NCT04495595

Brief Summary

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.

Outcome Measures

Primary Outcomes (5)

  • 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).

    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

    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

    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

    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.

    through study completion, an average of 1 year

Interventions

There is no intervention due to the observational, cross-sectional design of the study
