Dynamic trunk stabilization: a conceptual back injury prevention program for volleyball athletes

Area of Science:

• Sports Medicine
• Biomechanics
• Exercise Physiology

Background:

• Volleyball demands significant dynamic trunk stability.
• Back injuries are prevalent in volleyball, especially among female athletes.
• Understanding trunk anatomy and muscle function is crucial for injury prevention.

Purpose of the Study:

• To review functional anatomy and muscle coactivation in volleyball.
• To assess trunk muscle performance and identify effective core exercises.
• To present a progressive training program for dynamic trunk stability and back injury reduction.

Main Methods:

• Review of functional anatomy and muscle coactivation strategies.
• Assessment of trunk muscle performance and exercise characteristics.
• Development of a conceptual 3-phase volleyball-specific training program.

Main Results:

• Phase 1: Focuses on low-velocity motor control, awareness, and endurance with neutral spine alignment.
• Phase 2: Integrates higher-velocity, multiplanar movements with strength-power challenges.
• Phase 3: Incorporates volleyball skill simulations with varying stability demands.

Conclusions:

• A progressive 3-phase training program can enhance dynamic trunk stability.
• This program has the potential to reduce back injury incidence in volleyball athletes.
• Further prospective research is required to validate the program's effectiveness.
