Effects of Inspiratory Muscle Training in Elders

Not Applicable

Completed

• Conditions: Aging; Muscular Atrophy; Sensitivity Training Groups
• Interventions: Other: Training sham; Other: Inspiratory muscle training

• Registration Number: NCT01791010
• Lead Sponsor: Universidade Federal de Pernambuco

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.

Arm && Interventions

Group	Intervention	Description
Training sham	Training sham	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.
Inspiratory muscle training	Inspiratory muscle training	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.

Primary Outcome Measures

Name	Time	Method
respiratory muscle strength	Change from Baseline Respiratory Muscle Strength at 2 months

Secondary Outcome Measures

Name	Time	Method
Diafragmatic excursion and thickness of the diaphragm in the zone of apposition by ultrasonography	Change from Baseline Diafragmatic Excursion and Thickness of the Diaphragm at 2 months	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.
