Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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?
-Does performing the abdominal bracing maneuver increase the upper extremity performance in adolescent female volleyball athletes?

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.
