Effects of lower extremity posture on hip strength and their influence on lower extremity motion during a single leg squat 2007 8236 "This research investigated the effects of static lower extremity posture on hip strength, and then examined their collective influence on knee and hip joint kinematics during a single leg squat in males and females. Thirty one healthy males and 31 h...
The effect of lean body mass and strength on lower extremity energy absorption strategies during landing 2011 6238 Lower amounts of lean body mass and strength in females compared to males have been proposed to result in greater relative task difficulty for females when asked to perform a standardized task and may explain sex differences in energy absorption stra...
Associations between physical characteristics and landing biomechanics in adolescent females 2013 3586 Females tear their anterior cruciate ligament (ACL) at a rate of four to six times that of similarly trained males. This greater risk of ACL injury in females begins to emerge around age 12, then peaks and remains elevated from age 15 into adulthood....
A comparison of knee muscle activation and knee joint stiffness between female dancers and basketball players during drop jumps 2007 4962 "This dissertation compared knee muscle activation of the lateral gastrocnemius, medial and lateral hamstrings, and lateral quadriceps (LG, MH, LH, and LQ) and knee joint stiffness(KJS) between female dancers(D) and basketball players(B) during the i...
The ability of the FMS to predict knee injury in female collegiate athletes 2014 7208 Non-contact knee injuries are one of the most common injuries among athletes that participate in sports that require cutting, quick deceleration and jumping actions. Researchers and clinicians have attempted to develop screening tools to identify tho...
Effect of ankle dorsiflexion range of motion on knee biomechanics: implications for patellofemoral pain syndrome 2014 3128 Patellofemoral pain syndrome (PFPS), or pain in the area of the kneecap, has been diagnosed in as many as one in four patients seen at a sports medicine clinic, yet its etiology and risk factors are surprisingly not well understood (Devereaux & Lachm...
The Relationship Between Anterior Pelvic Tilt, Hamstring Extensibility and Hamstring Strength 2008 10007 The purpose of this study was to investigate the relationship between hamstring extensibility and pelvic tilt, and their collective impact on hamstring strength. The first objective was to examine the relationship between anterior pelvic tilt and ham...
Development of an anatomical landmark protocol for constructing segment axes for lower extremity kinematic analysis 2005 2713 "The objective of this study was to determine whether a landmark protocol could reliably gather more anatomically accurate data than the default software setting for an electromagnetic tracking system. Nineteen healthy participants (10 males, 9 fema...
Anatomical and neuromuscular contributions to anterior knee shear force during single-leg landings in females 2005 3682 "This research investigated the collective interactions between hamstrings extensibility, anterior knee laxity, and hamstrings and quadriceps muscle activation as predictors of anterior knee shear forces during single-leg landings in females. Forty-f...
Comparison of neuromuscular control strategies between collegiate female dancers and athletes 2014 1854 High risk neuromuscular control strategies during landing and cutting maneuvers are thought to be a major contributing factor to the 6 times greater risk of ACL injury in female athletes compared to male athletes. However, female dancers who have sim...
Differential biomechanical effects of an ACL injury prevention program in women’s basketball and soccer players 2016 1319 Anterior cruciate ligament (ACL) injury prevention programs are considerably less successful in women’s basketball than women’s soccer. Despite different sport-specific demands (e.g. more jumping and frontal plane movements in basketball), ACL injury...
The influence of femoral structure, hip capsular constraints, and gluteal muscle strength and activation on temporal patterns of functional valgus collapse 2018 593 Functional valgus collapse (a combination of knee abduction and internal rotation and hip adduction and internal rotation) is a modifiable lower extremity movement pattern commonly associated with anterior cruciate ligament (ACL) injuries in females....
Hormone status and measures of joint laxity 2007 3208 "This study examined the relationships between oral contraceptive pill (OCP) use and measures of joint laxity. Methods: A menstrual history questionnaire identified 33 female athletes using OCPs. Separate stepwise linear regressions examined the exte...
The influence of hamstring musculo-articular stiffness on biomechanical factors indicative of anterior cruciate ligament loading 2017 177 Noncontact anterior cruciate ligament (ACL) injuries commonly occur upon initial foot contact (IC) with the ground during single-leg cutting or jump-landing maneuvers. Because these injuries occur in the absence of physical contact with another playe...
