About this study
Official title: Comparison of Functional Movement, Dynamic Balance, and Lower Extremity Muscle Strength Between Professional and Amateur Soccer Players
This observational comparative study aims to evaluate differences in functional movement quality, dynamic balance, lower extremity muscle strength, and jumping performance between professional and amateur male soccer players. A total of 144 licensed soccer players (72 professional and 72 amateur) will undergo standardized assessments, including the Functional Movement Screen (FMS), Y-Balance Test (YBT), countermovement jump (CMJ), vertical jump (VJ), one-repetition maximum (1RM) strength tests, and eccentric hamstring strength assessment using the NordBord system. The findings are expected to improve understanding of how competitive level influences physical performance characteristics and may contribute to the development of evidence-based training, injury prevention, and athlete development strategies.

Countermovement Jump (CMJ) Height
Lower-extremity explosive power measured as countermovement jump height using the Witty Microgate system.
Measured: Baseline (Day 1)
Vertical Jump (VJ) Height
Vertical jump performance assessed using the Witty Microgate system.
Measured: Baseline (Day 1)
One-Repetition Maximum (1RM) Strength
Maximum lower-extremity strength assessed using one-repetition maximum squat and deadlift tests.
Measured: Baseline (Day 1)

Questions about this trial
What is this clinical trial studying?
An observational study of Athletic Performance and Functional Movement, run by Istanbul Gelisim 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 5 inclusion and 5 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 14 Jul 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?
Functional Movement Screen (FMS) Total Score (time frame: Baseline (Day 1)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 14 Jul 2026; AzTrials last refreshed its copy on 8 Nov 2026.
