Summary

The purpose of this study is to examine the effects of a 12-week volleyball-specific warm-up program (VOLLEY12+) on neuromuscular performance in young male volleyball players. Neuromuscular performance is an important factor related to injury risk and athletic performance in youth sports. Twenty-four male volleyball players aged 15 to 17 years were allocated into an intervention group or a control group. The intervention group performed the VOLLEY12+ warm-up program before each training session for 12 weeks, while the control group continued their usual coach-led warm-up routines. Neuromuscular performance was assessed before and after the intervention using balance and movement control tests, including the Balance Error Scoring System (BESS), the Landing Error Scoring System (LESS), and the Y Balance Test. The results of this study will help determine whether a structured, sport-specific warm-up program can improve neuromuscular performance in adolescent volleyball players and support the use of injury prevention strategies in youth volleyball training.

Interventions

Type	Name	Description
OTHER	Regular Coach-Led Volleyball Warm-Up	Participants performed their usual coach-led warm-up routine prior to volleyball training. This routine consisted of low-intensity jogging, dynamic mobility, and stretching exercises, followed by basic volleyball-specific ball-handling drills. No structured injury-prevention or neuromuscular training components were included, and the content was not modified by the research team.
OTHER	VOLLEY12+ Volleyball-Specific Warm-Up Program	A progressive volleyball-specific neuromuscular warm-up program (VOLLEY12+) performed before regular training sessions over a 12-week period. The program was designed to enhance dynamic balance, neuromuscular control, and landing mechanics by targeting the ankle, knee, hip, and shoulder regions. Exercises were progressively overloaded using changes in volume, distance, and external resistance, and the total duration of each session was approximately 16-20 minutes.
