Changes in Isokinetic Muscle Strength in Adolescent Soccer Players after 10 Weeks of Pre-Season Training

Popis výsledku v původním jazyce

The aim of the study was to evaluate changes in isokinetic strength of the knee flexors and extensors and their strength ratios in elite adolescent soccer players. Before and after 10 weeks of standard pre-season soccer training with progressive eccentric hamstring exercises, the players (n=18; age 17.1±0.4 years) participated in isokinetic testing to assess concentric and eccentric peak torque (PT) at 60°·s-1. After 10 weeks of training, the eccentric PT of the non-dominant quadriceps (Q) increased (p=0.018; ω=0.24). Additionally, the average eccentric work increased in the dominant hamstrings (H); (p=0.007; ω=0.23), dominant Q (p=0.02; ω=0.31), nondominant H (p=0.003; ω=0.25) and non-dominant Q (p=0.01; ω=0.37). Lastly, the isokinetic functional ratio (eccentric H-to-concentric Q) increased in the non-dominant limb (p=0.04; ω=0.31). The results of the study indicate that pre-season training induced suboptimal changes in the isokinetic strength of the knee flexors and extensors in elite adolescent soccer players.
