Trial 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. Read more about this study

About this study

Official title: THE EFFECT OF VOLLEYBALL-SPECIFIC INJURY PREVENTION PROGRAM ON DYNAMIC BALANCE AND POSTURAL STABILITY IN YOUNG MALE VOLLEYBALL PLAYERS: A RANDOMIZED CONTROLLED TRIAL

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.

Conditions: Healthy, Healthy Adult Male, Volleyball Players, Injury Prevention in Sports, Neuromuscular Performance
Being tested: Regular Coach-Led Volleyball Warm-Up, VOLLEY12+ Volleyball-Specific Warm-Up Program

What participants receive

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

Regular Coach-Led Volleyball Warm-UpOther
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.
VOLLEY12+ Volleyball-Specific Warm-Up ProgramOther
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.

Study group	Role	What they receive
VOLLEY12+ Group	Experimental	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. Receives: Other: VOLLEY12+ Volleyball-Specific Warm-Up Program
Control Group	Active comparator	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. Receives: Other: Regular Coach-Led Volleyball Warm-Up

What is being measured

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

Static Balance Performance Assessed by the Balance Error Scoring System (BESS)
Static balance performance was assessed using the Balance Error Scoring System (BESS). Participants performed double-leg, single-leg, and tandem stances on firm and foam surfaces. Each stance was held for 20 seconds, and balance errors were recorded by a blinded assessor. Total error scores were calculated at baseline (pre-intervention) and after the 12-week intervention period.
Measured: Baseline and after 12 weeks

The record says: finished, as of the sponsor's last update on 20 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Static Balance Performance Assessed by the Balance Error Scoring System (BESS) (time frame: Baseline and after 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07351396, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jan 2026.
