AI Article Synopsis

  • This study establishes normative strength data for the thighs of soccer players, focusing on differences by position using extensive isometric and isokinetic measurements.
  • A total of 364 players were assessed, with significant differences found in isokinetic strength of the quadriceps between strikers and central midfielders, but no other position-related differences in strength were noted.
  • Overall, the findings suggest that strength profiles are similar across different playing positions, providing important insights for coaches and medical teams in training and rehabilitation programs.

Article Abstract

Background: This study aimed to further complete normative data sets for the strength profile of the thigh in soccer players by performing isometric and isokinetic measurements in a large sample per player position.

Methods: In total, 364 soccer players were divided into subgroups according to their pitch position. All players performed isometric and isokinetic strength measurements during active competition period using an isokinetic dynamometer (System 3, Biodex, ENRAF-NONIUS, New York, USA).

Results: Isokinetic strength of m. Quadriceps was significantly (p = 0.023) higher in strikers compared to central midfielders in both the dominant (+ 9%) and the non-dominant (+ 4%) leg. No further differences were found in isometric or isokinetic strength per playing positions.

Conclusions: We have shown that strength profiles do not differ between playing positions on the field. This is valuable information for elite soccer high performance coaches and medical staffs aiming to improve daily training efficiency and rehabilitation of their players.
