Functional Movement, Balance, and Strength in Professional and Amateur Soccer Players

NCT07702370 | Completed

• 1 other identifier: IGU-FMS-2025-01
• Study Type: observational
• Target: 144
• Locations: 1 country

Brief Summary

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.

Conditions

Athletic Performance; Functional Movement; Muscle Strength

Study Arms (2)

Professional Soccer Players

Male licensed professional soccer players competing in professional soccer leagues. Participants underwent assessments of functional movement, dynamic balance, lower extremity muscle strength, eccentric hamstring strength, and jumping performance. No intervention was administered.

Other: Physical Performance Assessment

Amateur Soccer Players

Male licensed amateur soccer players competing in amateur soccer leagues. Participants underwent the same assessment protocol as the professional group. No intervention was administered.

Other: Physical Performance Assessment

Interventions

Physical Performance Assessment OTHER

Standardized physical performance assessment 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. No therapeutic or experimental intervention was administered.

Amateur Soccer Players; Professional Soccer Players

Eligibility Criteria

• Age: 18 Years - 35 Years
• Sex: male
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)
• Sampling Method: Non-Probability Sample

Study Population

The study population consisted of healthy licensed male soccer players actively competing in professional and amateur soccer leagues. A total of 144 participants (72 professional and 72 amateur) were recruited during the competitive season. All participants regularly participated in team training (4-5 sessions per week) and official league matches. The study population was selected to compare functional movement quality, dynamic balance, lower extremity muscle strength, and jumping performance between different competitive levels in soccer.

You may qualify if:

• Male licensed soccer players.
• Professional or amateur soccer players actively competing during the study period.
• Regular participation in team training (4-5 sessions per week) and official competitions.
• Ability to complete all physical performance assessments.
• Provided written informed consent before participation.

You may not qualify if:

• Current musculoskeletal injury or pain affecting performance.
• History of lower-extremity injury preventing full participation in testing.
• Neurological, cardiovascular, or other medical conditions limiting physical performance.
• Inability or unwillingness to complete all assessment procedures.
• Withdrawal of informed consent.
