Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The global loss of muscle mass and strength associated with aging is a cause of functional impairment and disability, particularly in the older elderly (\>80 years). Respiratory function can be severely compromised if there is a decrease of respiratory (RM) strength complicated by the presence of comorbidities and physical immobility. In this context, the need for supportive services involves the need for long-term care and consequently the institutionalization.

Previous studies have shown that the increase of RM strength has positive healthy effects, such as the increase in functional capacity, the decrease in RM fatigue, the decrease of dyspnoea and the improvement of quality of life, both in healthy people and patients. Therefore, specific RM training may be regarded as a beneficial alternative to improve RM function, and thus prevent physical and clinical deterioration in this frail population.

Study hypothesis: The inspiratory muscle training (IMT) would improve respiratory muscle strength and endurance, exercise capacity and quality of life in an elderly population, who are unable to engage in general exercise conditioning.

Study Groups

Control group

Usual care

Group Type NO_INTERVENTION

No interventions assigned to this group

Treatment group

Participants will breathe against a load ≥ 50% of their baseline MIP, after which loads will increase according to the participant's tolerance across the remaining training period, using a Borg scale rating of 4 to 6 on perceived exertion as an indicator of adequate training intensity.

Group Type EXPERIMENTAL

Threshold® Inspiratory Muscle Trainer (treatment).

Intervention Type DEVICE

Interval-based program consisting of seven cycles of 2-minutes work and 1-minute rest. The sessions will take place 3 times per week over a eight-week period for a total of 24 sessions. All participants were familiarized with the breathing exercises over a two-week familiarization period at the beginning of the protocol. The load will be adjusted at ≥ 50% of baseline MIP.
