Study Summary

Rehabilitation approaches introduce a stimulus to a motor system, with the goal to enhance motor function to patients. For example, exposure to brief and intermittent episodes of mild hypoxia has shown to strengthen synaptic pathways to respiratory and skeletal muscle motor neurons. In humans with spinal cord injury, exposure to intermittent hypoxia (IH) alone or in combination with rehabilitative strategies has shown enhanced motor function. Another strategy known as inspiratory threshold loading, which involves breathing against pressure threshold loads, results in improved inspiratory muscle strength. Although there is evidence supporting the use of IH alone or in combination with other rehabilitative strategies in improving motor function in humans, the impact of exposure to IH or IH with inspiratory threshold loading on inspiratory muscle function and ventilation in humans is unknown.

Primary Outcome

Maximal Inspiratory Pressure(MIP) which is a measure of inspiratory muscle strength will be measured as the MIP recorded at the mouth by a pressure manometer. Subjects will be seated upright in a comfortable chair and the nose occluded with clips. After exhaling to residual volume (RV), subjects place their lips around the mouthpiece and inspire as forcefully as possible for at least three seconds. Repeated measurements will be taken, with a 1- to 2-min rest between trials, until three measureme
