Interventions

Intervention: inspiratory muscle training at 80%, 60%, 40% of maximum sustained inspiratory pressure. The training intervention was performed 3 times a week over an eight week period. Each training se

All

Inclusion criteria

Inclusion criteria: Healthy, moderately trained subjects (aged 18 - 27 years, either sex). The rationale for the age range was so data could be compared to those obtained in a population of adults with cystic fibrosis.

Exclusion criteria

Exclusion criteria: Pre-existing respiratory disease

Design outcomes

Primary

Measure	Time frame
1. Lung volumes (vital capacity and total lung capacity) 2. Exercise capacity (cycle ergometry) 3. Inspiratory pressure Measurements were taken before the training intervention and then at the cessation of training (i.e., following the 8 weeks of training).	—
