Outclimbing Cognitive Decline: Age, Western Diet, Resistance Exercise, And The Brain., Leila Dzinic

Electronic Thesis and Dissertation Repository

Increased age and obesity diminish motivation, perseverance, and spatial memory function. Aerobic exercise interventions have successfully rescued some of these processes. However, in older and heavier populations aerobic exercise is not as sustainable due to high risk of injury. Resistance exercise consists of physical activity where maximum oxygen consumption is not increased and has been proposed as a safe and effective intervention for this population. Here, we used touchscreen-based cognitive testing to elucidate the influence of resistance exercise on motivation and spatial memory in aged, diet-induced obese mice, using a water restriction procedure I develop in Chapter 2. Mice underwent …

Results: In 2015, 35.66% of Canadians aged 6 to 17 met sugar intake guidelines. Compared to 2004, in 2015 intake of fruit and vegetables was higher, while sugar and caloric intake was lower. Sedentary activity, …

The Effects Of A Six Month Nutrition Intervention On Diet Quality In Persons With Or At Risk For The Metabolic Syndrome, Rebecca Horne

Electronic Thesis and Dissertation Repository

One quarter of the world’s population is thought to have the metabolic syndrome, and first line treatments include dietary strategies for weight loss. Restrictive diet interventions commonly used in research appear to lack long-term sustainability; therefore, other approaches are warranted. The Canadian Healthy Eating Index (CHEI) was used as a framework and outcome measure for a 6-month ad-libitum diet quality intervention that assessed diet quality and key risk factors of the syndrome. Participants (n=23) were randomized to the nutrition program (n=16) or usual care (control) (n=7). Post intervention, CHEI scores increased by 9.1 and 3.4 points intervention and control, respectively …
