About this study

Official title: Okçuluk Sporcularında Stabilizasyonun ve Stabilizasyonla İlişkili Parametrelerin Atış Performansına Olan Etkisinin Servikal, Lumbal ve Skapular Seviyede İncelenmesi

The aim of this study was to investigate the effect of stabilization and stabilization-related parameters on shooting performance at the cervical, lumbal and scapular levels in archery athletes. A total of 40 archery athletes aged between 10 and 18, who have been professionally engaged in archery for at least 1 year were included in the study. Demographic information and musculoskeletal system evaluations of the athletes were done. Performance of the athletes via Upper Extremity Closed Kinetic Chain Stability Test, Hand Grip Strength test; presence of scapular dyskinesia was evaluated via the Lateral Scapular Slide Test. Cervical region stabilization was evaluated via Craniocervical Flexion Test, scapular level stabilization was evaluated via Scapular Muscle Endurance Test, lumbar region stabilization was evaluated via Abdominal Drawing-in Test and Sahrmann's Core Stability Test. As the parameters related to stabilization, postures via Corbin Postural Rating Scale; balances via Stork Balance Test, Upper Extremity Y Balance Test; pain was evaluated via the Shoulder Pain and Disability Index. Shooting performances were evaluated with 72 target shootings and a total of 720 points. .

Read the detailed description

Archery can be described as a comparatively static sport requiring strength and endurance of the upper body, in particular the forearm and shoulder girdle. Skill in archery is defined as the ability to shoot an arrow to a given target in a certain time span with accuracy. The discipline is described as a three-phase (the stance, the drawing and the sighting) movement. Shooting can be divided these phases into six: bow hold, drawing, full draw, aiming, release and follow-through. Each of these phases represented a stable sequence of movements and was ideal for studying the motor control and skill acquired during this voluntary kinematic process.

An archer pushes the bow with an extended arm, which is statically held in the direction of the target, while the other arm exerts a dynamic pulling of the bowstring from the beginning of the drawing phase, until the release is dynamically executed. The release phase must be well balanced and highly reproducible to achieve commendable results in a competition.

The bowstring is released when an audible impulse is received from a device called "clicker" that is used as a draw length check. Each arrow can be drawn to an exact distance and a standard release can be obtained using the device. The clicker is reputed to improve the archer's score and used by all target archers. The archer should react to the clicker as quickly as possible. In particular, a repeated contraction and relaxation strategy in the forearm and pull finger muscles should be developed for this reason.

The aim of this study was to investigate the effect of stabilization and stabilization-related parameters on shooting performance at the cervical, lumbal and scapular levels in archery athletes. A total of 40 archery athletes aged between 10 and 18, who have been professionally engaged in archery for at least 1 year were included in the study. Demographic information and musculoskeletal system evaluations of the athletes were done. Performance of the athletes via Upper Extremity Closed Kinetic Chain Stability Test, Hand Grip Strength test; presence of scapular dyskinesia was evaluated via the Lateral Scapular Slide Test. Cervical region stabilization was evaluated via Craniocervical Flexion Test, scapular level stabilization was evaluated via Scapular Muscle Endurance Test, lumbar region stabilization was evaluated via Abdominal Drawing-in Test and Sahrmann's Core Stability Test. As the parameters related to stabilization, postures via Corbin Postural Rating Scale; balances via Stork Balance Test, Upper Extremity Y Balance Test; pain was evaluated via the Shoulder Pain and Disability Index.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. cervical stabilization

    cervical stabilization assess with craniocervical flexion test.

    Measured: baseline

  2. lumbar stabilization grade

    lumbar stabilization asses with sahrmann's core stability test and will grade according to test outcome.

    Measured: baseline

  3. lumbar stabilizator muscle contraction

    the athlete perform abdominal drawing in meneuver and contraction amount record.

    Measured: baseline

  4. scapular dyskinesis type

    Kibler's scapular diskinesis test and lateral scapular slide test

    Measured: baseline

  5. scapular dyskinesis amount

    lateral scapular slide test

    Measured: baseline

  6. sportive performance

    the athlete will shoot 72 arrows to the target and tthe total points will record as score.

    Measured: baseline

Secondary outcomes (7)
  1. balance assessment

    upper extremity Y balance test

    Measured: baseline

  2. static balance assessment

    stand stork test

    Measured: baseline

  3. posture

    Corbin posture assessment

    Measured: baseline

  4. disability

    shoulder pain related disability will assess with The Shoulder Pain and Disability Index (SPADI). The SPADI has 13 items. Each item is scored on a visual analog scale (VAS) from 0 to 10, with 0 indicating no pain or no disability and 10 indicating the worst pain or disability possible. The total score ranges from 0 to 100, with higher scores indicating more pain and disability.

    Measured: baseline

  5. upper extremity performance

    upper extremity erformance assess with upper extremity closed chain stability test

    Measured: baseline

  6. hand grip strenght

    hand grip streng assess with hand dynamometer

    Measured: baseline

  7. muscle tightness

    pectoralis minor, shoulder abductor\&internal rotator and trapezious muscle tightness assess

    Measured: baseline
