Effects Of Home-Based High-Intensity Interval Training Versus Continuous Walking On Cognition In Overweight And Obese Women, Kelsey C. Bourbeau Dec 2022

Effects Of Home-Based High-Intensity Interval Training Versus Continuous Walking On Cognition In Overweight And Obese Women, Kelsey C. Bourbeau

Health, Exercise, and Sports Sciences ETDs

Objective: The purpose of the present study was to determine whether six weeks of home-based high-intensity interval training versus six weeks of moderate-intensity walking improves cognition, depression, and anxiety in women that are overweight or obese. Design: A randomized control trial design. Subjects: Twelve sedentary women characterized as overweight or obese were randomized into either a six-week home-based high-intensity interval training (HIIT, n = 6, 26.6 ± 8.9 years, 37.4 ± 4.9% body fat) group or a six-week moderate-intensity walking (Walk, n = 6, 22.5 ± 3.7 years, 40.2 ± 4.1% body fat) group. Main Measures: Pre- and post-intervention, participants …

Postexercise Executive Function Benefits And Cerebral Blood Flow: In The Lab And At Home, Benjamin Tari Nov 2022

Postexercise Executive Function Benefits And Cerebral Blood Flow: In The Lab And At Home, Benjamin Tari

Electronic Thesis and Dissertation Repository

A single bout of aerobic exercise improves executive function; however, the mechanism, or mechanisms, supporting this improvement remain unclear. One candidate mechanism is an exercise-mediated increase in cerebral blood flow (CBF) that enhances the efficiency of executive-related frontoparietal networks. To evaluate the link between exercise, CBF and executive function, three separate experiments were conducted. In the first study, separate 10-min sessions of moderate-to-heavy-intensity aerobic exercise, and a hypercapnic environment (i.e., 5% CO2) were implemented. The hypercapnic condition was included because it increases CBF independent of the metabolic demands of exercise. The second study investigated whether exercise intensity-specific changes …

Linking Spinal Cord Circuits With Upper Limb Sensorimotor Control In Adults With Cerebral Palsy, Saihari Dukkipati May 2022

Linking Spinal Cord Circuits With Upper Limb Sensorimotor Control In Adults With Cerebral Palsy, Saihari Dukkipati

Theses & Dissertations

Cerebral palsy (CP) is the most common neurological disorder originating in childhood, but most of the people living with CP are currently adults. While people with CP continue to get older, the amount of research focused on adults has been rather limited. The early childhood insults leading to CP are thought to originate in the brain, but the effects on the entire neuromuscular system across the lifespan have only recently started to be explored. Of note, recent neuroimaging evidence suggests that the cervical spinal cord structure is atypical in adults with CP. However, it is largely unclear how the neurophysiological …

The Effects Of Acute Exercise Intensity On Retrieval-Induced Forgetting, Geoffrey Reliquias May 2022

The Effects Of Acute Exercise Intensity On Retrieval-Induced Forgetting, Geoffrey Reliquias

Honors Theses

Previous research has indicated that aspects of cognitive inhibition may be enhanced after engaging in acute exercise. Notably, cognitive inhibition has been theorized as a potential mechanism for a form of active forgetting known as retrieval-induced forgetting (RIF). Given that cognitive inhibition may explain the RIF phenomenon, and is also influenced by exercise, it is plausible that acute exercise may directly influence RIF. To our knowledge, only one study has examined whether acute exercise has an effect on RIF. The findings of that study did not find a statistically significant effect for RIF; however, we believe that the rather small …

Frailty And Neurocognition In Prostate Cancer, Lindsey Hanson May 2022

Frailty And Neurocognition In Prostate Cancer, Lindsey Hanson

Theses & Dissertations

Prostate cancer (PCa) treatment often leads to distressing side effects ranging from muscle loss, physical inactivity, and fatigue to cancer associated cognitive decline (CACD). Evidence suggests that men treated with androgen deprivation therapy (ADT) may have a specifically high risk of CACD, partially due to increased frailty. However, the current literature on cognitive effects of ADT is equivocal. Therefore, the primary objectives of this study were to (1) compare cognitive function, physical activity (PA), and fitness in men receiving ADT, men scheduled to receive radiation, and men under active surveillance for PCa; (2) examine changes in cognitive performance and PA …

Effects Of Acute Exercise Intensity On Memory: Considerations Of Timing And Aerobic Endurance, William Meyers, Caroline Loeb, Mary Collins West, Bailey Bass Apr 2022

Effects Of Acute Exercise Intensity On Memory: Considerations Of Timing And Aerobic Endurance, William Meyers, Caroline Loeb, Mary Collins West, Bailey Bass

Honors Theses

The primary objective of this study was to find the optimal acute exercise intensity and post-exercise recovery time to enhance memory retention. A secondary objective of study was to evaluate the influence of aerobic endurance on memory and whether endurance capacity interacts with exercise intensity and post-exercise recovery period to influence memory performance. Participants were 54 undergraduate and graduate students at the University of Mississippi, with an age range of 18-23 years. Participants completed 13 visits in total. The first visit evaluated their aerobic endurance, with the remaining 12 visits including a 3 (Intensity: Control, Moderate, Vigorous) by 4 (Post-Exercise …

Age-Related Changes In Corticospinal Drive During Locomotor Adaptation, Sumire D. Sato Mar 2022

Age-Related Changes In Corticospinal Drive During Locomotor Adaptation, Sumire D. Sato

Doctoral Dissertations

During activities of daily living, locomotor patterns must be continuously adapted according to changes in our body (e.g., bodily injuries, fatigue) and to the changing environment (e.g., walking surface). Plasticity of spinal networks and supraspinal centers, including the cerebellum and cerebral cortex, have been shown to play important roles in human locomotor adaptation. However, the neural control of locomotion and the ability to adapt locomotor patterns are altered in older adults, which may limit activities of daily living and increase fall-related injuries in the elderly population. My dissertation project is focused on understanding the role of corticospinal drive during split-belt …

Beginnings, Elizabeth Becker Jan 2022

Beginnings, Elizabeth Becker

Dance (MFA) Theses

Researcher Elizabeth Becker uses personal experiences of pregnancy alongside scholarly research on the developmental movement patterns of the human embryo, fetus, and newborn’s first year of life to explore the multiplicity of these movement patterns within and outside the womb. Becker explores the relationship between the fertilization, germinal, embryonic, and fetal stages in relation to a newborn and its mother. These movement patterns within the beginning stages of life are valuable to research because they simulate neurodevelopmental patterns, which help wire the central nervous system in early childhood. These movements also help lay the foundation for sensory-motor development and life-long …
