A Biomechanical Analysis Of Back Squats: Motion Capture, Electromyography, And Musculoskeletal Modeling, Eva Maria Urdiales Maddox
A Biomechanical Analysis Of Back Squats: Motion Capture, Electromyography, And Musculoskeletal Modeling, Eva Maria Urdiales Maddox
Human Movement Studies & Special Education Theses & Dissertations
Previous literature evaluating maximal back squats have failed to identify key components of the study decisions and procedures that would allow for duplication. Firstly, the existence of a sticking region in maximally weighted resistance exercises is frequently discussed and has been described as a force-reduced transition phase between an acceleration phase and a strength phase of a lift. However, the etiology has yet to be agreed upon. Second, Electromyography (EMG) is frequently used to assess muscle activations. However, no best practice for EMG normalization has been proposed. Two methods are commonly implemented for normalizing EMG: a maximum voluntary isometric contraction …
Physical Activity, Social Support, And Health-Related Quality Of Life In Adults With Visual Impairment, Tayah Lynn Otterness
Physical Activity, Social Support, And Health-Related Quality Of Life In Adults With Visual Impairment, Tayah Lynn Otterness
Human Movement Studies & Special Education Theses & Dissertations
The purpose of this study was to examine the relationship between participation in physical activity (PA), social support for exercise, and health-related quality of life (HRQoL) in adults with visual impairments (VI). Due to limited existing literature, this study was used to investigate variables that may impact HRQoL among the specified population. This study used a cross-sectional design and online surveys to determine relationships between the examined variables. Data was collected via Qualtrics Surveying and Google Forms Software. Physical activity was assessed using the International Physical Activity Questionnaire Short Version (IPAQ-SF), a 7-day recall of walking, moderate PA, vigorous PA, …
Utilization Of Finite Element Analysis Techniques For Adolescent Idiopathic Scoliosis Surgical Planning, Michael A. Polanco
Utilization Of Finite Element Analysis Techniques For Adolescent Idiopathic Scoliosis Surgical Planning, Michael A. Polanco
Mechanical & Aerospace Engineering Theses & Dissertations
Adolescent Idiopathic Scoliosis, a three-dimensional deformity of the thoracolumbar spine, affects approximately 1-3% of patients ages 10-18. Surgical correction and treatment of the spinal column is a costly and high-risk task that is consistently complicated by factors such as patient-specific spinal deformities, curve flexibility, and surgeon experience. The following dissertation utilizes finite element analysis to develop a cost-effective, building-block approach by which surgical procedures and kinematic evaluations may be investigated. All studies conducted are based off a volumetric, thoracolumbar finite element (FE) model developed from computer-aided design (CAD) anatomy whose components are kinematically validated with in-vitro data. Spinal ligament stiffness …
The Associations Of Cardiovascular Disease, Physical Activity Intensities, And Measures Of Obesity On Static Balance In Middle-Aged And Older Adults, Hannah Martha Twiddy
The Associations Of Cardiovascular Disease, Physical Activity Intensities, And Measures Of Obesity On Static Balance In Middle-Aged And Older Adults, Hannah Martha Twiddy
Human Movement Studies & Special Education Theses & Dissertations
The burden of falls is widely known in older adults, though less research has targeted middle-aged adults (40-64 years of age), particularly at the population level. The purpose of this dissertation was to explore the roles of cardiovascular disease, physical activity (PA) intensity, and body anthropometrics on balance among middle-aged adults. Study 1 sought to determine if balance was impaired in middle-aged adults with poor ankle-brachial pressure index (ABPI), a marker of cardiovascular disease. Study 2 determined the associations between PA intensity with odds of having good static balance. Study 3 explored how strongly a variety of anthropometric measures, including …
The Relationship Of Strength, Mobility, And Performance Variables On Throwing Speed In Baseball Catchers, Caleigh D. Hall
The Relationship Of Strength, Mobility, And Performance Variables On Throwing Speed In Baseball Catchers, Caleigh D. Hall
Human Movement Studies & Special Education Theses & Dissertations
Baseball is a popular sport worldwide and has thus garnered significant research focus, predominately of pitchers and hitters. However, research involving catchers is scant despite their major influence and consistent presence throughout a game. Therefore, the purpose of this study was to determine the relationship of lower body strength and mobility and performance with throwing speed in baseball catchers. We hypothesized that strength and mobility would have a positive relationship with ball speed, peak power generated while rising out of the squat position would be positively related to ball speed, shorter ascent time would be inversely related to ball speed, …
