanied by changes in sleep parameters including fragmentation and increased abnormal respiratory events (apneas / obstructive and central hypopneas) with nocturnal hypoxemia that may impair glucose metabolism and insulin. Physical activity plays an important role in increasing insulin sensitivity and quality of sleep. In resemblance to the physical activity, the respiratory muscles training has been shown to increase sensitivity to insulin, but its effects on sleep parameters has not been studied yet.Objective: Investigate the influence of inspiratory muscles training on fasting hyperglycemia and sleep parameters in elderly. Methodology: The study involved the participation of 38 elderly volunteers, aged between 60 to 85 years of both genders, with increased fasting glucose (100-125 mg / dl) and sleep disorders confirmed by polysomnography. In this study the Threshold®, a device used for inspiratory muscles training was used. Participants were randomized into two groups: control group (Threshold® unloaded) and experimental group (Threshold® loaded). The research lasted for eight weeks and the exercises were applied 7 times per week, lasting 60 minutes each session. Results: There was a decrease in blood glucose levels in the experimental group (p: 0.001), the arousal index (p: 0.002) and the apnea / hypopnea index (p: 0.001), suggesting that inspiratory muscle training induces improvement of hyperglycemia fasting as well as of the sleep apnea and sleep fragmentation.
