Effect of Anticipation on Lower Extremity Biomechanics During Side- and Cross-Cutting Maneuvers in Young Soccer Players

Abstract

Increases in the valgus angle and moment of the knee joint and higher lateral gastrocnemius activity during the late period showed an association with ACL injury risk factors during side-cutting, and higher lateral gastrocnemius activity during the early period showed an association with injury risk factors during cross-cutting.

Anticipatory Effects on Lower Extremity Neuromechanics During a Cutting Task

“…2,5 To develop clinical interventions that aim to prevent injuries, research efforts have been directed at determining how biomechanical and neuromuscular risk factors manifest within the ACL injury mechanism. [6][7][8][9][10][11][12][13][14][15][16] Most authors 9,14,17,18 who investigated these risk factors and their role in the ACL injury mechanism focused on kinetic and kinematic variables measured during landing and cutting tasks. These results suggest that deleterious knee kinetics are characterized by greater external-flexion, abduction, and internal-rotation moments.…”

“…Researchers, therefore, try to mimic the uncertainty of these conditions by having participants perform tasks without knowing which direction to move in before they actually initiate the movement. 7,9,12,14,15,17,18,23,24 It is interesting, however, that direct comparisons between lower extremity mechanics performed under anticipated and unanticipated conditions have not been conducted as often as comparisons between groups that performed only unanticipated conditions. Yet, analyzing biomechanical and neuromuscular variables under either condition alone may not provide sufficient information about the neuromechanical strategies that athletes adopt when faced with situations that more closely resemble the dynamic athletic environment.…”

“…The few researchers 12,14,15 who directly compared anticipated and unanticipated conditions generally indicated that lower extremity mechanics were exacerbated when movement tasks were performed under unanticipated conditions. These results, however, primarily described differences in knee-joint biomechanics (ie, kinematics and kinetics) between movement tasks performed under anticipated and unanticipated conditions.…”

The Effects of a Cognitive Dual Task on Jump-landing Movement Quality

“…This can result in athletes with lower visual attention abilities having delayed processing when confronted with unexpected sensory events or when employing cognitive or visual resources to interact with the environment, potentially resulting in impaired neuromuscular control and eleveated injury risk [5]. These findings have been supported in other studies illustrating that there is impaired neuromuscular control, decreased anticipation ability, and preparedness when an individual is under cognitive load [35,[46][47][48][49]. In our study, the tuck jump score increased significantly (indicating reduced neuromuscular control and higher injury risk movements) from baseline to both easy and difficult cognitive dual-task conditions.…”

Fußballsport als Risikofaktor für nicht unfallbedingte Gonarthrose – Ergebnisse eines systematischen Review mit Metaanalyse

“…Dies hängt ab von der Spielerposition, dem Geschlecht, dem Alter des Spielers, seinem Trainingszustand, aber auch von anatomischen Gegebenheiten (Varus-oder Valgus Typ) [21,50]. Vergleicht man diese Spitzenbelastungen jedoch mit anderen körperlichen Aktivitäten (forcierter Gang, schnelles Treppablaufen, andere Sportarten, körperlich schwere Berufe), so unterscheiden sich diese nicht [42,50,54,55,68]. In einem bandstabilen Kniegelenk werden auch während der Spitzenbelastung beim Fußballsport keine Druckund Scherspannungen erreicht, die zu einer mechanischen Schädigung des hyalinen Gelenkknorpels führen [76,78].…”
