About

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.

24 participants in 2 patient groups

VOLLEY12+ Group

Experimental group

Description:

Participants performed a progressive volleyball-specific neuromuscular warm-up program (VOLLEY 12+) before each training session for 12 weeks. The program lasted 16-20 minutes and included dynamic mobility, balance, landing mechanics, trunk and hip control, and shoulder activation exercises.

Treatment:

Other: VOLLEY12+ Volleyball-Specific Warm-Up Program

Control Group

Active Comparator group

Description:

Participants performed their usual coach-led warm-up routines before each training session for 12 weeks. The routine included low-intensity jogging, dynamic mobility and stretching exercises, and volleyball-specific ball-handling activities, without any structured neuromuscular or injury-prevention content.

Treatment:

Other: Regular Coach-Led Volleyball Warm-Up
