The global loss of muscle mass and strength associated with aging is a cause of functional impairment and disability, particularly in the frail elderly. Respiratory function can be severely compromised if there is a decrease of respiratory (RM) strength complicated by the presence of comorbidities and physical immobility. Previous studies have shown that the specific RM training is an effective method to increase RM strength, both in healthy people and patients. In this case, specific RM training may be regarded as a beneficial alternative to improve RM function, and thus prevent physical and clinical deterioration in this population. The hypothesis is that specific RM training would improve RM strength and endurance in the experimental groups vs. control who do not participate in RM training. Institutionalized elderly people with an inability to walk were randomly allocated to a control group, a Threshold group or a Pranayama group. Both experimental groups performed a supervised RM training, five days a week for six consecutive weeks. The maximum inspiratory and expiratory pressures (MIP and MEP) and the maximum voluntary ventilation (MVV) were assessed at four time points in each of three groups.

Change from baseline in Maximum Inspiratory Pressure (MIP) at 7 weeks
Timeframe: The groups were assessed at baseline (time zero) and at the end of the training protocol (week 7).
Change from baseline in Maximum Expiratory Pressure (MEP) at 7 weeks
Timeframe: The groups were assessed at baseline (time zero) and at the end of the training protocol (week 7).
