Acute Effects of Inspiratory Muscle Exercise on Glucose Level and Glucose Variability in Patients With Type 2 Diabetes.
調査の概要
詳細な説明
High-intensity exercise of inspiratory muscle was able to reduce glucose levels in previous studies, but the mechanisms underlying this reduction remain largely unknown. The present study will investigate this phenomenon, and whether confirmed, the inspiratory muscle loading would be a new approach for lowering glucose levels and glucose variability in type 2 diabetes.
The subjects with type 2 diabetes will be recruited from the ambulatory of the Hospital de Clinicas de Porto Alegre. The patients will be randomized to inspiratory muscle exercise with a high intensity load (MIP 60%) or to exercise with a load placebo (MIP 2%), on two different days. The subjects will come in the laboratory for three days consecutively during 2 weeks. On the first day will be placed the CGMS device. On the second day will be the controlled ventilation protocol with subsequently inspiratory muscle exercise, using 2% or 60% of MIP as randomized a priori. On the third day the CGMS will be removed. Individuals who are using beta-blockers will be advised to withdraw the medication 24 hours before the protocols. During all protocols will be recorded the continuous blood pressure to assess heart rate and blood pressure variabilities, both time and frequency domains will be analyzed. Also, the calf blood flow, inspiratory pressure, end-tidal carbon dioxide and oxygen saturation will be taking.

実験的：Inspiratory muscle exercise
Patients will exercise the inspiratory muscle using a load of 60% of maximum inspiratory mouth pressure (MIP 60%).
|
For inspiratory muscle exercise patients will breathe with a high load of 60% of MIP using a respiratory frequency of 15 breaths min and a prolonged duty cycle (TI/TTOT =0.7) until task failure.
The blood flow, conductance and resistance arterial will be measured in the calf using plethysmography device.
Arterial blood pressure and heart rate will be monitored continuously at the finger on a beat-by-beat basis by biopac equipment and the glucose levels will be captured by continuous glucose monitoring system.

プラセボコンパレーター：Inspiratory muscle exercise placebo
Patients will exercise the inspiratory muscle using a load of 2% of maximum inspiratory mouth pressure (MIP 2%).
|
For inspiratory muscle exercise patients will breathe with a very low load of 2% of MIP using a respiratory frequency of 15 breaths min and a prolonged duty cycle (TI/TTOT =0.7) for 10 minute.
The blood flow, conductance and resistance arterial will be measured in the calf using plethysmography device.
Arterial blood pressure and heart rate will be monitored continuously at the finger on a beat-by-beat basis by biopac equipment and the glucose levels will be captured by using the continuous glucose monitoring system.
