The Relationship of ACWR and FMS With Injury Risk in Adolescent Players

August 14, 2023 updated by: Aynur Demirel, Hacettepe University

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Probability Sample

Study Population

All volunteer employees who are over the age of 15, have been playing a team sport for at least one year, have not been away from their spor for more than two weeks and meet the inclusion criteria of the study will be included.

Description

Inclusion Criteria:

  • Be over 16 years old,
  • Participating in a team sport for at least one year,
  • The players who have not stayed away from their sport for more than two weeks,

Exclusion Criteria:

  • Any history of orthopedic or neurological injury or pain that may interfere with normal training or competition during assessment,
  • Structural deformities such as scoliosis and leg length inequality,
  • Their level of activity differs from other athletes in the same sport will be excluded from the study.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Functional Movement Screen
Time Frame: baseline
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.
baseline
Acute chronic workload ratio
Time Frame: 8 weeks
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.
8 weeks
Injury
Time Frame: 8 weeks
The input will be provided by the health professionals on the team.

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 18, 2023

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
