Effects of Inspiratory Muscle Training in Elders

Study Overview
=================
Brief Summary
-----------------
Aging causes anatomical and physiological changes in the respiratory system and respiratory muscle strength with decline in its maximum function. This study aimed to evaluate the effects of inspiratory muscle training on respiratory muscle strength, thickness of the diaphragm and diaphragmatic mobility in older women. The investigators' hypothesis is that inspiratory muscle training improves respiratory muscle strength, the thickness of the diaphragm and diaphragmatic mobility in older women.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Inspiratory muscle training<br>Inspiratory muscle training for 8 weeks using a device that provides a linear resistance in the inspiratory phase. 7 days a week. 8 sets of 2 minutes twice a day. Intensity was at 40% of Maximal Inspiratory Pressure. | Other: Inspiratory muscle training<br> <br> * Other names: respiratory muscle training;|
| Sham Comparator: Training sham<br>Training sham for 8 weeks using a device without provides resistance. 7 days a week. 8 sets of 2 minutes twice a day. Intensity was canceled. | Other: Training sham<br>* Conducting fake training with the aim of blind the control group<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| respiratory muscle strength |  | Change from Baseline Respiratory Muscle Strength at 2 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Diafragmatic excursion and thickness of the diaphragm in the zone of apposition by ultrasonography | Ultrasound was used to evaluate diaphragm thickness non-invasively in the zone of apposition during tidal breathing and with changes in lung volume. During respiration to total lung capacity, measurement of the diafragmatic excursion was made by ultrasonography. | Change from Baseline Diafragmatic Excursion and Thickness of the Diaphragm at 2 months |
