Brief Summary

The aim of this study is to comprehensively investigate the effects of the Thrower's Ten exercise program-commonly recommended to enhance shoulder stability and strength in athletes-when applied using an external focus of attention approach (i.e., directing attention toward an object or movement outside the body), on functional performance, shoulder stability, balance, and throwing performance in adolescent basketball players. This study has been designed to examine the effects of performing the Thrower's Ten exercises with an external focus of attention on functional performance, shoulder stability, balance, and throwing performance in adolescent basketball players. Athletes will be randomly assigned to two groups: the experimental group will perform the exercises using an external focus of attention, whereas the control group will perform the same exercises without any specific attentional focus. The methods employed in this study are expected to effectively address the research objectives. The data collection tools and analytical techniques to be used are based on validated and widely accepted tests in the literature. Functional performance will be assessed using the Closed Kinetic Chain Upper Extremity Stability Test, balance will be evaluated using the Upper Extremity Y Balance Test, and throwing performance will be measured using the Medicine Ball Throw Test.

Outcome Measures

Primary Outcomes (1)

• Balance

  The Upper Extremity Y Balance Test (UEYBT) will be used to assess shoulder stability and dynamic balance. Participants will perform reach movements in three directions (anterior, posterolateral, and posteromedial), and the reach distance will be recorded. Three trials will be performed for each direction, and the maximum reach distance will be used for analysis. The UEYBT will be conducted for both the dominant and non-dominant upper extremities. Participants will begin the test in a push-up (plank) position. In this position, one hand will be placed at the center of the Y Balance Test apparatus, while both feet will remain in contact with the ground, positioned shoulder-width apart. While maintaining this position, participants will reach maximally in three directions (medial, superolateral, and inferolateral) with the contralateral upper extremity (15). After each reach, participants will return to the starting position without compromising the push-up posture.

  Assessments will be conducted before the intervention (exercise program) and after the completion of the program. The exercise program will be implemented over a period of 6 weeks. Accordingly, evaluations will be performed at baseline (pre-intervention)

Secondary Outcomes (2)

• Functional performance

  Assessments will be conducted before the intervention (exercise program) and after the completion of the program. The exercise program will be implemented over a period of 6 weeks. Accordingly, evaluations will be performed at baseline (pre-intervention)

• Shooting Performance

  Assessments will be conducted before the intervention (exercise program) and after the completion of the program. The exercise program will be implemented over a period of 6 weeks. Accordingly, evaluations will be performed at baseline (pre-intervention)

EXPERIMENTAL

This program has been designed to improve shoulder stability, muscular strength, and overall performance. The exercise protocol to be implemented consists of the Thrower's Ten Exercise Program. Thrower's Ten Exercise Program: The Thrower's Ten Exercise Program, originally developed by Kevin E. Wilk and colleagues (1993), comprising ten different exercises, will be applied to both the experimental and control groups. The exercises included in this program are as follows: 1.a. Diagonal Pattern D2 Extension 1. b. Diagonal Pattern D2 Flexion 2. a. External Rotation at 0° Abduction 2.b. Internal Rotation at 0° Abduction 2.c. External Rotation at 90° Abduction 2.d. Internal Rotation at 90° Abduction 3. Shoulder Abduction at 90° 4. Scaption (Scapular Plane Elevation) with External Rotation 5. Side-Lying External Rotation 6.a. Prone Horizontal Abduction (Neutral) 6.b. Prone Horizontal Abduction (Full Range of Motion, 100° Abduction) 6.c. Prone Rowing 6.d. Prone Rowing with External Rotation 7

ACTIVE COMPARATOR

The Thrower's Ten exercises will be performed using a neutral attentional focus approach.

Other: Exercise with neutral attentional focus

Interventions

Exercise OTHER

The exercise protocol to be implemented consists of the Thrower's Ten Exercise Program. Thrower's Ten Exercise Program: The Thrower's Ten Exercise Program, originally developed by Kevin E. Wilk and colleagues (1993), comprising ten different exercises, will be applied to both the experimental and control groups. In the experimental group, an external focus of attention strategy will be employed, directing participants' attention away from their body movements toward external targets (e.g., a target board used in conjunction with a laser pointer) during the execution of the exercises.
