About this study

Official title: Does Abdominal Bracing Affect the Upper Extremity Performance in Female Adolescent Volleyball Athletes?

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?

Read the detailed description

This study aims to determine the acute effects of abdominal bracing maneuver on the stability and strength of the upper extremity. Trunk co-activation maneuvers, also known as volitional preemptive abdominal contraction or abdominal stabilization maneuvers, are developed to prevent and treat spinal instability by boosting core muscle activity. Since core muscles are essential for providing proximal stabilization and maximal force during various activities, take part in the energy transfer between the upper and lower extremities, and reduce the load on the joints; performing the maneuver may increase the athlete's performance.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Abdominal Bracing TrainingOther

    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.

Receives: Other: Abdominal Bracing Training

What is being measured

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

  1. 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.

    Measured: Day 1

  2. Seated Medicine Ball Throw

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

    Measured: Day 1
