Non-invasive Training of the Inspiratory Muscles in Athletic Women

January 30, 2026 updated by: Rocío Abalo, University of Vigo

Pilot Study to Evaluate a Non-invasive Training System for Inspiratory Muscles in Athletic Women

The goal of this clinical trial is to study whether there are significant differences between the control and experimental groups in terms of the improvement in lung function of the athletes who have performed Inspiratory muscle training with powerbreath. The main question it aims to answer is:

• the study that power breath is effective in providing improvements in inspiratory muscle strength, lung function, exercise capacity, quality of life, analytical parameters, dyspnea, fatigue and activities of daily living and impacting their sporting success.

Researchers will compare specific powerbreath training with nettraining period without this device.

Participants will:

  • Perform regular sports training along with powerbreath training for 10 weeks
  • A washout period of two months
  • Perform regular sports training for 10 weeks

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Training routine and additionally perform Inspiratory Muscle Training 1
The experimental 1 group will follow their regular training routine and additionally perform Inspiratory Muscle Training using the PwB Medic Plus device. This training consists of 30 breaths, twice daily, with a resistance load set between 40% and 60% of their Maximum Inspiratory Pressure. The intervention will last for 10 weeks
Device: Inspiratory Muscle Training 1
Inspiratory Muscle Training using the no invasive device. This training consists of 30 breaths, twice daily, with a resistance load set between 40% and 60% of their Maximum Inspiratory Pressure. The intervention will last for 10 weeks
Experimental: Training routine and additionally perform Inspiratory Muscle Training 2
The experimental 2 group will follow their regular training routine and additionally perform Inspiratory Muscle Training using the PwB Medic Plus device. This training consists of 30 breaths, twice daily, with a resistance load set between 40% and 60% of their Maximum Inspiratory Pressure. The intervention will last for 10 weeks
Device: Inspiratory Muscle Training 2
Inspiratory Muscle Training using the no invasive device. This training consists of 30 breaths, twice daily, with a resistance load set between 40% and 60% of their Maximum Inspiratory Pressure. The intervention will last for 10 weeks
No Intervention: Normal Training routine 1
No Intervention: Normal Training routine 2
