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?, conditionsModule conditions: Sport Injury, conditions: Healthy, conditions: Injury;Sports, conditions: Quality of Life, designModule studyType: OBSERVATIONAL, designInfo observationalModel: COHORT, timePerspective: CROSS_SECTIONAL, enrollmentInfo count: 373, type: ACTUAL, armsInterventionsModule, outcomesModule primaryOutcomes measure: Number of Participants with sports injury after one-year follow-up, primaryOutcomes measure: Type, location, duration, and return to sports in participants with injury at one-year follow up, secondaryOutcomes measure: Sports Specialization, secondaryOutcomes measure: History of sports-related injuries, secondaryOutcomes measure: Health-related quality of life: EQ-5D-Y, secondaryOutcomes measure: Y-Balance Test - dynamic balance test, secondaryOutcomes measure: Functional Movement Screen (FMS), secondaryOutcomes measure: Hand-Held Dynamometer (HHD) measurement - Isometric Strength of the lower extremities muscle, otherOutcomes measure: Sport workload (hours per trainings or competition), otherOutcomes measure: Peak Height Velocity, otherOutcomes measure: Sports discipline and position, otherOutcomes measure: Participants characteristics - Body Mass Index, otherOutcomes measure: Sports experience, eligibilityModule sex: ALL, minimumAge: 8 Years, maximumAge: 16 Years, stdAges: CHILD, contactsLocationsModule locations facility: Department of Immunobiology and Environment Microbiology, Medical University of Gdańsk, city: Gdańsk, zip: 80-211, country: Poland, geoPoint lat: 54.35205, lon: 18.64637, documentSection largeDocumentModule largeDocs typeAbbrev: ICF, hasProtocol: False, hasSap: False, hasIcf: True, label: Informed Consent Form, date: 2023-01-15, uploadDate: 2024-04-22T03:58, filename: ICF_000.pdf, size: 183809, hasResults: False
