PURPOSE Evasive sidestepping during sports commonly results in noncontact anterior cruciate ligament injuries. Sidestepping in response to different simple visual stimuli has been studied previously but never investigated using quasi-game-realistic visual conditions. We compared the biomechanics of high-level and low-level soccer players when sidestepping in response to projected, three-dimensional defender(s) and the traditionally used planned and unplanned arrow stimuli. METHODS A three…

Different visual stimuli affect muscle activation at the knee during sidestepping

High-level players were better at interpreting complex game-realistic information (2DS) to activate their knee extensors earlier in preparation for single-leg landing during weight-acceptance as well as when the time demands to respond were low.

Different visual stimuli affect body reorientation strategies during sidestepping

Higher level perception of game‐realistic visual information could have contributed to this safer neuromuscular strategy that, when understood better, could potentially be trained in lower level players to reduce ACL injury risk associated with dangerous sidestepping postures.

Type of unanticipated stimulus affects lower extremity kinematics and kinetics during sidestepping

The effects of two types of unanticipated stimuli (visual stimulus; defensive opponent) on lower extremity kinematics and kinetics in males and females during 45° sidestepping trials were determined.

Field hockey sport-specific postures during unanticipated sidestepping: Implications for anterior cruciate ligament injury prevention

The findings indicate that field hockey players sidestep with significantly different techniques when holding a hockey stick, which should be considered in injury prevention training protocols.

Knee Mechanics During Planned and Unplanned Sidestepping: A Systematic Review and Meta-Analysis

A rationale for the incorporation of unplanned sport tasks in the development of anterior cruciate ligament injury screening and in prophylactic training programmes is proposed.

Whole-body control of anticipated and unanticipated sidestep manoeuvres in female and male team sport athletes

The current research draws attention to the foreseen benefits of training athletes, with particular emphasis on females, to direct CoM towards the desired direction of travel in the preparatory and stance phases within temporally constrained situations for improved performance.

Decision Making Influences Tibial Impact Accelerations During Lateral Cutting.

Both males and females demonstrated higher impact accelerations and a trend toward greater intertrial variability for the unplanned cutting trials (vs preplanned cuts).

Investigation of the Effects of High-Intensity, Intermittent Exercise and Unanticipation on Trunk and Lower Limb Biomechanics During a Side-Cutting Maneuver Using Statistical Parametric Mapping

Center of Pressure and Perceived Stability in Basketball Shoes With Soft and Hard Midsoles.

Investigation of the effects of varying midsole hardness on center of pressure (COP) and perceived stability during basketball-specific tasks, as well as the correlation between COP and perception measurements found no significant correlationbetween COP and perceived Stability during layup or 45° cutting.



Effect of gender and defensive opponent on the biomechanics of sidestep cutting.

Gender differences in the joint kinematics suggest that increased kneevalgus may contribute to ACL injury risk in women, and that the hip and ankle may play an important role in controlling knee valgus during sidestepping.

Stereoscopic filming for investigating evasive side-stepping and anterior cruciate ligament injury risk

It is proposed that stereoscopically filmed footage featuring sport specific opposing defender/s simulating a tackle on the viewer, when used as visual stimuli, could improve the ecological validity of laboratory based investigations of evasive Ssg.

Anticipatory effects on knee joint loading during running and cutting maneuvers.

Cutting maneuvers performed without adequate planning may increase the risk of noncontact knee ligament injury due to the increased external varus/valgus and internal/external rotation moments applied to the knee.

Changing Sidestep Cutting Technique Reduces Knee Valgus Loading

Implementation of whole body technique modification may produce effective ACL injury prevention programs in sports involving sidestep cutting, and resulted in reduced knee loading.

The effect of technique change on knee loads during sidestep cutting.

Sidestep cutting technique had a significant effect on loads experienced at the knee, such as foot wide, torso leaning in the opposite direction to the cut and torso rotating in the same direction as the cut, which place an athlete at higher risk of injury.

Sex and limb differences in hip and knee kinematics and kinetics during anticipated and unanticipated jump landings: implications for anterior cruciate ligament injury

UN landings induce modifications in landing biomechanics that may increase anterior cruciate ligament injury risk in both men and women, but these modifications do not appear overly sensitive to the timing of the UN stimulus, at least within a temporal range affording a successful movement response.

Effect of attending to a ball during a side-cut maneuver on lower extremity biomechanics in male and female athletes

Results did not indicate that the effect of attention varies with gender, however, during side-cut conditions while attending to a ball, internal knee adductor moment was 20% greater and peak knee flexion angle was 4° larger than average for males and females.

Mechanisms of Anterior Cruciate Ligament Injury in Basketball

Female players landed with significantly more knee and hip flexion and had a 5.3 times higher relative risk of sustaining a valgus collapse than did male players, and movement patterns were frequently perturbed by opponents.
