About this study
The purpose of this study is to determine weather well trained athletes benefit from inspiratory (respiratory) muscle training.
Read the detailed description
- Subject: The investigators intend to include 40 well trained runners, 18 years or older.
- Design: Following lung function and exercise testing (incremental treadmill test to exhaustion, 5000m run time trial) participants will be randomly assigned to a verum or a control group. The verum group will train with a hand-held, commercially available pressure threshold loading device (POWERbreathe,UK). The control group will perform a sham-training with the same device. After six to eight weeks the the initial tests will be repeated.
- Hypothesis: Inspiratory muscle training enhances performance on submaximal work loads and in the 5000m run time trial by changes in breathing pattern. Maximum oxygen uptake remains unchanged.
- Conditions

- Respiratory muscle training, Sham training

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Respiratory muscle trainingBehavioural
Daily training with a handheld device (Pressure threshold loading). 1x50 breaths with adjustments (gradually increasing levels).
Sham trainingBehavioural
Sham training with same handheld device. 50 breaths daily on the lowest level
| Study group | Role | What they receive |
|---|---|---|
| Training | Active comparator | respiratory muscle training (pressure threshold loading) Receives: Behavioral: Respiratory muscle training |

Questions about this trial
What is this clinical trial studying?
A study testing Respiratory muscle training in people with Running Endurance, run by Universität des Saarlandes at 1 site in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 5 Jan 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
performance in the 500m run time trial (time frame: 6-8 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jan 2011; AzTrials last refreshed its copy on 6 Nov 2026.
