Correlation Of Shoulder And Elbow Kinetics With Ball Velocity In College Baseball Pitchers, Eric Post

Theses and Dissertations

Specific injuries at the elbow and glenohumeral joints have been linked to several kinetic variables that occur throughout the throwing motion. Ulnar collateral ligament (UCL) sprains have been linked to excessive elbow valgus and shoulder external rotation torques occurring during the late-cocking phase of throwing. Shoulder external rotation torque during the late arm-cocking phase and shoulder distraction forces during the deceleration phase contribute to tears of the labrum. Additionally, it is believed that the peak distraction force generated during the arm deceleration phase also contributes to SLAP tears and rotator cuff pathologies. Very little research has been done to directly …

The Effects Of Static Stretching Versus Dynamic Stretching On Lower Extremity Joint Range Of Motion, Static Balance, And Dynamic Balance, Wenqing Wang

Theses and Dissertations

The purpose of this study was to examine the effects of static stretching (SS) versus dynamic stretching (SS) on lower extremity joint range of motion (ROM), static balance, and dynamic balance. Fifteen active subjects with tight hamstring and calf muscles participated. Hip flexion and knee extension ROM angle was measured using a fluid inclinometer. A closed-chain method of measuring ankle dorsiflexion ROM was used. Static balance was assessed in single-leg stance on a force plate using the time-to-boundary (TTB) measurement. The Star Excursion Balance Test (SEBT) was used to assess dynamic balance in three directions. These measurements were assessed before …

Examining Mediators To Physical Activity As A Link To Interventional Efforts Aimed At Increasing Activity Levels And Improving Physical Functioning In Older Adults, Christopher Dondzila

Theses and Dissertations

The number of older adults living in the United States is growing at an increasingly rapid rate, and is host to a high prevalence of chronic diseases and physical impairments. Physical activity and exercise have been shown to be beneficial in impacting such conditions, yet the majority of older adults remain inactive. The purpose of this dissertation was to employ a sequence of studies to investigate mediators to physical activity, leading to an intervention to increase activity and promote health.

The purpose of Project VOICE was to examine whether awareness and utilization of community resources to promote physical activity and …

Investigation Of Web-Based Motivational Interviewing To Increase Physical Activity Participation Among Adults, Sasha Karnes

Theses and Dissertations

Interventions to enhance physical activity (PA) participation are needed given the high prevalence of under-activity and inactivity (CDC, 2001) and related occurrence of negative health consequences among the general adult population (Kung, Hoyert, Xu, & Murphy, 2008). Preliminary support for a therapeutic technique called Motivational Interviewing (MI) suggests promise for application to enhance PA participation (Burke, Arkowitz, & Menchola, 2003). Given the need for interventions to enhance PA and the preliminary support for MI as an intervention to increase PA, the aims of the current study were to: (a) determine if web-based MI is effective in enhancing PA participation, and …

The Effect Of Cancer Cachexia Severity And Eccentric Muscle Contractions On Selected Myofiber Metabolic Properties In Mouse Skeletal Muscle, Joshua Earl Mangum

Theses and Dissertations

Cancer cachexia is a complex syndrome that induces skeletal muscle wasting and dysregulation of skeletal muscle metabolism. Alterations in area of myofibers and myofiber metabolic properties can significantly impact the function of skeletal muscle. The purpose of this study was to examine the effect of cachexia severity and resistance exercise training on frequency and area of selected myofiber metabolic characteristics during cachexia-induced myofiber atrophy. Male ApcMin/+ (Min) mice were studied during the progression of cachexia (16-20 weeks of age) and stratified into groups based on the severity of cachexia. For the second study, male Min mice performed resistance exercise (RE) …
