Hashtagging Your Health: Using Psychosocial Variables And Social Media Use To Understand Impression Management And Exercise Behaviors In Women, Caitlyn Hauff
Theses and Dissertations
Our society has become heavily reliant on social media, especially in the health and exercise domain. Social and environmental factors impact females’ body image perceptions and create body image disturbances, yet little research is dedicated to the exploration of how social media, and social comparisons through social media exposure, impact exercise behaviors and body image perceptions in females. Considering Perloff's (2014) theoretical model, the current study explored how the interaction between individual psychosocial variables and social media use predict exercise behaviors and engagement in impression management in women. Using a mixed methodological approach, the specific aims of this study were …
Identifying Gait Deficits In Stroke Patients Using Inertial Sensors, Lauren Benson
Identifying Gait Deficits In Stroke Patients Using Inertial Sensors, Lauren Benson
Theses and Dissertations
Falls remain a significant problem for stroke patients. Tripping, the main cause of falls, occurs when there is insufficient clearance between the foot and ground. Based on an individual’s gait deficits, different joint angles and coordination patterns are necessary to achieve adequate foot clearance during walking. However, gait deficits are typically only quantified in a research or clinical setting, and it would be helpful to use wearable devices – such as accelerometers – to quantify gait disorders in real-world situations. Therefore, the objective of this project was to understand gait characteristics that influence the risk of tripping, and to detect …
The Effects Of Military Style Ruck Marching On Lower Extremity Loading, Daniel N. Poel
The Effects Of Military Style Ruck Marching On Lower Extremity Loading, Daniel N. Poel
Theses and Dissertations
Load carriage while performing prolonged marches may play a role in military overuse injuries. It is known that both external load carriage and muscular fatigue can contribute to increases in ground reaction forces and loading rate and play a role in stress injuries. The purpose of this study is to determine whether or not a prolonged military style ruck march will cause changes in vertical ground reaction force and loading rate. 15 healthy members of the Army ROTC and Army National Guard performed vertical jumps, had ankle dorsiflexion, plantarflexion, inversion and eversion strength measured, and walked across a force plate …
An Examination Of Light Intensity Physical Activity And Health In Older Adults, Whitney A. Welch
An Examination Of Light Intensity Physical Activity And Health In Older Adults, Whitney A. Welch
Theses and Dissertations
Research has begun to quickly emerge on the potential benefit of light intensity physical activity (LPA) to the health of adults. Little is known about LPA, and much of the current LPA research stems from sedentary behavior research. The purpose of this dissertation was to more fully understand, describe, and characterize potential health benefits of LPA by determining the prevalence, patterns, and health benefits of light intensity physical activity in older adults. Three individual studies were completed to address each portion of this purpose. Study 1: Light Intensity Physical Activity and Health in Adults: A Systematic Review. The purpose of …
Investigation Of Neural Mechanisms Of Grip Relaxation, Binal Motawar
Investigation Of Neural Mechanisms Of Grip Relaxation, Binal Motawar
Theses and Dissertations
Neural mechanisms for grip relaxation are relatively unknown and understudied, as compared to mechanisms for grip initiation. Yet, termination of motor activity is as important as initiation in daily function. This knowledge gap presents incomplete understanding of neural control of hand function and its impairment with aging and neurologic disorders. The purpose of this dissertation was to identify and examine neural mechanisms of grip relaxation in healthy young adults, with aging, and in chronic stroke survivors. A series of experiments in healthy young adults showed that the relaxation from a maximum power grip was mediated by increase in the short-interval …
A Study Of The Hydrostatic And Hydrodynamic Properties Of Aeoliscus Straigatus, Jeremy J. Keifenheim
A Study Of The Hydrostatic And Hydrodynamic Properties Of Aeoliscus Straigatus, Jeremy J. Keifenheim
Theses and Dissertations
Aeoliscus strigatus is a highly maneuverable fish found in the Indo-Pacific region. It boasts a unique head down posture and employs median paired fin propulsion to perform precise movements. The need for highly maneuverable underwater AUVs for exploration and testing drove the examination of the hydrostatics and hydrodynamics influencing Aeoliscus. To determine the stability of Aeoliscus the center of gravity and buoyancy were found. Center of gravity was experimentally located using the three plumb line method while center of buoyancy was located using two separate methods. The first method utilized the measured buoyant force, a rigidly mounted fish and a …
Influence Of A Corrective Exercise Training Program On Measures Of Functional Movement Among Active-Duty Firefighters, David James Cornell
Influence Of A Corrective Exercise Training Program On Measures Of Functional Movement Among Active-Duty Firefighters, David James Cornell
Theses and Dissertations
Introduction: Previous research suggests that functional movement quality is related to musculoskeletal injury (MSKI) risk, as well as measures of health and fitness, among the firefighter population. Therefore, if a corrective exercise program could elicit improvements in functional movement quality among firefighters, it may be possible to concomitantly improve health and fitness, as well as decrease MSKI risk, among this cohort population of tactical athletes. Methods: Accordingly, 51 active-duty firefighters were recruited to participate in the pre-intervention (Phase 1) and intervention (Phase 2) portions of the current study. Phase 1 examined the relationship between two different functional movement assessments among …
Foot Kinematics And Neuromuscular Preactivation In Habitual Forefoot And Rearfoot Runners, Rhiannon Seneli
Foot Kinematics And Neuromuscular Preactivation In Habitual Forefoot And Rearfoot Runners, Rhiannon Seneli
Theses and Dissertations
As the rate of running related injuries has failed to decline despite advances in footwear, many researchers have begun focusing on different foot strike patterns possible contribution to injury risk. While many studies have focused on the differences between RFS and FFS running, few have investigated kinematic differences within the distal foot in habitual RFS and FFS runners and have failed to consider mechanical and neuromuscular changes due to fatigue. The purpose of this study, therefore, was to investigate foot kinematics and neuromuscular differences between RFS and FFS runners at the beginning and end of an exhaustive run. Fifteen habitual …
