virtual reality training was accomplished by incorporating the following six games into circuit training: jogging for gait, swordplay for agility and balance, ski jump for balance, hula-hoop for balance and lower extremity strength, tennis for balance and agility, and step dance for gait and lower

downstream effects, such as muscle atrophy or mental health issues associated with time away from sport. 2 , 3 Concussions, and concussion history, pose an additional concern for athletes and coaches. The risk of sustaining a lower extremity injury increases following a concussion. 4 – 6 Further, female
Lower-Extremity Motor Synergies in Individuals With and Without Chronic Ankle Instability
Adam E. Jagodinsky, Rebecca Angles, Christopher Wilburn, and Wendi H. Weimar
potential adaptations manifesting in motor strategies, previous studies have primarily focused on investigating individual lower-extremity joint movement and motor patterns during gait or drop landing between individuals with and without chronic ankle instability. 17 – 21 Yet, fewer studies have focused on
Cancer-Specific Mortality Relative to Engagement in Muscle-Strengthening Activities and Lower Extremity Strength
Scott J. Dankel, Jeremy P. Loenneke, and Paul D. Loprinzi
Previous research has demonstrated that having adequate lower extremity and upper body muscle strength (generally defined as averting the lower tertile or quartile) reduces the risk of all-cause mortality 1 – 3 ; however, less overt is the importance of skeletal muscle strength on cancer
Validation of Smartphone Accelerometry for the Evaluation of Sit-To-Stand Performance and Lower-Extremity Function in Older Adults
Yuwei Song, Momotaz Begum, Sajay Arthanat, and Dain P. LaRoche
Frequent and long-term monitoring of sit-to-stand (STS) time in older adults using body-worn mobile devices has the potential to increase the utility of this lower-extremity performance marker. Diminished lower-extremity function is associated with greater activity of daily living disability
Abdominal Circumference Versus Body Mass Index as Predictors of Lower Extremity Overuse Injury Risk
Nathaniel S. Nye, Drew S. Kafer, Cara Olsen, David H. Carnahan, and Paul F. Crawford
Lower extremity overuse injuries (LEOIs) are common in outpatient clinics 1 , 2 and are observed in both younger and older patients and in both the elite athlete 3 as well as the sedentary 4 individual. These injuries are particularly troublesome for the military, as they impair the ability to
Reliability of Using a Handheld Tablet to Analyze Lower Extremity Landing Mechanics During Drop Vertical Jumps

lower extremity (LE) movement patterns during athletic skills have been shown to increase the risk of knee injury. 1 – 4 Absorption patterns associated with LE injuries include decreased hip flexion, 5 knee flexion, 5 and abduction 6 position at initial contact with the ground, decreased hip flexion
High-Risk Lower-Extremity Biomechanics Evaluated in Simulated Soccer-Specific Virtual Environments
Christopher A. DiCesare, Adam W. Kiefer, Scott Bonnette, and Gregory D. Myer
. Participants Thirty-eight healthy, female adolescent soccer athletes (mean [SD]; age = 16.0 [1.3] y, height = 1.65 [5.5] m, and weight = 59.5 [9.9] kg) participated in this study. All athletes had no recent history of lower-extremity injury or other neuromuscular contraindications that would prevent them from
Sequential Pulse Compression’s Effect on Blood Flow in the Lower-Extremity

secondary ACL injuries that inequitably impact physically active females. Although a variety of nonmodifiable (e.g., sex, age, prior ACLR) and modifiable (e.g., lower-extremity biomechanics, sport participation) ACL injury risk factors have been identified over the past three decades, 4 – 7 recent
