An interventional study of O2 Trainer and Deep breathing in Inspiratory Muscle Training and Blood Pressure, sponsored by Sam Houston State University. Completed at 1 site in United States. Open to participants aged 18 Years to 65 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-06-05.
Sponsored by Sam Houston State University · Not applicable, Interventional, and Basic science
This study aims to investigate the effects of resistive inspiratory training using the O2 Trainer on cardiopulmonary outcomes in healthy individuals.
Exclusion Criteria:
The control group will practice deep breathing exercise 5 times per week
Other: Deep breathing
The experimental group will participate in inspiratory muscle training 5 times per week
Other: O2 Trainer
The O2 Trainer uses varying caps to limit airflow during inspiration.
Comparator/placebo for the control group
Maximal Inspiratory Force
Inspiratory force (mmHg) will be measured using a digital pressure gauge connected to a mouthpiece.
Time frame: Change following 5-6 weeks of training
Blood Pressure
mmHG measured by FDA approved automated blood pressure cuff.
Time frame: Change following 5-6 weeks of training
Resting Heart Rate
Beats per minute, measured using a chest worn heart rate monitor.
Time frame: Change following 5-6 weeks of training
Heart Rate Variability
Measured using a chest worn heart rate monitor.
Time frame: Change following 5-6 weeks of training
Diaphragm Thickness
Measured by ultrasound
Time frame: Change following 5-6 weeks of training
Handgrip strength via handgrip dynamometer
Strength of handgrip will be recorded as kg of force using a handgrip dynamometer.
Time frame: Change following 5-6 weeks of training
