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 …
The Effects Of Exercise Pattern And Intensity On The Expression Of Flk-1 And Flt-1 Receptors In The Hippocampus And Cerebellum, Morgan E. Stevenson
The Effects Of Exercise Pattern And Intensity On The Expression Of Flk-1 And Flt-1 Receptors In The Hippocampus And Cerebellum, Morgan E. Stevenson
Theses and Dissertations
Aerobic exercise benefits the body and brain. In the brain, these benefits include neuroprotection and improved cognition. These exercise-induced changes are attributed in part to angiogenesis: the growth of new capillaries from preexisting vessels. One critical factor involved in the regulation of angiogenesis is VEGF and its receptors Flk-1 and Flt-1. Although exercise is generally found to be beneficial, there are wide variations in the exercise regimens used across experiments. This study standardized some of these variations. In this study, rats were either assigned to a voluntary wheel running or a forced wheel running exercise condition. Within each condition, animals …

Spectral Domain-Optical Coherence Tomography For The Assessment Of Cerebrovascular Plasticity, Jacob James Michael Kay
Theses and Dissertations
Vascular pathologies represent the leading causes of mortality worldwide, accounting for 31% of all deaths in 2012. Cerebral hypoxia is a condition that often manifests as a result of these medical conditions. Remarkably, the nervous system has evolved mechanisms to compensate for oxygen deprivation. The dilation of existing vessels and the growth of new blood vessels are two prominent physiological responses to hypoxia, both of which play a critical role in maintaining cerebral homeostasis. More recently, exercise has been shown to induce a mild state of hypoxia in the brain, leading to several robust morphological changes within the cerebrovascular system …
Exercise-Induced Hypoxia, Angiogenesis, And Behavioral Flexibility In The Adult Rat, Kiersten Lee Berggren
Exercise-Induced Hypoxia, Angiogenesis, And Behavioral Flexibility In The Adult Rat, Kiersten Lee Berggren
Theses and Dissertations
Exercise induces a myriad of effects on the brain from the growth of new capillaries and neurons, to improvements in cognitive performance. Additionally, recent research has shown that commencement of an exercise regimen also causes apoptosis. Therefore, it is possible that exercise-induced increases in oxygen demand cause the brain to transiently experience a state of hypoxia. To investigate this hypothesis, we measured protein levels of hypoxia inducible factor 1 alpha (HIF-1α), a transcription factor known to be upregulated in conditions of hypoxia or ischemia, in animals exposed to a single bout of treadmill exercise. After exercise animals were sacrificed at …
