Influence of Stretching on Muscle Performance
A Phase 4 study testing Stretching in people with Muscle Strength, run by Fortaleza University at 1 site in Brazil.
Trial summary
The stretching is performed within sports to improve muscle performance and prevent muscle injury. However, recent studies are contradictory with common practice. Then raised the possibility that stretching before physical activity performed can decrease the muscle performance of healthy subjects. Read more about this study

About this study
Official title: Influence of Stretching Hamstring and Quadriceps Femoral Muscles on Peak Torque and the Maximum Power of the Knee
The stretching is performed within sports to improve muscle performance and prevent muscle injury. However, recent studies are contradictory with common practice. Then raised the possibility that stretching before physical activity performed can decrease the muscle performance of healthy subjects.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
StretchingOther
Also called peak of torque, performance, isokinetic dynamometer
Participants were divided into 3 groups. The group was referred to stretching 3 weekly for 4 consecutive weeks. Group B went 4 weeks without any intervention and held only one stretch before the re-test. And the group C performed passive knee mobilization. All participants were assessed for goniometry of the knee in flexion and extension and peak torque and power on the isokinetic dynamometer.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Stretching in people with Muscle Strength, run by Fortaleza University at 1 site in Brazil.
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 7 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 28 Jul 2009. 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 Brazil. 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.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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.
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 28 Jul 2009.
