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

Study Overview
=================
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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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 |
