Brief summary

The aim of our study is to obtain data on the occurrence of injuries, their mechanisms and types among children and adolescents from a youth soccer club. In addition, in order to determine the potential risk of injury, the investigators will examine the prognostic factors on the basis of tests assessing the antropometric, anatomical, physical and fitness characteristics.

Detailed description

During the 2020/2023 seasons, participants will be obliged to report injuries to to sports physiotherapists. Supervision and data collection on injuries will be documented by experienced sports physiotherapists. Using the Injury Record Form, a standardized definition and classification of injuries in line with the International Olympic Committee Consensus describing methods for recording and reporting epidemiological data on injuries and diseases in sport (Bahr et al. 2020). In addition, the data will also come from a physiotherapeutic examination, and in the case of severe injuries (requiring specialist consultation), a medical examination (orthopedic and / or neurological) and imaging tests. Training and match exhibition (time spent by participants during training units and match games) will be recorded individually for each participant by the coaches of a given team (year). The given data (in minutes) will allow to determine the total time of sports exposure. The participant's missed training and / or competition due to an injury will also be analyzed.

Design outcomes

Primary

MeasureTime frameDescription
The incidence of sports-related injuries in youth athleticsInjury incidence rates were calculated per 1000 hours of play over the 12-month prospective follow-upInjury incidence rates were calculated per 1000 player hours (matches and training) According to a consensus statement on injury definitions and data collection procedures in soccer studies;
The incidence of recurrent sports-related injuriesRecurrent injuries incidence rates were calculated per 1000 hours of play over the 12-month prospective follow-upAccording to a consensus statement on injury definitions and data collection procedures in soccer studies;

Secondary

MeasureTime frameDescription
Injuries according to type of the injuryDescription of injuries according to the type of the injury over the 12-month prospective follow-upType of the injured structure
Muscle flexibility and range of joint motionover the 12-month prospective follow-upMuscle flexibility, range of joint mobility (degrees as measured by a goniometer)
Peak Height Velocityover the 12-month prospective follow-upPeak Height Velocity (PHV) calculated using the 'maturity offset' value (report as PHV years)
Injury severityInjury severity were calculated per days of rehabilitation over the 12-month prospective follow-upTime loss in days (days unable to train)
Counter Movement Jump, Broad Jump and Single Leg Hop for Distanceover the 12-month prospective follow-upPower of the lower limbs measured as distance in single-leg and double-leg jump tasks (record as distance in centimeters cm)
Functional Movement Screen (FMS)over the 12-month prospective follow-upThe Functional Movement Screen (FMS) is a screening tool used to identify limitations or asymmetries in movement patterns. FMS consists of 7 movement tasks (deep squat, lunges, hurdle steps, a push-up, straight-leg raises, shoulder mobility, and rotary stability). Each task will be visually assessed by an experienced physiotherapist and marked on a 4-point scale (0-3, worst-best). The total maximum score that can be obtained is 21 points.
Kinematic analysis of the single-leg movement tasksover the 12-month prospective follow-upKinematic analysis of the single-leg movement tasks (single-leg squat, single-leg landing) - 2D video analysis - record as degrees of motion of the joints
Y-Balance Testover the 12-month prospective follow-upDynamic Balance of the lower extremities (record as reach distance in centimeters cm and normalized reach distance in percentages %)
Injuries according to locationDescription of the number of injuries according to location of the injury on the body over the 12-month prospective follow-upLocation of the injury on the body
