The Effects Of A Three-Hour, After School Bout Of Sedentary Vs Active Behavior On Reward And Cognitive Control Activation In 8- To 9-Year-Old Children: A Randomized Crossover Study, Mary Linn White
Theses and Dissertations
PURPOSE: To compare the effects of after-school sedentary versus active play on activation in the reward and cognitive control regions of the brain to pictures of high- and low-calorie foods. METHODS: 32 children (12 girls, 20 boys; age 8.7 ± 0.5 years; height 137.9 ± 6.9 cm; weight 32.4 ± 6.2 kg) participated in a randomized crossover study with counterbalanced treatment conditions. Conditions took place on separate days after school and included three hours of active or sedentary play. After each condition, neural activation in reward and cognitive control regions of the brain were assessed using functional magnetic resonance imaging …
Neural Activation In Blood-Flow-Restricted Versus Non-Blood-Flow-Restricted Exercise: An Fmri Study, Tiffany Dawn Devries
Neural Activation In Blood-Flow-Restricted Versus Non-Blood-Flow-Restricted Exercise: An Fmri Study, Tiffany Dawn Devries
Theses and Dissertations
Functional magnetic resonance imaging (fMRI) can be used to track neural activation in the brain during functional activities. The purpose of this study was to investigate brain neural responses to blood flow restricted (BFR) versus control handgrip exercise. Using a randomized crossover design, 25 subjects (12 males, 13 females) completed handgrip exercises during two conditions: BFR vs. control. To familiarize participants with the exercise conditions, one week prior to MRI scanning participants completed each exercise condition once on separate days, with 72 hours between days. The following week fMRI scans were performed at the same time of day, separated by …
Neural Reactivity To Visual Food Stimuli In The Morning And Evening: An Fmri Study In Women, Travis Daniel Masterson
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 …
