Brief Summary

The goal of this cross-sectional study is to investigate the effects of abdominal bracing, a trunk co-activation maneuver that activates core muscles, on upper extremity performance tests in adolescent female volleyball athletes. The main question it aims to answer is:

• Does performing the abdominal bracing maneuver increase the upper extremity performance in adolescent female volleyball athletes?

Conditions

Upper Extremity Injury

Keywords

Core stabilization; Adolescent athletes; Abdominal bracing maneuver; Functional Performance

Outcome Measures

Primary Outcomes (2)

• Closed Kinetic Chain Upper Extremity Stability Test

  Participants were asked to perform the test with and without the abdominal bracing maneuver. Stability of the closed kinetic chain was assessed.

  Day 1

• Seated Medicine Ball Throw

  Participants were asked to perform the test with and without the abdominal bracing maneuver. Open kinetic chain was assessed.

  Day 1

Study Arms (1)

Adolescent volleyball athletes

Athletes between the ages of 12-18 were recruited as this study has only one group.

Other: Abdominal Bracing Training

Interventions

Abdominal Bracing Training OTHER

The group underwent an abdominal bracing maneuver training. Following the training, they performed the Closed Kinetic Chain Upper Extremity Stability Test and the Seated Medicine Ball Throw Test in 2 conditions: with abdominal bracing and without abdominal bracing.

Adolescent volleyball athletes
