About this study
The project consists of a cross-sectional study in which anthropometric variables, general and specific performance variables of volleyball will be measured, and the biological maturity stage will be calculated. The main objective is to establish a relationship between the biological maturation state, the anthropometric characteristics and the performance in physical fitness tests in volleyball players between 12 and 15 years of age. To do this, there will be all the clubs in the Region of Murcia that have federated teams in these categories.

What is being measured
The primary outcome is the main question the study is designed to answer.
Volleyball performance
Qualitative assessement of the individual sport performance, taking on account the team position on the league and the role of the player in the team. The instrument used to assess this variable will be a questionnaire and the result will be expressed in points (1 to 5 points).
Measured: through study completion, an average of 1 year
Biological maturation
Calculated with anthropometric variables. The result obtained indicates the time left to the growth peak or the time that has passed from the growth peak
Measured: through study completion, an average of 1 year
Muscle mass
Muscle mass will be assessed with the corresponding formulas. The result will be expressed in kilograms
Measured: through study completion, an average of 1 year
Fat mass
Fat mass will be assessed with the corresponding formulas. The result will be expressed in kilograms
Measured: through study completion, an average of 1 year
Bone mass
Bone mass will be assessed with the corresponding formulas. The result will be expressed in kilograms.

Questions about this trial
What is this clinical trial studying?
An observational study of Development, Adolescent and Body Weight Changes, run by Universidad Católica San Antonio de Murcia 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 3 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 20 Jul 2021. 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?
Volleyball performance (time frame: through study completion, an average of 1 year). The study lists 5 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 20 Jul 2021.
