Effect of Tuck Index on Impulse Produced during a Squat Jump in Swimmers 2008 5729 Knowing what amount of tuck, as measured by tuck index, produces the highest impulse values during the push-off, along with push off phase duration and distance traveled by the center of mass during the push off phase of a squat jump, will help to op...
Comparison of Problem Based Learning and Traditional Lecture Instruction on Critical Thinking, Knowledge, and Application of Strength and Conditioning 2008 12803 The purpose of this research was to compare the effects of problem based learning (PBL) and traditional lecture instruction (TI) courses on critical thinking, knowledge and application of strength and conditioning throughout a semester long collegiat...
Effects of augmented local abdominal activation patterns on lower extremity biomechanics during landing in males and females 2005 3063 "This research assessed changes in lower extremity biomechanics as a result of augmented local abdominal contractions during double leg landings. The study design followed a two-day (control and intervention days) within subject model in which two c...
Kinematic and kinetic effects of knee and ankle sagittal plane joint restrictions during squatting 2005 6833 "The purpose of this study was to evaluate compensatory biomechanical patterns in the lower extremity created by restricted knee flexion and ankle dorsiflexion when performing squats. Forty two healthy subjects (21 men, 21 women; 22.5 (4.5) years, 7...
A preliminary clinical prediction model for upper-extremity injury in collegiate baseball: a single-center retrospective study 2013 4968 Context: Evidence-based practice (EBP) has become a point of emphasis in athletic training education and clinical practice. One approach to EBP is utilizing clinical prediction models (CPM) to assist clinicians in the screening, diagnosis, prognosis,...
The influence of attentional focus on neuroplasticity following a seven-day balance training intervention 2017 867 It is well established that focusing on the external effect of one’s movement (an external focus of attention) results in enhanced motor learning and produces superior motor performance compared to focusing inward on the body’s own physical execution...
Varus/valgus and internal/external rotational knee joint stiffness in males and females 2006 2318 "The purpose of this investigation was to establish day to day reliability of varus/valgus and internal/external rotational stiffness measures and then compare stiffnesses between males and females. Twenty healthy college students underwent varus/val...
Effectiveness of cervical spine stabilization during spine boarding of collegiate lacrosse athletes 2006 2812 "This study determined if properly and improperly fitted lacrosse helmets provide adequate stabilization of the head, and therefore the cervical spine, in the spine boarded athlete. A 3 x 3 repeated measures design was used with head to helmet range ...
The relationship of ACL morphometry and structural composition to anterior knee laxity 2016 6424 Greater anterior knee laxity (AKL) has been identified as a risk factor of anterior cruciate ligament (ACL) injury and could be indicative of a weaker ligament. While ACL morphometry and structural composition have the potential to affect ligamentous...
Validation of the thigh stabilization system for a novel multi-planar instrumented knee arthrometer 2019 369 Knee joint laxity characterizes the structural proprieties of the connective tissues and supporting structures within the knee joint. In the past, knee joint laxity has been measured subjectively by clinicians who assess joint integrity through manua...
Estimation of muscle torque impulses and ability to predict high-risk knee joint mechanics during landing maneuvers 2011 4306 This research first examined the validity of net knee joint moment estimations, calculated as the difference between quadriceps and hamstrings torques estimated using either an isometric or angle and action specific sEMG/Torque ratio calculated durin...
Individual muscle thickness of the quadriceps and hamstrings and their relationship with knee extension and flexion strength 2017 520 Strength of the thigh muscles, namely the hamstrings and quadriceps, is a strong determinant of athletic performance and recovery from injury. Thigh strength can be directly assessed using dynamometry or clinical tasks such as jumps and hops, althoug...
The impact of differential knee laxity on brain function/structure and postural control 2020 162 Greater anterior knee laxity (AKL) is known to be a significant predictor of anterior cruciate ligament (ACL) injury. Individuals with high AKL are known to have a proprioception deficit and exhibit compensatory movement patterns. The potential alter...
