Changes in injury risk mechanisms after soccer specific fatigue in male youth soccer players

Popis výsledku v původním jazyce

The aim of this study was to examine the acute effects of soccer specific fatigue on muscular and neuromuscular function. Elite players (n = 20; age 15.7 ± 0.5 y; body height 177.75 ± 6.61 cm; body mass 67.28 ± 8.29 kg) were measured before and after soccer specific exercise (SAFT90). The reactive strength index (RSI), leg stiffness (LS) and a functional hamstring to quadriceps strength ratio from isokinetic strength of the dominant and non-dominant leg (measured at angular velocities of 1.05 rad ∙ s−1 and 3.14 rad ∙ s−1) were assessed. Metabolic response to the SAFT90 was determined by blood lactate and perceived exertion was assessed by the Borg scale. A significant decrease in absolute LS (t = 4.411; p &lt; 0.001; ω2 = 0.48) and relative LS (t = 4.326; p &lt; 0.001; ω2 = 0.49) was observed and the RSI increased significantly (t = 3.806; p = 0.001; ω2 = 0.40). A reduction in LS found after the SAFT90 indicates possible reduction in dynamic knee stabilization. However, if we consider the changes in other observed variables, the present study did not clearly confirm that fatigue induced by a soccer specific protocol increased the risk of ACL and hamstring injury.
