The Relationship Between Scapular Endurance, Core Endurance, and Functional Performance in Adolescent Tennis Players

November 29, 2024 updated by: Elif AYGUN POLAT, T.C. ORDU ÜNİVERSİTESİ

Investigation of the Relationship Between Scapular Endurance, Core Endurance, and Upper Extremity Functional Performance in Adolescent Tennis Players

This study aims to examine the relationship between scapular endurance, core endurance, and upper extremity performance in adolescent tennis players. The hypothesis of this study is that better scapular/core endurance in adolescent tennis players is associated with better upper extremity performance. Establishing this relationship will contribute to identifying the exercise training necessary to improve upper extremity performance in tennis players.

Detailed Description

Tennis is a sport characterized by coordinated, repetitive, and powerful movements along the kinetic chain. Being both overhead and rotational, achieving a good shot in tennis involves transferring high forces and energy from the lower extremities to the upper extremities through the trunk. In this context, core muscles play a crucial role in athletic performance by stabilizing the shoulder girdle, pelvis, and spine, acting as a pivot point for extremity movements. Therefore, good core strength is essential during a stroke. Additionally, as the acceleration of the ball is influenced by both maximum external and internal rotation of the shoulder, tennis players require good shoulder mobility and stability. In this regard, the scapula in the shoulder girdle provides a stable foundation for the glenohumeral mobility necessary for the shot. Both the core and scapular regions serve as pivot points for upper extremity functional activities. Therefore, this study aims to examine the relationship between scapular endurance, core endurance, and upper extremity performance in adolescent tennis players. The hypothesis of this study is that better scapular/core endurance in adolescent tennis players is associated with better upper extremity performance. Establishing this relationship will contribute to identifying the exercise training necessary to improve upper extremity performance in tennis players.

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

Diagnostic test: Side Bridge Test
For the "Side Bridge Test," participants will be asked to lie on their right side, supporting themselves on their forearm and elbow, and lift themselves off the ground. A stopwatch will be started, and the test will be terminated if there is any deviation from the position. The elapsed time will be recorded in seconds. The test will then be repeated on the left side.
Diagnostic test: Closed Kinetic Chain Upper Extremity Stability Test
For the Closed Kinetic Chain Upper Extremity Stability Test, participants will be asked to assume a push-up position on a flat surface with their hands placed on two parallel lines drawn 90 cm apart. They will then be instructed to touch one hand to the other hand's side as many times as possible within 15 seconds. The test will be repeated three times, and the average of the scores will be calculated.
Diagnostic test: Seated Medicine Ball Throw Test
For the "Seated Medicine Ball Throw Test," participants will be asked to sit on the ground with their back, shoulders, and head against the wall. Holding a 2 kg medicine ball with both hands, they will start with their elbows bent and arms at their sides, then extend their elbows to throw the ball forward as far as possible. The distance between the wall and the point where the ball lands will be recorded. The test will be performed three times, and the average will be calculated.
