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

9. juli 2026 oppdatert av: Görkem Açar, Istanbul Gelisim University

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.

Studiepopulasjon

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.

  • Ability to complete all physical performance assessments.
  • Provided written informed consent before participation.

Exclusion Criteria:

  • Current musculoskeletal injury or pain affecting performance.

Kohorter og intervensjoner

Gruppe / Kohort
Intervensjon / Behandling
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.
Annen: Physical Performance Assessment
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
Male licensed amateur soccer players competing in amateur soccer leagues. Participants underwent the same assessment protocol as the professional group. No intervention was administered.
Annen: Physical Performance Assessment
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.
