The Effects Of Exercise Training On Cognitive Reserve And Cognitive Function In Healthy Older Women, Katie Marie Becofsky Aug 2014

The Effects Of Exercise Training On Cognitive Reserve And Cognitive Function In Healthy Older Women, Katie Marie Becofsky

Theses and Dissertations

Cognitive reserve theory suggests that physical activity may protect individuals from cognitive decline. At the brain level, greater cognitive reserve may manifest as greater neural network efficiency. Our purpose was to investigate 1) whether participation in a 16-week walking program increased brain efficiency, and 2) whether increased brain efficiency correlated with change in fitness and task performance. Our secondary purpose was to investigate whether exercise training improved performance on a battery of cognitive tasks, particularly executive functioning performance. Seventeen healthy but sedentary women aged 60-75 years participated in a supervised walking program; eighteen women served as a non-randomized control group. …


Neural Reactivity To Visual Food Stimuli In The Morning And Evening: An Fmri Study In Women, Travis Daniel Masterson Aug 2014

Neural Reactivity To Visual Food Stimuli In The Morning And Evening: An Fmri Study In Women, Travis Daniel Masterson

Theses and Dissertations

Background: Visual food stimuli have been shown to influence desire to eat and may influence overall energy intake. The purpose of this study was to determine the influence, if any, that time of day has on the neural response to visual food stimuli, as measured by functional magnetic resonance imaging (fMRI). Methods: Using a crossover design, 15 healthy women were scanned using fMRI while presented with low- and high-energy pictures of food, once in the morning (6:30–8:30 am) and once in the evening (5:00–7:00 pm). Diets were identical on both days of the fMRI scans and were verified using weighed …
