About this study
Athelts that meet the inclusion criteria will be randomized into two groups. The experimental group will receive an 8-week (3 days per week) specificl protocol based on hamstring strengthening (isometric, concentric and excentric exercises), and the control group will not receive any additional exercise. The aim of the study is to investigate the changes in hip and knee muscle strength, in the extensibility of cuadriceps, hamstrings and hip abductors, in the physical functions and in the final marks.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Athelts that meet the inclusion criteria will be randomized into two groups. The experimental group will receive an 8-week (3 days per week) specificl protocol based on hamstring strengthening (isometric, concentric and excentric exercises), and the control group will not receive any additional exercise. The aim of the study is to investigate the changes in hip and knee muscle strength, in the extensibility of cuadriceps, hamstrings and hip abductors, in the physical functions and in the final marks.

Questions about this trial
What is this clinical trial studying?
A study testing hamstring strengthening in people with Exercise and Hamstring Injury, run by Universidad de Zaragoza at 1 site in Spain.
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 3 inclusion and 5 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 26 May 2020. 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 Spain. 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?
muscle strength (time frame: Baseline). The study lists 4 primary outcomes in all. 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 26 May 2020.
