Study population: Young healthy athletes (8-16 years-old) from sports schools, clubs, teams from the territory of the Pomeranian voivodeship, Poland.

Brief summary: The primary aim of this observational cohort study is to assess sports specialization, sports performance, history of injuries (prevalence, types, areas, duration) and quality of life in young healthy athletes aged 8-16 from Poland. Athlete profiles will be created based on the variables (explained in detailed description) examined. Furthermore, the investigators will perform one-year injury follow-up.

The main questions it aims to answer are:

* Do athletes with a specific profile (lower values in athletic performance tests, low values in quality of life) evaluated at one time point, suffer injury in the future in annual observation?
* Do athletes with high sports specialization will sustain injury in one-year follow-up?
* Does sports specialization have a relationship with sports performance tests, and quality of life?
* Does sport specialisation, training volume, geographical factor relate to injury history?
* Does sports specialisation, injury history differ between sports (individual and team sports)?
* Does value of the specific muscle (lower limb) isometric strength will be associated with the dynamic balance scores in young healthy athletes?

Detailed description: Recruited young healthy athletes (8-16 years-old) from sports schools, clubs, teams will invited to study. There will be performed assessment, which included:

* participant characteristics (age, biological age, gender, height, weight, body mass index, sports experience, training workload, sports specialization, history of injuries)
* sports performance (value of dynamic balance, isometric strength of lower limbs, functional movement patterns)
* quality of life and health assessment (EQ-5D-Y)
* geographical factor (Rural, Urban)
* Sports (Individual, Team)
* History of Injuries (Localization, Type)

One-year after meetings, there will be send questionaire and phone-call to participants and their coaches/parents in order to obtain information about injuries (location, type, time-loss, etc.).

Eligibility criteria: Inclusion Criteria:

* Healthy (without injury, pain, or symptoms)
* Participation in sports activities (minimum 6 months)
* Age of 8 to 16 years-old
* Agreement to participation from parent/guardian

Exclusion Criteria:

* pain or other symptoms related during study
* lower extremity or trunk surgery in the last 6 months
* lack of medical approval for participation in sports games
