An interventional study of Nose-breathing training and Mouth-breathing training in Hypoventilation and Hyperventilation, sponsored by Universität des Saarlandes. Recruiting at 1 site in Germany. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-04-17.
Sponsored by Universität des Saarlandes · Not applicable, Interventional, and Basic science
The goal of this clinical trial is to learn if yoga-based breathing styles could improve memory performance in adult persons without relevant prior experience in yoga, meditation or similar disciplines and without existing health problems which could hinder the implementation of the breathing exercises.
The main questions it aims to answer are:
Participants will complete a memory test while doing a specific nasal and oral breathing.
They will complete a two-week training period after the test with daily nasal or mouth breathing training or no training at all, depending on the group, the are divided into.
Researchers will compare the effect of different breathing styles on memory ability among themselves.
The goal of this clinical trial is to learn about the effect of yoga-based breathing styles on the human brain regarding memory performance in adult persons without relevant prior experience in yoga, meditation or similar disciplines and without existing health problems which could hinder the performance of the breathing exercises.
The main questions it aims to answer are:
Participants will complete a memory test while performing controlled nasal and oral breathing.
They will complete a two-week training period after the test with daily nasal or mouth breathing training or no training at all, depending on the group assignment.
Researchers will compare the nasal breathing group to the mouth breathing and the comparison group to see if the nasal breathing results in a significant improvement of the memory capacity.

Controlled nose-breathing
Other: Nose-breathing training
Controlled mouth-breathing
Other: Mouth-breathing training
no intervention
13 days of controlled nose-breathing training at a specific frequency with a duration of approximately 15 min a day
13 days of controlled mouth-breathing training at a specific frequency with a duration of approximately 15 min a day
Improvement of learned images
Memory improvement by performing the home nasal breathing training. The correctness of the mapping is measured by the percentage correctness of the given answers in the memory test, which takes place promptly after the learning phase and 2 weeks later.
Time frame: 2 weeks
Reduction of subjective stress level
The subjective stress level is determined by a subjective stress statement, before and after each learning and retrieval phase, at the first appointment and at the second after 2 weeks.
Time frame: 2 weeks
Plan to share: No
Started Jun 2023 (actual). Primary completion is estimated for Jul 2024, 13 months after the start.
Of 35 non-industry interventional studies with no phase under Hypoventilation, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 26. This study's planned 13 months is below that.
Counting every sponsor, half of 35 studies reached it within 15 months; a quarter within 5 and three quarters within 26.
