About this study
Official title: The Relationship of Acute-Chronic Workload Ratio and Functional Movement Screen With Injury Risk in Adolescent Team Sport Players
In this study, we examine how acute to chronic workload ratio and functional movement screen scores relate to injury risk in teenage athletes who play team sports.
Read the detailed description
At least 60 volunteer athletes who have played team sport for at least 1 year, have not been away from the field for more than 2 weeks, 15 years and older are planned to include this study. All participating athletes in this study will sign an informed consent form then their demographic information will be recorded. The injury risk of athletes will be evaluated by functional movement screen. The functional movement screen is a test battery consisting of 7 tests. These tests are deep squat, hurdle step, in-line lunge, active straight-leg raise, trunk stability push-up, rotary stability and shoulder mobility. To calculate the acute-chronic workload, internal workloads during training and/or matches will be added up over a period of 8 weeks. As part of the study, health professionals on the team will provide injury information for the athletes. Sports injuries will be classified based on the type of injury (contact or non-contact) and the area of the body affected. The severity of the injury will be determined as follows: minimal (1-3 days of missed sports activity), mild (4-7 days of missed sports activity), moderate (1-4 weeks of missed sports activity), and severe (4 or more weeks of missed sports activity).

What is being measured
The primary outcome is the main question the study is designed to answer.
Functional Movement Screen
To assess the risk of injury, we will utilize the Functional Movement Screen.The FMS test scores range from 0 to 3, with 0 being the worst and 3 being the best. The highest possible score is 21. Individuals who score 14 points or lower are at a higher risk for injury, while those who score above 14 points have a lower risk of injury.
Measured: baseline
Acute chronic workload ratio
To determine an athlete's workload, we ask them to rate their training time and fatigue level using the modified Borg scale after each session. We then calculate the workload by dividing the acute workload by the chronic workload using specific formulas.
Measured: 8 weeks
Injury
The input will be provided by the health professionals on the team.
Measured: 8 weeks
