Study summary

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 researchers measure

Primary outcomes

  1. 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.

    Time frame: baseline

  2. 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.

    Time frame: 8 weeks

  3. Injury

    The input will be provided by the health professionals on the team.

    Time frame: 8 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Aug 2023; primary completion for Jan 2024, 4 months later.

Of 35 non-industry observational studies under Athletic Injuries, half reached primary completion within 10 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 12. This study's planned 4 months is below that.

Counting every sponsor, half of 35 studies reached it within 10 months; a quarter within 3 and three quarters within 12.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 21, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
