Oxygen Uptake Efficiency Slope And Functional Physical Performance In Elderly Adults, Scott Eric Fuller
Oxygen Uptake Efficiency Slope And Functional Physical Performance In Elderly Adults, Scott Eric Fuller
LSU Master's Theses
Background: The Oxygen Uptake Efficiency Slope (OUES) attained during submaximal treadmill exercise is a reliable index of cardiorespiratory capacity in older adults. This investigation compares OUES values derived during treadmill walking and performance of the Continuous Scale Physical Function Performance test (CS-PFP). Method: A Cosmed portable metabolic cart was used to collect breath gases in 36 older adults (age: 81.8 +/- 7.8 years). Twenty-one subjects performed both the incremental treadmill test and the CS-PFP while an additional 15 subjects performed the CS-PFP, only. Results: The regression of log Ventilation vs. VO2 reveals similar correlations for the CS-PFP and treadmill …
Autonomic Nervous System Modulation Of The Heart Following A High Carbohydrate Liquid Meal, Calynn Davis Bunol
Autonomic Nervous System Modulation Of The Heart Following A High Carbohydrate Liquid Meal, Calynn Davis Bunol
LSU Master's Theses
The involvement of the sympathetic nervous system in the pathology of obesity has long been a debate among researchers. Various methods of capturing the resting sympathetic activity as well as the response of the sympathetic activity elicited by the introduction of a meal or a bout of exercise in both lean and obese individuals have been investigated. This study examined the autonomic modulation of the heart following a high carbohydrate liquid meal in various body types. Twenty-five females with body mass indexes [weight (kg)/height2(m)] ranging from 19.3-39.5 were grouped according to relative basal energy expenditure adjusted for lean …

L-Glutamine Supplementation: Effects On Recovery From Exercise, Tavis Joseph Piattoly
LSU Master's Theses
Clinical evidence supports the use for exogenous glutamine in the maintenance of muscle mass and immune system function in critically ill patients. Relatively little research has examined the benefits of glutamine for athletes engaged in heavy exercise training, despite a possible link between overtraining and glutamine. PURPOSE: To examine the influence of Glutamine on time to exhaustion and power after a prolonged bout of exercise. METHODS: Twelve men (Age: 19 to 30y) involved in cycle training were asked to participate in the study. All participants performed a Symptom-Limited Graded Exercise Test (SL-GXT) using the Astrand Cycle protocol. On a subsequent …
Hemodynamic And Ocular Responses To Caloric Stimulation And Age-Related Disparities, Melissa J. Deveer
Hemodynamic And Ocular Responses To Caloric Stimulation And Age-Related Disparities, Melissa J. Deveer
LSU Master's Theses
Age-related declines in vestibular function affect balance and coordination in older adults. Of perhaps equal importance, but less understood, are the potential implications of vestibular degeneration on cardiovascular homeostasis. Recent evidence suggests that the semi-circular canals, a section of the vestibular system, may be involved in the vestibulosympathetic reflex (VSR), but the extent to which the aging of the semi-circular canals interferes with cardiovascular homeostasis is unknown. Activation of the intact VSR results in increases in tonometric blood pressure (TBP) and heart rate (HR) as well as decreases in cardiac output (Q) and pre-ejection period (PEP). The purpose of this …

Physical Function And Health Related Quality Of Life In Culturally Diverse Elders: Evidence Of Environmental Press, Robyn M. Bossier
LSU Master's Theses
The purpose of this project was to identify group differences in physical function and HRQL between older adults living in different environments, and to compare information from these groups to data from a random sample of elders pulled from the general population. METHODS: Seventy-eight older adults were evaluated for physical function using the continuous-scale physical functional performance test (CS-PFP) and HRQL using the SF-36 v.2. Subjects were 26 predominantly African American participants (LOW group; age 72.2 ± 8.1 years), 26 Caucasian adults (HIGH group; age 77.6 ± 4.8 years), and 26 adults selected from a population-based study (POP group; age …
Health And Lifestyle Profiles Across The Lifespan: Results From The Louisiana Healthy Aging Study, Madlyn Irene Frisard
Health And Lifestyle Profiles Across The Lifespan: Results From The Louisiana Healthy Aging Study, Madlyn Irene Frisard
LSU Doctoral Dissertations
Aging and age related disease affects individuals differently. One possible explanation could be free radical production varies among individuals and this variation determines the aging process and the progression of disease. The purpose of this study was to test whether nonagenarians have a relatively low metabolic rate when compared to younger individuals and whether this low metabolic rate is associated with lower levels of oxidative stress and less incidence of disease. Resting metabolic rate (RMR), markers of oxidative stress to lipids, proteins, and DNA, components of the metabolic syndrome, and physical activity level were measured in 3 groups of individuals …

Examining The Relationships Between Ability Conceptions, Intrinsic Motivation, Presistence And Performance, Weidong Li
LSU Doctoral Dissertations
The purpose of this study was to examine the relationships between ability conceptions, intrinsic motivation, persistence, and performance using an interaction approach. The phase-one study revealed that participants who were more oriented toward incremental ability beliefs were likely to be more intrinsically motivated. For those who were more intrinsically motivated, they displayed more persistence and obtained better performance scores. Participants who were highly intrinsically motivated had lower performance scores as they were more oriented toward incremental ability beliefs. The phase-two study showed that participants who were more oriented toward incremental views were more intrinsically motivated, which provided evidence supporting the …

The purpose if this investigation was to examine injury rates among college athletes with a diagnosed psychological condition/mental disorder. Participants were drawn from a pool of 440 male and female intercollegiate athletes (ages 18-26 years). All subjects with a psychological disorder were then identified (n=38) and placed in the diagnosis group. A second group was then selected, which consisted of matched pairs of athletes without a psychological diagnosis. Twelve sports were represented in the sample population with an equal number of male (n=26) and female (n=12) participants in each group. The athletic training database was examined via query to identify …
Evaluation Of The Relationship Between Venous Function And Post Exercise Oxygen Consumption Recovery Kinetics, Eric Joseph Tisdell
Evaluation Of The Relationship Between Venous Function And Post Exercise Oxygen Consumption Recovery Kinetics, Eric Joseph Tisdell
LSU Master's Theses
Excess post-exercise oxygen consumption (EPOC) has been attributed to metabolic, hemodynamic, neuroendocrine, and pulmonary factors. In one particular study, Barclay (J Appl Physiol 1986;61(3):1084-90) suggested that a lower rate of fatigue and hyperperfusion following a bout of exercise was due to a mechanism other than increased oxygen and substrate delivery. Interestingly, few studies have examined the influence of venous function on EPOC. The purpose of this study was to examine the relationship between measures of vascular function and EPOC. Measures of vascular function and VO2 recovery kinetics were examined in 20 individuals [age=22+2.41 yrs]. Nondominant forearm arterial inflow, venous capacitance …
Effects Of Aerobic And Anaerobic Training Protocols On 4000m Track Cycling Time Trial, William Mathieu Cheramie
Effects Of Aerobic And Anaerobic Training Protocols On 4000m Track Cycling Time Trial, William Mathieu Cheramie
LSU Master's Theses
The aim of this study was to determine whether performance in a 4000m individual pursuit could be significantly influenced by training protocols that are solely based in either aerobic/distance training, or anaerobic/sprint training. Faina et al., (1989) and Neuman et al. (1992) have found, using professional track cyclist that there appears to be a split in energy pathways used to perform the event. Their results indicate that 20% of the workload is achieved via anaerobic metabolism and the remaining 80% are achieved through aerobic metabolism. Group #1, followed a training protocol modeled after repeated, short duration, (<1:30.00s/1000m), high intensity sprinting. This particular training protocol may serve to utilize a greater proportion of its allotted time by generating beneficial metabolic adaptations that may possibly improve the subjects performance in the 4000m individual pursuit. Group #2, trained primarily through aerobic means, followed the "more traditional" training method for such an event. This protocol consisted of cycling intervals of distances proportionally longer (>4000m) than that …

Influence Of Venous Emptying On Reactive Hyperemic Blood Flow, Zeki Bahadir
Influence Of Venous Emptying On Reactive Hyperemic Blood Flow, Zeki Bahadir
LSU Master's Theses
Recent work by Tschakovsky & Hughson (Am J Physiol Heart Circ Physiol 279: H1007, 2000) indicates that venous emptying serves as a stimulus for vasodilation. This suggests the importance of recognizing the potential influence of venous volume on reactive hyperemic blood flow (RHBF) following occlusion. Purpose: To examine the influence of venous emptying on RHBF. Methods: Non-dominant forearm in-flow, venous capacitance and outflow were examined in 21 individuals [age=23±2.27y]. Forearm arterial inflow, venous capacitance, and outflow were obtained two times using strain gauge plethysmography. Forearm blood inflow was estimated at rest and following 5 min of upper arm occlusion. Forearm …

Brachial Artery Dimensions, Flow-Mediated Reactivity And Physical Function In Older Adults, Christina M. King
LSU Master's Theses
Human aging is associated with deterioration in physical functional ability. The causes are complex and multifactorial, but are presumed to include the presence and extent of cardiovascular disease. Purpose: To examine the associations between brachial artery (BA) dimensions, flow-mediated dilation (BAFMD) and physical function in 28 older adults (age: 84.6±10.9, range 66 to 98 yrs). Methods: High-resolution ultrasonography was used to measure BA diameters at rest and following 5min of forearm occlusion. Physical function was assessed using the Continuous Scale-Physical Function Performance (CS-PFP) test. Results: Pearson correlation revealed that BAFMD (r =-.39), and all physical function parameters of the CS-PFP …
The Effectiveness Of Videotape Feedback In Sport: Examining Cognitions In A Self-Controlled Learning Environment, Justin Menickelli
The Effectiveness Of Videotape Feedback In Sport: Examining Cognitions In A Self-Controlled Learning Environment, Justin Menickelli
LSU Doctoral Dissertations
Providing videotape feedback (VTFB) as a form of knowledge of performance (KP) to learners is a common instructional tool in teaching and coaching. VTFB has attracted renewed attention and various “laundry lists” of recommendations (e.g., provide VTFB immediately following performance, use frequently, vary camera angles) on VTFB implementation (e.g., Franks & Maile, 1991; Trinity & Annesi, 1996). Furthermore, researchers have begun exploring the cognitive variables which serve to mediate the impact of VTFB (e.g., Hebert, Landin, & Menickelli, 1998; Menickelli, Landin, Grisham, & Hebert, 2000). Recent research has focused on two key issues: VTFB provided in a self-controlled learning environment …
Students' Construction Of The Body In Physical Education, Laura Azzarito
Students' Construction Of The Body In Physical Education, Laura Azzarito
LSU Doctoral Dissertations
Recently, physical education researchers have been concerned about the results of national studies reporting young people's low level of participation in physical activity and health problems associated with inactivity. In general girls are less active than boys, and youth from low socioeconomic classes are less active and are more likely be unhealthy than middle or upper class youth. Blacks have the highest risks of health problems and the highest levels of physical inactivity. Among a number of recommendations included in Healthy People 2010, physical education has been identified as a fundamental site for addressing today's challenges. According to physical education …

Arm Crank Power And Hyperammonemia In Respones To L-Aspartic Acid Supplementation, William W. Edwards
LSU Doctoral Dissertations
PURPOSE: To examine the effect of L-Aspartic Acid (L-Asp) supplementation on short-term arm-crank power (i.e. W·min-1) and exercise-induced hyperammonemia in two gender-specific investigations. METHODS: The male investigation (MALE) used nine highly-trained intercollegiate water polo players (WP) and nine moderately-trained college students (MOD); the female investigation (FEM) used 18 recreationally-trained college students. All exercised to exhaustion on two occasions following counterbalanced double-blind ingestion of 12.5g x 2 of L-Asp or placebo (P). The warm-up phase began at 25 W·min-1 and increased in 25 W·min-1 stages every 30 seconds (constant 100 rpm). Performance began (i.e. the subjects turned …
Collective Efficacy: A Framework For Understanding Classroom Teacher's Perceptions Of Integrating Physical Activity, Melissa Ann Park
Collective Efficacy: A Framework For Understanding Classroom Teacher's Perceptions Of Integrating Physical Activity, Melissa Ann Park
LSU Doctoral Dissertations
Children’s physical inactivity is becoming an important health concern, and it has been suggested by professionals that school programs can be important in the effort to increase activity levels. Physical education specialists cannot achieve the goal of significantly increasing children’s activity in isolation, and it is apparent that whole school programs at the elementary level have the potential to foster active lifestyles. If those programs are to be successful, all school personnel must play a role, so it is important to find ways to facilitate their involvement. The purpose of this study was to use collective efficacy as a framework …

The Effect Of Scaffolding Movement Challenges On Students' Task-Related Thoughts And Performance, Paul Bernard Rukavina
LSU Doctoral Dissertations
The purpose of the study was to examine the influence of teaching approaches on thoughts and practice behaviors of students, and how those thoughts and behaviors affect transfer of learning. First, a self-report instrument for assessment of cognitive processes that meditate motor skill outcomes was validated. The cognitive processes included prior knowledge usage, self-efficacy, critical thinking and attention-concentration. University students who had taken a physical activity class (N=409) completed the questionnaires. Three out of the initial four subscales were confirmed as fitting the data. In a university golf activity class, students were assigned into three groups for instruction to learn …
Physical Function And Quality Of Life In The Very- And Oldest-Old: Gender Differences, Kellye A. Ferachi
Physical Function And Quality Of Life In The Very- And Oldest-Old: Gender Differences, Kellye A. Ferachi
LSU Master's Theses
Age is associated with deterioration in physical function (PF) and health-related quality of life (HRQL). Recent investigations suggest that a decrease in function may have a greater impact on perceived activities of daily living (ADL) competency in women than in men. The purpose of this investigation was to test the hypothesis that the association between PF and HRQL among older adults is influenced by gender. We examined 108 older adults aged 60 years or older, for PF (Continuous Scale-Physical Function Performance test (CS-PFP10) and Functional Status Index (FSI)) and HRQL (SF-36). In order to address this question we assigned subjects …
Six-Month Follow-Up Of A Primary Care Managed Weight Loss Program For Overweight And Obese African-American Women, Lee A. Marsh
Six-Month Follow-Up Of A Primary Care Managed Weight Loss Program For Overweight And Obese African-American Women, Lee A. Marsh
LSU Master's Theses
Obesity is the number one public health concern in the United States, and is more prevalent in African-American women and those from lower socioeconomic groups. However, many primary care physicians do not feel confident in their ability to assist patients in weight management. Thus the challenge for physicians is to provide patients better assistance with weight management. The purpose of the study was to examine the efficacy of a primary care-managed weight loss program on weight reduction and cardiovascular fitness in overweight/obese women. Participants were randomized to intervention (n=54; Age: 44+12 yrs) or standard care (n=62; Age: 44=12yrs) and followed …

Gender Differences In Participation Of Physical Activities: A Comprehensive Model Approach, Kay Gordon Daigle
LSU Doctoral Dissertations
The purpose of this study was to examine the interrelationships among gender, perceptions of peer, parent, and teacher support, perceived value and meaningfulness, perceived competence, and the intention to be physically active within a proposed model. Female and male students (N=801) enrolled in a traditional multi-activity physical education class responded to a 52-item questionnaire addressing the constructs in the model. Structural equation modeling, using LISREL, was used to identify the relationships among the constructs. Gender differences emerged in this model through direct paths as well as indirect paths among these variables. Girls were more influenced than boys by their perceptions …
Using Self-Determination Theory To Understand African American Women's Physical Activity Patterns, Joan B. Landry
Using Self-Determination Theory To Understand African American Women's Physical Activity Patterns, Joan B. Landry
LSU Doctoral Dissertations
Physical inactivity is a major health risk factor in our society. Women and minority populations are especially at risk with regard to physical inactivity. This three-part study employed quantitative and qualitative methodologies to investigate physical activity behaviors in middle aged and older African American women. This population was chosen because African American women are the least active segment of our society. In the first phase, a quantitative approach was used to investigate relationships between Self-Determination and the Stage of Change for physical activity in a sample of 105 African American women. This study provided validation for using this theoretical approach …

Arterial And Venous Adaptations To Short-Term Handgrip Exercise Training, Mahmoud Awad Alomari
LSU Doctoral Dissertations
Four studies on vascular and exercise physiology are presented in this document. The 1st study examined the relationships between measures of fitness and FVF in 55 young [22.6 ± 3.5 years] adults. Estimated VO2peak correlated with arterial inflow (Ainf) [r=0.54; p=0.012] and resting venous outflow (Vout) [r=0.56; p=0.016]. Lastly, HG strength was associated with Vcap [r=0.57; p=0.007] and Vout [r=0.67; p=0.001]. The 2nd study examined the relationship between FVF and exercise tolerance (ExT) in 20 patients with HF [age: 59 ± 13 years] and 10 age-matched controls [age: 51 ± 16 years. The ExT was measured as the maximum …

Vagal Modulation Of The Heart And Central Hemodynamics During Dynamic Handgrip Exercise And Forearm Occlusion Following Forearm Exercise Training, Heidi A. Kluess
LSU Doctoral Dissertations
The purpose was to examine the cardiovascular response to an acute bout of handgrip exercise before and after non-dominant arm exercise training. 19 people participated in 16 sessions of exercise training and 16 participants acted as controls (age: 20±1yrs). Blood flow measurements were taken at rest and following 3-min of forearm occlusion (RHBF) using plethysmography. Pneumotachometer, ECG, and blood pressure data were continuously collected during three testing conditions (spontaneous breathing (SB1: 5min), handgrip exercise (0.5hz) at 60%MVC with 50mmHg of pressure on the arm (H60+50mmHg: 5 min), and forearm occlusion (FAO: 3min)). Data were analyzed for respiratory rate, mean R-R …
Reliability Of Wavelet Analysis Of Heart Rate Variability During Rest And Exercise, Deborah Jean Stone
Reliability Of Wavelet Analysis Of Heart Rate Variability During Rest And Exercise, Deborah Jean Stone
LSU Master's Theses
The reliability of wavelet analysis (DWT), of heart rate variability during rest and exercise was examined for this study. All twenty-three participants visited the lab on two separate occasions no less than four weeks apart. All twenty-three participants were subjected to the spontaneous breathing (SB1), and HG60 exercise condition. Of those twenty-three participants, nine performed the HG20 exercise condition as well. It was found that during the SB1 condition, the R-R intervals were fairly reliable between days. However, the reliability of all the HRV parameters (SDNN, spectral components and wavelet components) were quite poor. Interestingly, however, during HG20, the reliability …
Discrimination Of Cardiac Health And Disease By Assessment Of Heart Rate Variability: Wavelet Vs. Fast Fourier Transformation, Jusonda Leray Derouen
Discrimination Of Cardiac Health And Disease By Assessment Of Heart Rate Variability: Wavelet Vs. Fast Fourier Transformation, Jusonda Leray Derouen
LSU Master's Theses
The autonomic nervous system (ANS) modulation of the heart is of clinical importance because of its relevance to risk of life threatening arrhythmic events. Decomposition of heart rate variability (HRV) has been used to quantify ANS control of the heart. The traditional method for frequency analysis has involved the use of fast Fourier transformation (FFT). However, heart rate data typically violate assumptions of the FFT. Therefore, the assessment of HRV may benefit from other, potentially more suitable, mathematical approaches. For example, the discrete wavelet transformation (DWT) appears to have promise with respect to its ability to discriminate between healthy and …
