About this study
Official title: Acute Effects of Basketball Training on Neuromuscular Performance and Dynamic Balance in Professional Adolescent Basketball Players: A Sex-Based Analysis
The primary aim of this study is to investigate the effects of acute fatigue on neuromuscular control and performance parameters in professional adolescent basketball players and to determine the relationship between fatigue level and neuromuscular control variables. As a secondary aim, the study seeks to examine whether these effects differ according to sex.
The research hypotheses are as follows. The null hypothesis (H1-0) states that acute fatigue has no significant effect on neuromuscular control parameters in adolescent basketball players, including balance performance, landing mechanics, ground contact time, and asymmetry ratios. The alternative hypothesis (H1-1) proposes that acute fatigue has a significant effect on these neuromuscular control parameters.
The second null hypothesis (H2-0) states that the effects of acute fatigue on neuromuscular control parameters do not differ according to sex. The alternative hypothesis (H2-1) suggests that the effects of acute fatigue on neuromuscular control parameters differ according to sex.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
basketball practiceOther
The athletes' training session will consist of a 30-minute general and sport-specific warm-up period followed by a 90-minute basketball-specific ball training session. These training sessions will be conducted in accordance with the club's standard training program and will include technical and tactical drills, game-based exercises, movements involving changes of direction, jump-landing activities, and short-duration sprint efforts.

What is being measured
The primary outcome is the main question the study is designed to answer.
Dynamic Balance
The Y-Balance Test (YBT) will be used to assess lower extremity dynamic balance, neuromuscular control, and functional stability. Participants balance on one leg while reaching as far as possible in the anterior, posteromedial, and posterolateral directions. A modified version of the YBT will be used due to the cost of the original platform, which has been shown to be reliable. Reach distances will be recorded in centimeters, normalized to lower extremity length, and a composite score (%) calculated:
Composite Score (%) = [(Anterior + Posteromedial + Posterolateral) / (3 × lower extremity length)] × 100
Higher scores indicate better dynamic balance and neuromuscular control.
Participant safety will be ensured with proper instructions, rest between trials, and termination of testing if pain or discomfort occurs. The YBT is non-invasive and safe.
Measured: At baseline and immediately after the training
Vertical jump
The Countermovement Jump (CMJ) test will be used to assess lower extremity neuromuscular fatigue. The CMJ is a widely used, valid, and reliable performance test in sports science, designed to evaluate explosive force production of the lower limb muscles, the elastic properties of the muscle-tendon unit, and neuromuscular function . Participants perform a maximal vertical jump from a standing position following a rapid eccentric knee and hip flexion. This test is particularly relevant in basketball due to its high ecological validity for jump and landing movements. During the CMJ, jump height and the flight time to contact time ratio (FT:CT) will be calculated. The FT:CT ratio is an indirect indicator of neuromuscular efficiency and fatigue, with literature showing a decrease as fatigue increases. Each participant will perform three trials, with 1-minute rest between trials, and the best performance will be used for analysis. The test will be terminated if any pain, discomfort, or risk
Measured: Baseline and immediately after the training

Questions about this trial
What is this clinical trial studying?
A study testing basketball practice in people with Fatigue Recovery and Basketball, run by Biruni University at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 Apr 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?
Dynamic Balance (time frame: At baseline and immediately after the training). The study lists 2 primary outcomes in all. 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 NCT07467525, which also lists 13 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 29 Apr 2026.
