An Examination Of The Neuropsychological Construct Executive Function And How It May Be Impacted By Cognitive And Exercise Interventions, Erica Schmidt

All ETDs from UAB

Background: There is a growing body of literature supporting the beneficial effects of cognitive training and exercise training on executive function (EF) in older adults. More recently, evidence is amassing that interventions which combine cognitive and physical activity, for example, exergames, may confer even greater cognitive benefits. Comparison of EF interventions for older adults requires more investigation and would benefit from improved operationalization of the EF construct and better understanding of factors which predict baseline EF in older adults. Methods and Results: Fifty-seven sedentary, non-gamer, community dwelling older adults were randomly assigned to one of three intervention groups (computerized cognitive …

Physical function is a known predictor of morbidity and mortality, with initial evidence indicating that presurgical exercise is associated with fewer postsurgical complications and shorter hospitalization. The aim was to determine the feasibility of a supervised presurgical exercise program for prostate cancer (PCa) patients scheduled for prostatectomy.

Methods:

Ten men (68+6.4 years old) with localized PCa undertook a 6-week resistance and aerobic exercise program prior surgery. Training was undertaken twice weekly and patients were assessed at baseline, presurgery, and …

The Influence Of Plant- And Animal-Based Diets On Testosterone And Lean Body Mass Is Male Rats, Damien Christopher Moore

Electronic Theses and Dissertations Archive

Background: It is commonly believed but unproven that plant-based diets result in low circulating testosterone, with minimal gains in lean body mass (LBM). Methods: Long-Evans rats (N=28) were assigned to experimental diets with either plant (PD) or animal (AD) protein sources. Animals were further divided into two additional conditions without and with exercise. Animals were fed ad libitum for 3 months and at the end of month three blood was collected for measurement of testosterone and estradiol concentrations. Dual x-ray absorptiometry assessed body composition. Results: Neither blood testosterone concentrations nor LBM differed between rats fed the PD or AD. Conclusion: …

The Effect Of Sleep Restriction On Coagulation And Fibrinolysis After Heavy Exercise, Paul A. Roberson

Masters Theses, 2010-2019

Introduction: Research has shown exercise elicits a hemostatic response affecting coagulation and fibrinolysis. Furthermore, prior research has determined circadian fluctuations exist where clotting potential increases in the morning as a result of increased PAI-1 and decreased tPA which is further exacerbated by exercise. These circadian fluctuations and exercise responses have the potential to be accentuated by poor sleep. The purpose of this study is to determine the effects of sleep restriction on tPA activity, PAI-1 activity, and Factor VIII antigen activity (FVIII) while resting and after exercise.

Methods: 7 Subjects underwent two similar exercises sessions (EX). EX1 occurred in the …

Association Between Polymorphisms Associated With Major Depression, Cognitive Function, And Stress Regulation And Telomere Length In Older Community-Dwelling Adults And In Older Competitive Athletes, Cynthia Elizabeth Perry

Theses and Dissertations

Many factors detrimental to healthy aging have been proposed including depression, stress, cognitive decline, and telomere shortening. Of specific interest are the genetic factors that may contribute to these factors and subsequently lead to accelerated telomere shortening and aging, namely the Bcl1, 5-HT, DRD2, and ApoE polymorphisms. We sought to: 1) further clarify the role of depression, stress tolerance, and cognitive decline in aging by examining the effect of associated polymorphisms (Bcl1, 5-HT, DRD2, and ApoE) on telomere length in two samples of older adults and 2) determine the difference in absolute telomere length between the two groups. We examined …

Physical Activity And Cardiometabolic Risk Factors Among African American Women Residing In The Southeastern United States, Felicia Jenkins

MUSC Theses and Dissertations

Cardiometabolic risk (CMR) refers to an increased risk of developing cardiovascular disease (CVD) or diabetes, two of the leading causes of death in the United States. CMR factors include elevated glucose, blood pressure, and lipids. Lifestyle factors including physical inactivity, smoking, and poor dietary habits such as low fruit/vegetable consumption also contribute to CMR. Notably, African American women (AAW) have a high rate for several CMR factors including obesity, physical inactivity, and hypertension. Furthermore, AAW are an understudied population in research focusing on PA health promotion and studies examining PA associations with CMR. The aims of this dissertation study were …

A Qualitative Pilot Study Of Aging Women’S Physical Activity Experiences In One University Fitness And Wellness Center, Alexis Hobbs

Online Theses and Dissertations

Physical inactivity is one of the driving risk factors for developing health problems such as obesity, diabetes, and cardiovascular diseases (World Health Organization, 2003). The prevalence of these diseases increases with the aging process, which renders participation in physical activity crucial among the aging population. There is strong evidence that physical activity reduces the risk of these health disparities and disabilities (Young & Dinan, 2005), however despite these well-documented benefits, aging women still remain sedentary. This study examined the phenomenon of women 55 years of age or older and their lived experiences of participating in physical activity within a university …

The Effects Of External Focus Of Attention Exercise Rehabilitation On Dual Task Walking In Parkinson's Disease, Eric N. Beck

Theses and Dissertations (Comprehensive)

Parkinson’s disease impairs control of well-learned movements, and therefore, individuals with Parkinson’s disease are forced to walk with greater conscious control. This causes difficulties while walking and completing a secondary task simultaneously (dual tasking), in that distractions from conscious control of walking increase the risk of falls and injury. Although, attention-based exercise may be a potential avenue to decrease the demands associated with walking in Parkinson’s disease. For example, an external focus of attention (on manipulated objects) has been found to recruit the networks that are important for walking with little conscious control (automatic control networks). In contrast, an internal …

Aging is usually accompanied by a significant reduction in muscle mass and force. To determine the relative contribution of inactivity and aging per se to this decay, we compared muscle function and structure in (a) male participants belonging to a group of well-trained seniors (average of 70 years) who exercised regularly in their previous 30 years and (b) age-matched healthy sedentary seniors with (c) active young men (average of 27 years). The results collected show that relative to their sedentary cohorts, muscle from senior sportsmen have: (a) greater maximal isometric force and function, (b) better preserved fiber morphology and ultrastructure …

The Effect Of Training Older Adults In Tai Chi And Compensatory Stepping On Balance Control, Hannah L. Moore Miss

Theses and Dissertations (Comprehensive)

Abstract

Introduction: In Canadian society, there is a growing prevalence of older adults and one of the main problems facing this generation today is the risk of falling. Tai Chi (TC) is a martial art that has demonstrated improvements in balance control. It uses a series of fluid movements that engage head, neck and trunk rotation while simultaneously reducing base of support. In addition, it has been demonstrated that training older adults by administering unpredictable perturbations to challenge balance better equips them to react successfully in response to balance perturbations. This study aims to determine the potential balance specific benefits …

Exercise Motivations Of Older Adults, Laura J. Attaway

All Master's Theses

This study examined and compared activity levels and motives in 103 older (over 50 years of age) competitive athletes (CA) and non-competitive fitness exercisers (NCF). The findings indicate that the CA group was significantly higher in the motives of enjoyment, competition, and social recognition. Ranking of the strength of the motivation factors for each group indicated that enjoyment was the strongest motivating factor for both groups, health ranked high for both groups, and social recognition ranked lowest in both groups. Findings related to rankings were not tested for significance, so are more tentative.

The Influence Of The Initiation Of A Graded Exercise Protocol On Dynamic Postural Stability Following A Concussion, Lauryn Hunter

College of Graduate Studies: Theses & Dissertations

Current post-concussion assessment tools may lack sensitivity in identifying recovery. Athletes demonstrating decreased postural control may have an increased likelihood of suffering sports-related injury. Exercise has been shown to briefly alter static postural control and the visual contribution to static postural stability deteriorates with moderate intensity exercise. Gait variability, defined as the fluctuation in gait characteristic between steps, is a sensitive measure of postural stability in populations with higher level gait disorders. Objective: The purpose of this study was to examine the influence of a progressive exertional return-to-play program on dynamic postural stability following a concussion. Design: Prospective longitudinal. Setting: …

In this study, I used focus groups and interviews to collect qualitative data on five H-NORC attributes: (1) economic policies that benefit seniors; (2) types of transportation support for seniors; (3) neighborhood design for physical activity; (4) opportunities for social integration and sense of belonging; and (5) health …

Adl-Specific Versus Standard Aquatic Exercise In Older Persons, David A. Edwards

Open Access Dissertations

With aging there is a decrease in a person’s ability to perform activities of daily living (ADL) which may be most effectively addressed using training patterns that are biomechanically similar to ADL. Since aquatic exercise offers the opportunity to provide resistance with a high level of safety, the pool may afford the ideal environment for ADL-specific training in an aging population. Purpose: The purpose of this investigation was to compare a traditional aquatic exercise program (TRAD) to an aquatic program tailored to target ADL (ADLspec). Methods: Eighteen independently living individuals (68.7 + 7.5 years) were randomly assigned to a TRAD …
