Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Maximal Inspiratory Force | Change following 5-6 weeks of training | Inspiratory force (mmHg) will be measured using a digital pressure gauge connected to a mouthpiece. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Blood Pressure | Change following 5-6 weeks of training | mmHG measured by FDA approved automated blood pressure cuff. |
| Resting Heart Rate | Change following 5-6 weeks of training | Beats per minute, measured using a chest worn heart rate monitor. |
| Heart Rate Variability | Change following 5-6 weeks of training | Measured using a chest worn heart rate monitor. |
| Diaphragm Thickness | Change following 5-6 weeks of training | Measured by ultrasound |
Other
| Measure | Time frame | Description |
|---|---|---|
| Handgrip strength via handgrip dynamometer | Change following 5-6 weeks of training | Strength of handgrip will be recorded as kg of force using a handgrip dynamometer. |
