Summary

The purpose of the study is to determine if inspiratory muscle training improves inspiratory muscle strength of type 2 diabetes mellitus patients with inspiratory muscle weakness.

Detailed description

In congestive heart failure patients, inspiratory muscle weakness can be reversed by developing diaphragmatic hypertrophy through inspiratory muscle training, improving functional capacity and quality of life. In type 2 diabetes mellitus patients the frequency of inspiratory muscle weakness is unknown, as well as the response to inspiratory muscle training. For this reason, the present study evaluated the inspiratory muscle strength in type 2 diabetes mellitus patients and the effect of inspiratory muscle training on inspiratory muscle strength, pulmonary function, functional capacity and autonomic modulation assessed through heart rate variability.

Conditions

• Diabetes Complications
• Inspiratory Muscle Weakness

Interventions

Type	Name	Description
BEHAVIORAL	Inspiratory muscle training	For Inspiratory muscle training (IMT)patients carried out the IMT on a daily basis for eight weeks, with duration of 30 minutes and intensity corresponding to 30% of resting PImax, with a linear pressure resistance device (Threshold®). Weekly maximum inspiratory pressure (PImax) evaluations and workload adjustments were performed. Inspiratory load was adjusted on a weekly basis to maintain 30% of the subject's PImax. Training sessions were carried out at home for both groups and supervised once a week at the hospital.
BEHAVIORAL	Inpiratory muscle training placebo	Inspiratory muscle training was carried out on the same basis as in the intervention group but with no inspiratory load.
