About this study
Official title: 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.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Assessment of scapular enduranceDiagnostic test
For the assessment of scapular endurance, participants will be instructed to bend their arms and elbows while keeping a wooden rod placed between their elbows, pull a spring dynamometer placed between thei
Prone Bridge TestDiagnostic test
For the "Prone Bridge Test," participants will be instructed to lie face down with their hands and feet shoulder-width apart and then raise their bodies off the ground by lifting themselves up on their hands, forearms, and toes. A stopwa
Side Bridge TestDiagnostic 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.
Closed Kinetic Chain Upper Extremity Stability TestDiagnostic 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.
Seated Medicine Ball Throw TestDiagnostic 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Prone Bridge Test
For the measurement of core endurance, Prone Bridge Test will be applied.For the "Prone Bridge Test," participants will be instructed to lie face down with their hands and feet shoulder-width apart and then raise their bodies off the ground by lifting themselves up on their hands, forearms, and toes. A stopwatch is started, and the test is terminated if there is any deviation from the proper position. The elapsed time is recorded in seconds.
Measured: first day, in an average of one hour
Side Bridge Test
For the measurement of core endurance, Side Bridge Test will be applied. 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.
Measured: first day, in an average of one hour
Scapular Endurance Values
For the assessment of scapular endurance, participants will be instructed to bend their arms and elbows while keeping a wooden rod placed between their elbows, pull a spring dynamometer placed between their hands without dropping the wooden rod, and maintain this position. A stopwatch will be started, and the elapsed time will be recorded in seconds.
Measured: first day, in an average of one hour
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.
