Muscle Endurance in Children With Cystic Fibrosis

Endurance of the flexor, extensor and lateral trunk muscles will be assessed using the McGill Trunk Endurance Tests.

Inspiratory and expiratory muscle strength will be made with a portable, electronic intra-oral pressure measuring device.

Respiratory muscle endurance testing will be measured using an inspiratory muscle training device at increasing threshold load.

Peripheral muscle endurance will be assessed by performing 30 and 60 second sit-to-stand tests.
