Influence of the Biological Maturation on the Antrhopometric Variables and Sport Performance in Volleyball Players

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.

Primary outcomes

  1. Volleyball performance

    Time frame: through study completion, an average of 1 year

    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).

  2. Biological maturation

    Time frame: through study completion, an average of 1 year

    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

  3. Muscle mass

    Time frame: through study completion, an average of 1 year

    Muscle mass will be assessed with the corresponding formulas. The result will be expressed in kilograms

  4. Fat mass

    Time frame: through study completion, an average of 1 year

    Fat mass will be assessed with the corresponding formulas. The result will be expressed in kilograms

  5. Bone mass

    Time frame: through study completion, an average of 1 year

    Bone mass will be assessed with the corresponding formulas. The result will be expressed in kilograms.
