Modifiable And Non-Modifiable Factors Related To The Macular Pigment Optical Density (Mpod) In A Population Of College-Aged Adults, Genesis Gisselle Guerra Gaitan

LSU Master's Theses

Age-related macular degeneration (AMD) is one of the leading causes of blindness among the elderly worldwide. Retinal problems, specifically in the macula, hold potential for development of AMD. Macular pigment optical density (MPOD) gives a measure of the thickness of the macula and therefore health of the macula. Some of the populations at risk for development of AMD include being white, female, and having light eye color. Factors related to the development of the disease have been divided into modifiable and non-modifiable; non-modifiable include a genetic predisposition. Control of modifiable factors, including body mass index (BMI) and diet [dietary intake …

Physical Activity And Associated Energy Intake In Undergraduate College Students, Erin Marie Fejes

Theses and Dissertations

Background: College students often develop unhealthy eating habits. Poor eating habits can lead to chronic disease.

Methods: Energy intake and physical activity data from 35 undergraduate students enrolled in a 100-level kinesiology class were recorded and analyzed. Energy intake data was self-reported, while physical activity data was recorded via an activity tracker.

Results: Data points were analyzed twice: each day separately and as averages for each participant. When analyzed as averages, grams of total fat and grams of carbohydrate were the most significantly correlated with minutes of moderate to vigorous+ physical activity (both p<0.01). When analyzed by day, grams of protein, total fat, saturated fat, carbohydrate, sugar, and fiber were all found to be significantly correlated with minutes of moderate to vigorous physical activity to the p≤0.01 level.

Behaviour Change Intervention Strategies To Prevent Excessive Gestational Weight Gain In Pregnant Women Using A Nutrition And Exercise Lifestyle Intervention Program (Nelip), Karishma Hosein

Electronic Thesis and Dissertation Repository

Maternal obesity and excessive gestational weight gain (EGWG) are associated with adverse maternal and fetal outcomes. To evaluate the effectiveness of different behaviour change intervention strategies, it was hypothesized that the introduction of a single behaviour change, followed by a second, would be more effective at preventing early and total EGWG in pregnant women compared to the early simultaneous introduction of both behaviour changes. Eighteen pregnant women were block randomized into one of 3 Nutrition and Exercise Lifestyle Intervention Program (NELIP) strategies (full NELIP, Nutrition followed by Exercise N+E, Exercise followed by Nutrition E+N) and were followed at weekly face-to-face …

The Effects Of Dietary Intake On Fuel Metabolism During Aerobic Capacity Exercise, Taylor Lynn Stephenson

Theses and Dissertations

In order to produce mechanical energy through muscular activity, the body must oxidize chemical energy, carbohydrate, fat, or protein through metabolic processes, which then results in the production of ATP as mechanical energy through exercise. Total body metabolism, specifically skeletal muscle depends on factors such as the intensity and duration of exercise, substrate availability, and Training status. During exercise at low intensities (25% of VO2 max) fat is the primary macronutrient that is oxidized for energy. As the exercise intensity progresses, (65% of VO2 max) there is an alteration in skeletal muscle utilization, which results in mainly the use of …
