About this study
Official title: Personalized Recommendation System of Specific Challenges for Sport Activities: Practical Approach to Football
The goal of this clinical trial is to test and compare the effects of a tailored algorithm recommendation of sport activities concreted in challenges to improve some critical performance dimensions.
Q1: Improving participant performance is achieved by using personalized sports activity recommendation using an algorithm and tracking compliance using a decentralized application (dApp)? Q2: Are participants satisfied with the performance and simplicity of the dApp used?

Participants will be asked to do specific activities recommended by the developed recommender system. The activities to be carried out will be conditioned by the profile obtained from each participant at the beginning of the intervention. They will consist of reinforcement activities for the dimensions with the lowest scores.
Researchers will compare a experimental group and a control group to see if the dimensions assessed at the beginning of the intervention were improved.

What is being measured
The primary outcome is the main question the study is designed to answer.

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 4 inclusion and 4 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 10 Dec 2025. 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?
Score of the system usability at the end of the intervention (time frame: At the end of the intervention (8 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 10 Dec 2025.
