Genetic Polymorphism Connected to Top-level SwimmersNCT01319032
Genetic Polymorphism and Israeli Top-level Swimmers' Performance and Expertise
An observational study of Genetic Polymorphism Connected to Top-level Swimmers, run by Hillel Yaffe Medical Center at 1 site in Israel.
Trial summary
In a study conducted in our laboratory few years ago, we genotyped 22 genes in 2 athletic groups (endurance and sprinters) and in age and gender matched nonathletic controls. Few of these genes were found to be associated with athletic performance and area of specificity. Read more about this study

About this study
In a study conducted in our laboratory few years ago, we genotyped 22 genes in 2 athletic groups (endurance and sprinters) and in age and gender matched nonathletic controls. Few of these genes were found to be associated with athletic performance and area of specificity. Since then a few more genes have been found that are related to athletic performance, and we intend to study various genes related to 3 genetic cascade: genes associated with body fluid balance and homeostasis, genes associated with muscle strength, and genes associated with bioenergy. The results of this study compared with athletic level will provide deeper insight into the genetic mechanisms involved in performance.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Questions about this trial
What is this clinical trial studying?
An observational study of Genetic Polymorphism Connected to Top-level Swimmers, run by Hillel Yaffe Medical Center at 1 site in Israel.
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 2 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: status not confirmed, as of the sponsor's last update on 21 Mar 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 Israel. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Sigal Ben Zaken, PhD (972-52-2209853), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Identification of genes associated with swimming performance (time frame: One year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01319032, which also lists 1 linked publication.
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 21 Mar 2011.
