Establishing The Microcrustacean Daphnia As A Model System For Research On Aging, Charles Andrew Shumpert
Establishing The Microcrustacean Daphnia As A Model System For Research On Aging, Charles Andrew Shumpert
Theses and Dissertations
Aging is a ubiquitous process pertaining to all biological systems around the planet. Although much has been learned from studies so far on the molecular mechanisms that lead to aging, a complete understanding of a healthy life span and longevity still eludes us. In this dissertation, we will examine the use of a freshwater microcrustacean Daphnia as a model system for studies on the biology of aging. The Introduction chapter presents a review of the general molecular alterations associated with cellular and organismal aging, and discusses the core model organisms currently used to study the aging process. The introduction chapter …
The Effects Of Exercise Training On Cognitive Reserve And Cognitive Function In Healthy Older Women, Katie Marie Becofsky
The Effects Of Exercise Training On Cognitive Reserve And Cognitive Function In Healthy Older Women, Katie Marie Becofsky
Theses and Dissertations
Cognitive reserve theory suggests that physical activity may protect individuals from cognitive decline. At the brain level, greater cognitive reserve may manifest as greater neural network efficiency. Our purpose was to investigate 1) whether participation in a 16-week walking program increased brain efficiency, and 2) whether increased brain efficiency correlated with change in fitness and task performance. Our secondary purpose was to investigate whether exercise training improved performance on a battery of cognitive tasks, particularly executive functioning performance. Seventeen healthy but sedentary women aged 60-75 years participated in a supervised walking program; eighteen women served as a non-randomized control group. …
The Effects Of Arthritis Foundation’S “Walk With Ease” Program On Cognitive Function, Ryan S. Falck
The Effects Of Arthritis Foundation’S “Walk With Ease” Program On Cognitive Function, Ryan S. Falck
Theses and Dissertations
Physical activity (PA) is believed to improve cognitive function, particularly executive function, in older adults. However, few interventions in community settings have been performed to improve executive function through PA. The purpose of this study was to determine the effects of a community-based walking program on executive function in older adults (60+ years). Older adults from senior centers throughout Lexington County, SC were recruited for participation in this intervention. Exclusion criteria included currently exercising >30 minutes and exercising ≥2x/week or scoring ≤25 on the Mini-Mental State Exam. The intervention consisted of an evidenced-based community walking program, the Arthritis Foundation ’ …
