简要总结
The effects of inspiratory muscle training (IMT) remain controversial. Many studies have examined the effect IMT has on exercise performance, but any changes to the body that come from IMT have yet to be looked at.
This study will look at how someone breathes can change after IMT. Understanding how IMT changes the body can help us use IMT in different treatments.

结局指标
主要结局
Diaphragm Electromyography
时间窗: Post Intervention - ie. immediately after 5 weeks of inspiratory muscle training
Using a multipair esophageal electrode catheter we will determine any changes to the electric activity of the diaphragm. Diaphragm electromyography (EMG) has been expressed as %max. This unit is determined as the ratio of average EMG value (uV) divided by the maximal EMG activity (uV) generated during a maximal respiratory maneuver (inspiratory capacity during exercise).
次要结局
- Accessory Respiratory Muscle Activation(Post-intervention - ie. immediately after 5 weeks of inspiratory muscle training)
