Predictors Of Adl Disability In Culturally Diverse Older Adults, Fernanda Holton

LSU Master's Theses

Almost 42% of adults over 65 years of age live with at least one disability. Further, people of lower socioeconomic status and Blacks have greater risks for disability than Whites and individuals at higher socioeconomic status. The consequences of disability include loss of independence, decreased quality of life, increased chances of depression, consumption of health care services, and institutionalization. The purpose of this study was to utilize the disablement process framework to examine the contribution of physical function, dyspnea, and pain to disability in activities-of-daily-living (ADL) in culturally diverse older adults (i.e., diverse according to race, income, and education). Participants …

Psychological Correlates Of Exercise Behavior Among Adolescents, Kevin C. Paul

LSU Master's Theses

According to the 2003 Youth Risk Behavior Surveillance Survey, 33% of youth in grades 9-12 participated in an insufficient amount of vigorous and moderate physical activity (PA), and 11% reported no vigorous and moderate PA. Although researchers have examined the psychological correlates of exercise behavior among youth, limited research investigating moderators of the theories of reasoned action (TRA; Ajzen & Fishbein, 1980) and planned behavior (TPB; Ajzen, 1985) in this population exists. Therefore, the main purpose of this study was to examine socioeconomic status (SES) as a moderator of the psychological correlates of exercise intention and behavior using the TRA/TPB …

Vascular Function, Physical Performance And Aging, Devon Dobrosielski

LSU Doctoral Dissertations

This is a series of three experiments with brachial artery flow-mediated dilation (BAFMD) as the major outcome variable. The first study examined the temporal response of the brachial artery diameter following forearm occlusion in sixteen young (28±8 years) and fifteen older (85±8 years) men. Following release of the pressure cuff there is a significant reduction in brachial diameter compared to baseline, followed by a rapid increase to a PEAK. When comparing the magnitude of the decrease in diameter and the BAFMD between Young and Old, older subjects demonstrated a blunted response. A significant relation was noted between the magnitude of …

Assessing Ethnorelative Pedagogical Preparedness In Pete Programs, Joe W. Burden

LSU Doctoral Dissertations

Previously, multicultural education literature has highlighted the increase of ethnically diverse students' growth in American public K-12 schools (Articles & McClafferty, 1998; Ladson-Billings, 1994). On the other hand, the literature reveals that many teachers are failing to appropriately exhibit culturally relevant pedagogical competence to accommodate the growth of students of color in American schools (NCDTF, 2004). Oftentimes, this contributes to the development of pre-service teachers that lack culturally relevant pedagogical preparation to teach students of color in American K-12 schools (Burden, Hodge, O'Bryant & Harrison, 2004; Ambrosio, Seguin, & Hogan, 2001). Thus, this study sought out to better understand how …

Quantification Of Muscle Fatigue In Cerebal Palsy And Its Relationship To Impairments And Function, Noelle G. Moreau

LSU Doctoral Dissertations

Three experiments were designed to explore the measurement of muscle fatigue in people with cerebral palsy (CP). The four aims were to 1) develop a feasible and reliable isokinetic protocol to assess muscle fatigue of the knee flexors and extensors in this population, 2) determine if muscle fatigue of the knee flexors and extensors in people with CP differs from subjects without a motor disorder, 3) determine whether muscle fatigue is related to functional measures of activity and participation, and 4) investigate possible contributing factors of muscle fatigue. Results show that muscle fatigue can be reliably assessed through an isokinetic …

The Influence Of Controllability On College Women's Efficacy And Attributions In Physical Activity, Julie Franks Gill

LSU Doctoral Dissertations

There is evidence that individuals’ attributional patterns are important determinants of behavior. Controllability had been identified as an influential dimension of causal attributions. When individuals believe their actions have an effect, or control, on the outcome of an event, they are more likely to engage in a behavior. Contingency of feedback can be used to manipulate perceptions of controllability. The purpose of this study was to investigate the effect of controllability on causal attributions, efficacy, and performance in an exercise setting, using a design that accounts for explanatory styles. It was hypothesized that non-contingent outcomes on an initial task would …

Maximize Muscle Mechanical Output During The Stretch-Shortening Cycle--The Contribution Of Preactivation And Stretch Load, Mianfang Ruan

LSU Doctoral Dissertations

It is well documented that the stretch-shortening cycle (SSC), the most common muscle behavior, enhances muscle mechanical output. Stretch load and muscle preactivation level have been suggested as the two important factors regulating mechanical output. The purpose of this series studies is to systematically examine influences of the preactivation and the stretch load on muscle mechanical output during SSC. In the First study, a two dimensional lower extremity dynamic model was used to evaluate the influence of the approach on mechanical output. The peak summed power during the push-off phase demonstrated a quadratic trend across heights and appeared to be …

Infant Mortality Trends Among Georgia Residents, 1995-2003: Targeting Healthy People’S 2010 Goals, Diana Sturges, Laura H. Gunn, Padmini Shankar, Shrikrishna Shroff

Health Sciences & Kinesiology: Faculty Publications

Population-based trends in infant mortality among Georgia Residents between 1995 and 2003 were assessed on characteristics such as race, birth weight, neonatal and post-neonatal periods, and cause of death. A statistical analysis was conducted to show that the Georgia infant mortality rate (IMR) remained constant throughout the study period and averaged 8.67 per 1,000 live births. The analysis revealed racial disparities, with an IMR ranging from 6.03 in white infants to 13.76 in black infants, with less than one percent (0.86%) change, on average, among the differences between black and white mortality rates across the nine-year period. The disparities were …

Changes In Energy Expenditure With Ingestion Of High Protein, High Fat Versus High Protein, Low Fat Meals Among Underweight, Normal Weight, And Overweight Females., Amy Jo Riggs, Sareen S. Gropper, Barry D. White

Health Sciences & Kinesiology: Faculty Publications

Background: Metabolic rate is known to rise above basal levels after eating, especially following protein consumption. Yet, this postprandial rise in metabolism appears to vary among individuals. This study examined changes in energy expenditure in response to ingestion of a high protein, high fat (HPHF) meal versus an isocaloric high protein, low fat (HPLF) meal in underweight, normal weight, or overweight females (n = 21) aged 19–28 years.

Methods: Energy expenditure, measured using indirect calorimetry, was assessed before and every 30 minutes for 3.5 hours following consumption of the meals on two separate occasions. Height and weight were …

Acute Stretch Perception Alteration Contributes To The Success Of The Pnf "Contract-Relax" Stretch, J. Brent Feland, Sterling C. Hilton, J. Ty Hopkins, Iain Hunter, Ulrike H. Mitchell, J. William Myrer

Faculty Publications

Context: Some researchers have suggested that an alteration of stretch perception could be responsible for the success of the contract-relax (CR) stretch, a stretch technique derived from proprioceptive neuromuscular facilitation (PNF). Objective: This study was conducted to determine if the alteration of the stretch perception is a possible explanation for the range of motion (ROM) gains of the CR stretch. Participants: Eighteen subjects performed two stretches in randomized order: the slow stretch and the CR stretch. Main Outcome Measure: The stretch intensity was controlled. The stretch force was measured and compared between the slow stretch and CR stretch. Results: There …
