About this study
Official title: Effects of Blood Flow Restriction Resistance Training on Muscle Characteristics, Strength and Performance of Professional Soccer Players
The aims of this clinical study are evaluated the effects of Blood Flood Restriction training on the sport performance of professional and semi-professional soccer players. The participants are twenty male professional and semi-professional soccer players who are playing at RCD Mallorca. Participants will be assigned in two different groups. Both groups develop for six weeks a strength training programs. The first group will base their training in Low Load using Blood Flow Restriction (20-50% of one maximum repetition). The second group will base their training in High Load (60-80% of one maximum repetition). This training program includes three type of exercises in each training session; back squat, single deadlift and barbell hip thrust. Before and after this program the investigators will collect sociodemographic and anthropometrics data. On top of that, the investigators will evaluate the muscle mass, the electrical activity produced by skeletal muscles, the muscle strength and the sprint ability of every participant. Before to the evaluation, the soccer players will warm-up during 15 minutes under the control of the evaluators.

PARTICIPANTS:
Participants are soccer players of RCD Mallorca (Second Spanish Football Division) and RCD Mallorca B (Third Spanish Football Division).Before to start the study, every participant will receive an informed consent about the clinical study. This informed consent will be signed by them according to Declaration of Helsinki. At the same time, the data will be anonymized and only the main researcher of the study will have access to it, to ensure compliance with the Data Protection Law.
W-UP:
The warm-up will consist of 5 minutes running slow (treadmill), 5 minutes mobility, and 5 minutes of running exercises. In addition, the warm-up will contain a familiarization with the jump test

Questions about this trial
What is this clinical trial studying?
A study testing Blood Flow Restriction Strength training with low load and High Load Strength Training in people with Resistance Training and Blood Pressure, 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 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: finished, as of the sponsor's last update on 2 Jun 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 Muscle Mass (time frame: Change from Baseline in Muscle Mass at 6 Weeks). The study lists 7 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 2 Jun 2023.
