“…A recent study performed by Mache et al [63] compared landing kinetics and kinematics between anticipated and unanticipated conditions. In this study, anticipated condition at initial contact produced lower hip and knee flexion, lower knee abduction and higher ankle plantar flexion in the drop jump, and lower hip abduction and higher ankle plantar flexion in drop landing compared with preplanned condition.…”

Prevention of anterior cruciate ligament (ACL) injury is likely the most effective strategy to reduce undesired health consequences including reconstruction surgery, long-term rehabilitation, and pre-mature osteoarthritis occurrence. A thorough understanding of mechanisms and risk factors of ACL injury is crucial to develop effective prevention programs, especially for biomechanical and neuromuscular modifiable risk factors. Historically, the available evidence regarding ACL risk factors has mainly involved female athletes or has compared male and female athletes without an intra-group comparison for male athletes. Therefore, the principal purpose of this article was to review existing evidence regarding the investigation of biomechanical and neuromuscular characteristics that may imply aberrant knee kinematics and kinetics that would place the male athlete at risk of ACL injury. Biomechanical evidence related to knee kinematics and kinetics was reviewed by different planes (sagittal and frontal/coronal), tasks (single-leg landing and cutting), situation (anticipated and unanticipated), foot positioning, playing surface, and fatigued status. Neuromuscular evidence potentially related to ACL injury was reviewed. Recommendations for prevention programs for ACL injuries in male athletes were developed based on the synthesis of the biomechanical and neuromuscular characteristics. The recommendations suggest performing exercises with multi-plane biomechanical components including single-leg maneuvers in dynamic movements, reaction to and decision making in unexpected situations, appropriate foot positioning, and consideration of playing surface condition, as well as enhancing neuromuscular aspects such as fatigue, proprioception, muscle activation, and inter-joint coordination.

“…Given the aforementioned discrepancies among studies that have addressed the effects of anticipation on neuromechanical changes of the lower extremity, 9,14,17,18,23,24 it may also be prudent to consider general limitations to unanticipated models that are commonly used in the literature. Arguably, participants may simply assume less dangerous landing mechanics when completing tasks under unanticipated conditions compared with anticipated conditions.…”

“…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.…”

Context Continued research into the mechanism of noncontact anterior cruciate ligament injury helps to improve clinical interventions and injury-prevention strategies. A better understanding of the effects of anticipation on landing neuromechanics may benefit training interventions. Objective To determine the effects of anticipation on lower extremity neuromechanics during a single-legged land-and-cut task. Design Controlled laboratory study. Setting University biomechanics laboratory. Participants Eighteen female National Collegiate Athletic Association Division I collegiate soccer players (age = 19.7 ± 0.8 years, height = 167.3 ± 6.0 cm, mass = 66.1 ± 2.1 kg). Intervention(s) Participants performed a single-legged land-and-cut task under anticipated and unanticipated conditions. Main Outcome Measure(s) Three-dimensional initial contact angles, peak joint angles, and peak internal joint moments and peak vertical ground reaction forces and sagittal-plane energy absorption of the 3 lower extremity joints; muscle activation of selected hip- and knee-joint muscles. Results Unanticipated cuts resulted in less knee flexion at initial contact and greater ankle toe-in displacement. Unanticipated cuts were also characterized by greater internal hip-abductor and external-rotator moments and smaller internal knee-extensor and external-rotator moments. Muscle-activation profiles during unanticipated cuts were associated with greater activation of the gluteus maximus during the precontact and landing phases. Conclusions Performing a cutting task under unanticipated conditions changed lower extremity neuromechanics compared with anticipated conditions. Most of the observed changes in lower extremity neuromechanics indicated the adoption of a hip-focused strategy during the unanticipated condition.

“…These tasks do not reflect the random nature of sports where participants are often required to respond to a number of different stimuli simultaneously and have to make adjustments during landing/cutting activity in response to these stimuli. This has led to recent research examining landing biomechanics during anticipated and unanticipated tasks to investigate the effects of decision-making on landing biomechanics (Brown, Palmieri-Smith, & McLean, 2009;Houck, Duncan, & De Haven, 2006;Mache, Hoffman, Hannigan, Golden, & Pavol, 2013;McLean, Borotikar, & Lucey, 2010). For example, Houck et al, (2006) compared trunk orientation in the frontal plane (trunk position relative to the global vertical position), trunk lateral flexion (trunk position relative to the pelvis segment), lateral foot placement, frontal plane hip angle along with hip and knee moments in the frontal plane during anticipated and unanticipated straight line walking and side cutting (approximately 50°change of direction) tasks.…”

“…Since ACL injury is likely to occur during more dynamic activities it limits the validity of the findings of this study and more research needs to be done in activities more representative of tasks in which ACL injury is common. In addition, as with Mache et al, (2013), all unanticipated tasks were completed after the anticipated tasks. The non-randomised order of the pre-planned and decision-making conditions suggest that learning and fatigue effects may have occurred, limiting the strength of any conclusions made.…”
