About this study
Official title: Effects of Blood Flow Restriction on Post-competition Recovery on Semi-professional and Youth Soccer Players
The objective is to evaluate the effects of blood flow restriction training on the post-competition recovery of professional and semi-professional soccer players. Randomized crossover clinical trial, with two intervention groups: Experimental group I will carry out a recovery training based on the use of the blood flow restriction (BFR) on day 1 post-competition. On the other hand, the Experimental II group will perform the same recovery training without the use of BFR. After 1 month the groups will cross their intervention and make the recovery with the opposite method to the initial one. The study will be carried out during the 2021-2022 season, from first regional to third division of Spanish soccer, with soccer teams from the Mallorca Island. Before the competition, the countermovement jump (CMJ) will be evaluated and repeated at 0, 24, and 72 h after the competition. The levels of muscle soreness (DOMS) will be evaluated pre-post-competition 0, 24, 48 and 72h later. The same procedure will be carried out to evaluate muscle fatigue, sleep quality, and stress through a questionnaire that athletes will fill out pre, 0, 24, 48 and 72h after the game. Sociodemographic and anthropometric data will be collected before starting the study.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Blood flow restriction recoveryDevice
Soccer players included in experimental group I will carry out this program for 1 week setting the blood pressure to ~ 60% of limb occlusion pressure (LOP). After a month they will carry out the program without restriction of blood flow. Which will consist of a warm-up part with continuous running (5 min), 6 sprints from box to box of the field at 60-70% of a maximum repetition, and an activation part in the form of rounds with the ball.
Active recoveryOther
Soccer players included in experimental group II will carry out this program for 1 week. After a month they will carry out the program with blood flow restriction. Which will consist of a warm-up part with continuous running (5 min), 6 sprints from box to box of the field at 60-70% of a maximum repetition, and an activation part in the form of rounds with the ball.

Questions about this trial
What is this clinical trial studying?
A study testing Blood flow restriction recovery and Active recovery in people with Resistance Training and Recovery, run by University of the Balearic Islands 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 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.

The record says: finished, as of the sponsor's last update on 3 Apr 2023. 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?
Change from Baseline in Countermovement Jump (CMJ) (time frame: Change from Baseline in countermovement Jump (CMJ Test) at 0 hours, 24 hours, 72 hours and 4 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 3 Apr 2023.
