Brief Summary

This research investigates the reliability of tests to assess injury risk. Participants will be tested at the beginning of the survey and will be monitored for over 5 months. Participants will take 4 types of tests related to dynamic balance, flexibility, and agility. Subsequently, the relationship between test results and the incidence of injury in the subjects will be analyzed. If the tests prove reliable, they will be included in standard tests to assess the risk of injury to football players.

Study Arms (1)

Professional Footballers

About 110 players (out of about 400 competing in the Premier League of Bosnia and Herzegovina) would be included in the research.

Diagnostic Test: Y Balance Test; Diagnostic Test: Sit and Reach Test; Diagnostic Test: "Maximum Legs Abduction" Test; Diagnostic Test: S_RAG (reactive agility)" Test; Diagnostic Test: S_CODS (change of direction speed) Test

Interventions

Y Balance Test DIAGNOSTIC_TEST

The footballer will place one foot on the stationary platform of the test set during the test so that the top of the sneaker does not exceed the starting line. The second foot, or the tip of the foot, will push the movable part of the platform down the measuring tube, which is marked by half-inch intervals. Any lifting of the standing leg on the heel, on the toes or loss of balance will be considered a mistake and the attempt will be repeated. Mobility will be tested through 3 trial and 3 valid measurements of the lower limbs in the anterior, posteromedial, and posterolateral directions. The arms should rest on the hips.

Professional Footballers

Sit and Reach Test DIAGNOSTIC_TEST

This test involves sitting on the floor with your legs stretched straight forward. Shoes should be removed. The feet themselves are set straight against the box. Both knees must be stretched. With the palms facing down and the palms side-by-side or side-by-side, the subject approaches the measurement line as far as possible. It is important to keep your hands in the same position level, not that one reaches further than the other. Once the subject has reached the maximum distance, hold this position for one to two seconds and record the distance.

"Maximum Legs Abduction" Test DIAGNOSTIC_TEST

Seated legs abduction is a test to assess the flexibility of the groin region. Respondent without the shoe sits with its back and head resting against the wall. As a sign, the subject extends the legs (stretches) to the maximum extent. During the test, the legs should not be bent at the knee joint.

Professional Footballers

S_RAG (reactive agility)" Test DIAGNOSTIC_TEST

The test consist of fast-moving forward, and a change of direction conditioned by visual stimuli.

Professional Footballers

S_CODS (change of direction speed) Test DIAGNOSTIC_TEST

S\_CODS (change of direction speed) is a test that allows athletes to outperform their opponents in situations where they can pre-define a movement pattern.
