Impact of Exercise on Retinal Microvascular Regulation Measured by Dynamic Vessel Analysis in Healthy Individuals
An observational study of Healthy Middle-aged Subjects and Age Range Was 18 to 31 Years, run by University Medicine Greifswald at 1 site in Germany.
Trial summary
Objective The investigators assessed the acute impact of physical exercise on retinal vessel regulation. This might be of clinical importance if retinal vessel regulation is examined with the very sensitive method of the dynamic vessel analyzer Design Forty middle aged (age range 18 to 31 years, mean age 24 years)… Read more about this study

About this study
Objective The investigators assessed the acute impact of physical exercise on retinal vessel regulation. This might be of clinical importance if retinal vessel regulation is examined with the very sensitive method of the dynamic vessel analyzer Design Forty middle aged (age range 18 to 31 years, mean age 24 years) healthy subjects (26 female / 14 male) had retinal examinations with static and dynamic vessel analysis prior and after (0.5h, 1.5h, 2.5h) intense exercise of 20 minutes.

Questions about this trial
What is this clinical trial studying?
An observational study of Healthy Middle-aged Subjects and Age Range Was 18 to 31 Years, run by University Medicine Greifswald 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 1 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 17 Feb 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. 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?
retinal vessel diameter. 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 17 Feb 2011.
