Relația dintre forța trenului inferior, a vitezei de accelerare și capacitatea de schimbare a direcției la jucătoarele de fotbal senioare [Articol]

Abstract

The present study investigates the relationship between lower body strength, acceleration speed, and change of direction ability in senior female football players, within the context of modern game demands. The research was conducted on a sample of 15 competitive-level athletes, using specific tests to assess agility (5-0-5, Illinois), maximal strength (leg press 3RM), and strength endurance (bodyweight squats in 60 seconds). Descriptive analysis revealed a relatively homogeneous profile of speed and agility performance, characterized by low coefficients of variation, indicating a stable functional level among players. In contrast, strength-related parameters showed greater variability, particularly in strength endurance. Pearson correlation analysis identified a strong relationship between left and right performance in the 5-0-5 test, suggesting well-developed bilateral neuromuscular control. Additionally, a significant negative correlation was found between agility performance and strength endurance, indicating that players with higher capacity for repeated effort tend to achieve better results in change of direction tasks. Conversely, maximal strength showed no significant associations with speed parameters. These findings highlight the importance of an integrated and individualized training approach, emphasizing strength endurance and neuromuscular control development to optimize performance in female football.
