Post-Exercise And Post-Recovery Blood Lactate In Peripheral Arterial Disease, Rebecca Kate Roderick Dec 2013

Post-Exercise And Post-Recovery Blood Lactate In Peripheral Arterial Disease, Rebecca Kate Roderick

Theses and Dissertations

The purpose of this study was to observe how the presence of peripheral arterial disease affects the level of post-exercise blood lactate and post-recovery blood lactate during and following the six-minute walk test (6MWT). The 6MWT was administered to 49 participants (33 classified as Non-PAD and 16 classified as PAD) over the age of 50 with no uncontrolled cardiovascular or metabolic diseases or a cardiovascular event in the previous 6 months. Results demonstrated that no significant statistical difference exists between the presence of PAD and resting blood lactate (F = 0.86, p = .36), post-exercise blood lactate (F= 0.48, p ...


Evaluation Of Shake Weight Protocol In Senior Populations, Isaac F. Cook Dec 2013

Evaluation Of Shake Weight Protocol In Senior Populations, Isaac F. Cook

Theses and Dissertations

The Shake Weight® (SW®) is designed to improve muscular fitness in a quick and inexpensive way. This study aimed to determine if the SW® was an effective tool at improving muscular fitness, body composition, and bone mineral density (BMD) in post-menopausal women. Participants were 17 healthy, post-menopausal women from aMidwestern University and divided into two training (SW® and HIT) interventions that lasted 10 weeks. HIT participants performed three sets of 8 repetitions at 80% of their estimated 1RM for the chest press, leg press, lat pulldown, and seated row. SW® participants performed the exercises prescribed by the SW® manufacturer. Changes ...


The Interactive Effects Of Multiple Stressors On Lithobates Catesbeianus And Anaxyrus Americanus, Matthew Kyle Holden Aug 2013

The Interactive Effects Of Multiple Stressors On Lithobates Catesbeianus And Anaxyrus Americanus, Matthew Kyle Holden

Theses and Dissertations

Amphibian populations worldwide have experienced dramatic declines, and many species have already become locally, regionally, or globally extirpated with thousands more being threatened with extinction. These declines have occurred more rapidly in amphibians than any other group of vertebrates, which is especially concerning to scientists because amphibians serve as indicator species of overall environmental health. Major causes for amphibian declines are discussed in Chapter 1 and include: habitat modification and destruction, commercial over-exploitation, introduced species, environmental contaminants, global climate change, and infectious diseases.

Chapter 2 discusses the major research aspects of the thesis by examining the interactive effects of multiple ...


Evaluating Economic And Environmental Impacts Of Changing Herd Sire Genetics On Arkansas Cow-Calf Operations, Daniel Keeton Aug 2013

Evaluating Economic And Environmental Impacts Of Changing Herd Sire Genetics On Arkansas Cow-Calf Operations, Daniel Keeton

Theses and Dissertations

This research looks at impacts of changing sires, and thus bull genetics, on cow-calf operations of varying land and herd sizes in the state of Arkansas. A 2012 Across-Breed EPD table, adjusted to the Angus breed, was used to estimate breed sire effects on birth weight and weaning weight of the herd's offspring (Kuehn and Thallman 2012a). Together with modified animal performance, the use of 2012 and most recent five- and ten- year Arkansas state average prices, allowed the evaluation of changing herd sires by accounting for breed type and hide color differences in prices. Using a spreadsheet tool ...


The Impact Of Parent Education On Parental Feeding Practices, Larra Kolby Brawley Aug 2013

The Impact Of Parent Education On Parental Feeding Practices, Larra Kolby Brawley

Theses and Dissertations

This research looked at the potential impact that parent education may have on the feeding practices of parents of young children. Since eating behaviors are a national concern for both children and adults, it's important to examine how we can create not just healthier children but, as a result, healthier adults. This study utilized an intervention that was an adapted version of a healthy eating curriculum created by Sesame Workshop and the California WIC association with the intention of improving parental feeding practices through a behavior-based approach. Previous research with this curriculum has addressed only low-income populations, with a ...


Effects Of Using Canola Meal As A Protein Source In Broiler Diets, Charles Danny Bradley Jr May 2013

Effects Of Using Canola Meal As A Protein Source In Broiler Diets, Charles Danny Bradley Jr

Theses and Dissertations

Six experiments were conducted to evaluate the response of broilers fed canola meal. Experiment 1 assessed performance and carcass yields when broilers were fed various combinations of canola and soybean meal in nutritionally balanced diets based on digestible amino acid values. The results suggested that canola meal can be used in isocaloric diets as a partial replacement for Soybean meal.

Experiment 2 assessed broiler performance and carcass yields when using various levels of canola meal in broiler diets with a constant level of supplemental poultry oil. The resulting data suggested when diets are formulated with a constant level of supplemental ...
