Sustainability Practices In Aquaculture: Using Algae Turf Scrubber Biomass To Raise Black Soldier Flies As An Alternative Feed In Blue Tilapia, Oreochromis Aureus, Culture, Michelle C. Lowery

Electronic Theses and Dissertations

Since the 1980s, non-algal aquaculture has grown to encompass 49% of all seafood production in response to a growing human population and increased seafood demand (FAO, 2022). Hurdles exist to aquaculture sustainability, including dependence on wild sourced fishmeal (FM) and the impacts wastewater discharge. It takes 4-5 tons of wild forage fish to produce one ton of dry FM (Miles and Chapman, 2006) and as aquaculture is primarily conducted in earthen ponds and public open water bodies (FAO, 2022), finfish culture can have a high impact on the surrounding environment by discharging excess nutrients. This study used algae turf scrubber …

Healthfulness Of Fast-Food And Full-Service Restaurants In 16 Georgia Counties After Mandatory Menu Labeling, Janani Rajbhandari-Thapa, Donglan Zhang, Nicole Katapodis, Dana Alvin, Melanie Andrews

Journal of the Georgia Public Health Association

Background: Despite that the effect of menu labeling on consumer choices has been studied, there are gaps in the research on the healthfulness of the restaurant food environment post-mandatory menu labeling, specifically in the Southern United States. This study aims to assess the healthfulness of fast-food and full-service chain restaurant environments after compliance with mandatory menu labeling.

Methods: The healthfulness of 46 representative fast-food and full-service chain restaurants in 16 Georgia counties was examined using the Nutritional Environment Measures in Restaurants (NEMS-R) survey. The scores were compared between full-service and fast-food restaurants using t-tests across several healthfulness measures such as …

The Effects Of Beetroot Juice On Vo2max And Blood Pressure During Submaximal Exercise, Jose M. Perez

Electronic Theses and Dissertations

Supplementation with beetroot juice (BR) has been shown to reduce blood pressure (BP) at rest and improve several performance parameters during submaximal and maximal exercise. BR effects on BP during submaximal exercise have not been investigated. Furthermore, the effects of BR on VO₂max are inconclusive. The purpose of this study was to investigate the effects of BR on VO₂max and BP during submaximal exercise. 20 healthy, recreationally trained volunteers (age 21.8±2.35 years, weight 75.10±10.62 kg, height 177.4±6.39 cm) participated in this study, which had a double-blind placebo controlled randomized crossover design. Participants began supplementation with either …

Female Natural Bodybuilding Competition Preparation: A 6-Week Case Study, Samantha G. Gwazdauskas

Electronic Theses and Dissertations

Bodybuilding is unlike any other sport. Competitors are judged on appearance rather than performance, where muscle size and definition are keys to achieving success. This case study tracked four, drug-free, female bodybuilders for 6-weeks leading up to their competitions. The purpose of this project was to examine the physiological and psychological experiences of female bodybuilders as they prepare for competition. Each competitor reported for testing at three occasions to evaluate cardiovascular measures, body composition, resting metabolic rate, performance measures of strength, power, muscular endurance, and maximal oxygen consumption, mood state, social physique anxiety, and overall experience. Each subject in this …

Effects Of Beta-Alanine Supplementation And High Intensity Interval Training Among Recreationally Active Females, Mary E. Yarbrough

Electronic Theses and Dissertations

Beta-alanine is a non-essential amino acid that when combined with L-histidine forms the dipeptide carnosine. Recent research has shown that supplementary intake of beta-alanine can substantially increase carnosine content in muscle fibers and has been associated with attenuating fatigue and enhancing high intensity exercise performance. The aim of this study was to examine the effects of 4 weeks of beta-alanine supplementation combined with high intensity interval training (HIIT) on indices of aerobic and anaerobic performance, rowing performance, and body composition. Twenty-one recreationally active females (22.2 ± 2.2 yrs.) participated in a double blind, placebo controlled study and were randomly assigned …
