PCA. 16 Our purpose was therefore to examine changes in participant-specific single-leg landing strategies and intra-individual movement variability following alterations in mechanical task demands via external load and landing height. We used the Load Accommodation Strategies Model 17 , 21 – 23 to

scores. In this sporting context, it has been suggested ( Emery, 2003 ; McKeon & Hertel, 2008 ) that the single-leg balance most accurately replicates sporting movements and may better encompass an athlete’s potential to maintain balance as opposed to bilateral (two-legged) balance. Further, as athletes
The Role of Anthropometric Parameters on Single-Leg Balance Performance in Young Sub-Elite Soccer Players
Dirk Krombholz, Luca Daniel, Peter Leinen, Thomas Muehlbauer, and Stefan Panzer
in their analyses. For example, to determine performance asymmetry in leg stability, single-leg balance performance is evaluated. In some studies, balance performance was compared between the dominant and non-dominant leg of children, young adults, and adolescents (e.g., Leinen, Muehlbauer, & Panzer
Single-Leg Balance Performance in Sub-Elite Young Soccer Players and Swimmers as a Function of Age and Sports Experience
Peter Leinen, Thomas Muehlbauer, and Stefan Panzer
performed a single-leg stance task worse than older athletes aged between 16 and 18 years, and that young athletes showed a greater right to left asymmetry in balance control than older athletes. However, while the factor age has received some attention, little attention has been directed to the question if
Differentiating Successful and Unsuccessful Single-Leg Drop Landing Performance Using Uncontrolled Manifold Analysis

to data from single-leg landing tasks—often used in the biomechanics literature to assess injury risk ( Ali et al., 2013 ; Ford et al., 2006 ; Kipp, McLean, & Palmieri-Smith, 2011 )—to examine the reciprocal compensation among musculoskeletal DOF (i.e., angular motion at the trunk, hip, knee, and
Prelanding Knee Kinematics and Landing Kinetics During Single-Leg and Double-Leg Landings in Male and Female Recreational Athletes
Ling Li, Yu Song, Maddy Jenkins, and Boyi Dai
. 4 , 10 , 11 Studies have shown that single-leg landings are more likely to result in increased ACL loading than double-leg landings because of greater impact forces and decreased knee flexion angles during the landing phase. 10 – 13 In addition, some studies found that females demonstrated lower
Effect of Single-Leg Squat Speed and Depth on Dynamic Postural Control Under Single-Task and Dual-Task Paradigms
Maria K. Talarico, Robert C. Lynall, Timothy C. Mauntel, Erin B. Wasserman, Darin A. Padua, and Jason P. Mihalik
The single-leg squat is a common clinical assessment evaluating lower extremity musculoskeletal and dynamic postural control deficiencies. 1 – 6 Standard practice for clinically assessing single-leg squat functional and balance performance involves visually observing movement patterns throughout
Postural Control Adaptations in Yoga Single-Leg Support Postures: Comparison Between Practitioners and Nonpractitioners

the role of regular physical and mental practice on motor control and motor execution strategies. Regular Yoga practitioners undergo body and mind exercises, which facilitate and actively stabilize mechanically unstable positions, such as single-leg stance, while the upper body assumes unusual
Muscular Coordination of Single-Leg Hop Landing in Uninjured and Anterior Cruciate Ligament-Reconstructed Individuals

. 2 Increasing the rate of postsurgery participation in sport represents a challenge to rehabilitation research and may be garnered through improvements in clinical assessment. The single-leg hop for distance is a well-studied and routinely employed task in the functional evaluation of ACLR
Comparison of 5 Normalization Methods for Knee Joint Moments in the Single-Leg Squat

assessed using NJM about the mediolateral (NJM-ML) and anteroposterior (NJM-AP) axes of the knee joint during a single-leg squat movement, using data extracted from a published study that were collected for a different purpose. 13 It was hypothesized that dividing NJM by mass × height and mass × leg
