Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Too often, injuring athlete results in a large amount of money being spent on rehabilitation. In a world of sports where the speed of recovery means a lot, ways are sought first and foremost to minimize the frequency of non-contact injuries. To prevent certain things, it is important to know the initial state, therefore, to see if certain factors at the outset indicate to us that there is a certain imbalance that can result in the injury. Since we live in a country where sports clubs are unable to spend large amounts of money on rehabilitation, it would be of great benefit to find reliable tests that can help to prevent an injury. Studies have shown that tests of balance, flexibility, and agility can help to prevent injury to football players in other countries. The same tests will be applied to Premier League footballers in Bosnia and Herzegovina and their effectiveness in assessing the degree of risk of lower limb injuries will be tested. If they prove reliable, they can become a standard in the prevention of these injuries, that is, they will help in the development of injury prevention programs, which would be of great benefit to both clubs and football players.

The study aims to determine whether dynamic balance and flexibility tests can be used as reliable predictors of lower limb injuries in football players and whether reduced agility influences the increased risk of injury.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Professional Footballers

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

Y Balance Test

Intervention Type 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.

Sit and Reach Test

Intervention Type 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

Intervention Type 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.

S_RAG (reactive agility)" Test

Intervention Type DIAGNOSTIC_TEST

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

S_CODS (change of direction speed) Test

Intervention Type 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.
