Muscular and neuromuscular control following soccer-specific exercise in male youth: Changes in injury risk mechanisms

Popis výsledku v původním jazyce

The aim of this study was to explore the effects of soccer specific fatigue on neuromuscular control, reactive strength, leg stiffness and H/QFUNC in 18 elite male youth soccer players (age 14.4 ± 0.5 y). Muscle activation using EMG, isokinetic determined H/QFUNC, reactive strength and leg stiffness were measured in youth players pre and post simulated soccer match play (SAFT90). There was no fatigue related change in the H/QFUNC however, reactive strength and leg stiffness were both compromised (P &lt; 0.001) after soccer specific fatigue. Muscle activation was also locally compromised (P &lt; 0.001) in the medial hamstring and quadriceps. The corresponding effect sizes ranged from small to very high (0.33 – 0.97). Compromised stiffness when fatigue is present suggests an increased yielding action, greater ground contact times, greater center of mass displacement, and less efficient movement when the limb comes into contact with the ground. This combined with a localised reduction in muscle activation may reflect poor kinetic chain control at the hip and an increase in knee injury risk.
