Nutrition Treatment For Hiv Wasting: A Prescription For Food As Medicine, Ann Y. Mcdermott, Abby Shevitz, Aviva Must, Susan Harris, Ronenn Roubenoff, Sherwood Gorbach

Kinesiology and Public Health

The optimal nutrition approach for the promotion of weight gain in HIV-infected adults with wasting remains unclear. Previous dietary interventions report minimal success and provide inadequate information regarding the counseling approach, contact time, session format, and issues addressed with the subject. The methods we report were incorporated in a 12-week intervention trial for the reversal of HIV-wasting. Methods: All subjects involved in the intervention trial for the reversal of HIV-wasting received weekly, customized, one-on-one counseling and an oral nutrition supplement (480 kcal/d with 30 g protein). The nutrition aims were to (1) increase caloric intake to surpass daily energy requirements …

Role Ambiguity In Sport Teams, Mark A. Eys, Albert V. Carron, Mark R. Beauchamp, Steven R. Bray

Kinesiology and Physical Education Faculty Publications

The general purpose of the present study was to examine the nature of role ambiguity in sport teams and to explore the construct validity of the operational definition of role ambiguity developed by Beauchamp, Bray, Eys, and Carron (2002). Role ambiguity was operationalized as a multidimensional construct (Scope of Responsibilities, Behavioral Responsibilities, Evaluation of Performance, and Consequences of Not Fulfilling Responsibilities) that occurs in two contexts, offense and defense. Consistent with the a priori hypothesis, perceptions of role ambiguity exhibited some degree of within-group consistency and group-level variability, but most of the variance in role ambiguity was seen at the …

Cutaneous Blood Flow In Type 2 Diabetic Individuals After An Acute Bout Of Maximal Exercise, Sheri R. Colberg, Henri K. Parson, D. Robb Holton, Tanja Nunnold, Aaron I. Vinik

Human Movement Studies & Special Education Faculty Publications

OBJECTIVE - We previously demonstrated a positive association between chronic aerobic exercise and dorsal foot skin blood flow during local heating in type 2 diabetic individuals. Thus, we hypothesized that a prior acute bout of maximal exercise would also have positive effects on postexercise blood now.

RESEARCH DESIGN AND METHODS - Subjects consisted of 32 individuals with type 2 diabetes and 26 nondiabetic control subjects further subdivided based on their physical activity status diabetic exerciser (DE), diabetic sedentary (DS), control exerciser (CE), or control sedentary. Dorsal foot cutaneous blood flow was measured noninvasively by continuous laser-Doppler assessment at baseline and …

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

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 …

Three-Dimensional Tibiofemoral Kinematics Of The Anterior Cruciate Ligament-Deficient And Reconstructed Knee During Walking, Anastasios D. Georgoulis, Anastasios Papadonikolakis, Christos D. Papageorgiou, Argyris Mitsou, Nikolaos Stergiou

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

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

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 …

Use Of Heart Rate Reserve And Rating Of Perceived Exertion To Prescribe Exercise Intensity In Diabetic Autonomic Neueropathy, Sheri R. Colberg, David P. Swain, Aaron I. Vinik

Human Movement Studies & Special Education Faculty Publications

Objective- Individuals with diabetic autonomic neuropathy (DAN) exhibit an increased resting heart rate but depressed maximal heart rate. Thus, the purpose of this study was to examine the validity of using either percent of heart rate reserve (HRR) or a rating of perceived exertion (RPE) scale to prescribe exercise intensity in diabetic individuals both with and without DAN.

Research Design and Methods-The subjects consisted of 23 individuals with type 2 diabetes, ages 45-75 years, with (DAN; n=13) or without (No DAN; n=10) clinical signs of DAN, as assessed by heart rate variability using the expiration-to-inspiration ratio of the …

The Effect Of Environmental Context On Performance Outcomes And Movement Coordination Changes During The Learning Of Complex Motor Skills, Jennifer Johnson Jeansonne

LSU Doctoral Dissertations

Four experiments presented here investigated the task demand relationship of intertrial variability (IV) and regulatory conditions (RC), on the outcome and movement changes that occurred with dart throwing practice. The four tasks included: (1) a stationary target with one location (closed w/no IV), (2) a stationary target with five possible locations (closed w/IV), (3) a moving target with one movement pattern (open w/no IV), (4) a moving target with five possible movement patterns (open w/IV). After each throw, the X, Y coordinates of the dart and the target were recorded to calculate radial error (RE). Kinematics was recorded using an …

Hydrodynamic Stability Of Swimming In Ostraciid Fishes: Role Of The Carapace In The Smooth Trunkfish Lactophrys Triqueter (Teleostei : Ostraciidae), Ian K. Bartol, Morteza Gharib, Daniel Weihs, Paul W. Webb, Jay R. Hove, Malcolm S. Gordon

Biological Sciences Faculty Publications

The hydrodynamic bases for the stability of locomotory motions in fishes are poorly understood, even for those fishes, such as the rigid-bodied smooth trunkfish Lactophrys triqueter, that exhibit unusually small amplitude recoil movements during rectilinear swimming. We have studied the role played by the bony carapace of the smooth trunkfish in generating trimming forces that self-correct for instabilities. The flow patterns, forces and moments on and around anatomically exact, smooth trunkfish models positioned at both pitching and yawing angles of attack were investigated using three methods: digital particle image velocimetry (DPIV), pressure distribution measurements, and force balance measurements. Models …

Nitric Oxide Synthase Inhibition Does Not Affect Regulation Of Muscle Sympathetic Nerve Activity During Head-Up Tilt, Jian Cui, Rong Zhang, Thad E. Wilson, Sarah Witkowski, Craig G. Crandall, Benjamin D. Levine

Exercise and Sport Studies: Faculty Publications

To test the hypothesis that systemic inhibition of nitric oxide (NO) synthase does not alter the regulation of sympathetic outflow during head-up tilt in humans, in eight healthy subjects NO synthase was blocked by intravenous infusion of NG-monomethyl-L-arginine (L-NMMA). Blood pressure, heart rate, cardiac output, total peripheral resistance (TPR), and muscle sympathetic nerve activity (MSNA) were recorded in the supine position and during 60° head-up tilt. In the supine position, infusion of L-NMMA increased blood pressure, via increased TPR, and inhibited MSNA. However, the increase in MSNA evoked by head-up tilt during L-NMMA infusion (change in burst rate: 24 ± …

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 …

Spanning Set Defines Variability In Locomotive Patterns, Max J. Kurz, Nikolaos Stergiou, Daniel Blanke

Journal Articles

The purpose of the investigation was to use the spanning set methodology to quantify variability in locomotive patterns and to compare this method with traditional measures of variability. Subjects ran on a treadmill while sagittal plane kinematic data were collected with a high-speed (180 Hz) camera. Changes in variability were evaluated as the subject ran barefoot and in shoes. Mean ensemble curves for the knee angle during the stance period were created for each condition. From these curves, traditional measures of variability were calculated using the coefficients of variation (CVs), and the mean deviation (MD). Spanning set vectors were defined …

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 VO_2peak 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 …

A Comparison Of Youth Participation Motives In Organized Sports, Kirsty L. Carrihill

College of Graduate Studies: Theses & Dissertations (1964–2006)

Youth participation in organized physical activity has increased by more than 5 million in the last decade (Smith & Smoll, 2002). Of the 48 million youth 8 to 16 years old in the United States, 20 million participated in organized sport (Gould & Petlichkoff, 1998; Seefeldt & Ewing, 1997; Smith & Smoll, 2002). Currently, the average age for youth to begin participating in organized sports in, or outside of, school is 11 years old (Klint & Weiss, 1986; Smith & Smoll, 2002). Although participation rates have increased, there are significant numbers of youth who drop out of sport. Over one-third …

Life Values In Youth Sport: A Qualitative Analysis, Carla J. Schmitt

College of Graduate Studies: Theses & Dissertations (1964–2006)

A qualitative analysis was used to examine the life values gained and enhanced through participation in youth soccer from the player, coach, and parent perspectives. Nine players, nine coaches, and nine parents were interviewed for this study. Participants were placed in groups according to classification and availability, and participants not available for the group times, were individually interviewed. The interview guides consisted of 11 questions, and two separate guides were used, one for players and one for coaches and parents. All interviews were hand, audio, and video recorded. Triangulation, involving the primary researcher and two additional researchers familiar with qualitative …

The Prevalence Of Disordered Eating Behaviors Among Sorority Versus Non-Sorority Women, Angela Lynn Guzman

College of Graduate Studies: Theses & Dissertations (1964–2006)

Eating disorders among college women is a serious psychological problem. Disordered eating behaviors were examined and diagnosed at a mid-sized university in southeast Georgia. The target group of this study was university sororities. The purpose of this study was to examine sorority versus nonsorority women to determine if there was a higher prevalence for those involved in sororities to develop disordered eating behaviors.

Surveys were distributed to both sorority and non-sorority women to determine the prevalence of disordered eating behaviors among each group. A quantitative, quasi-experimental design was used in conjunction with the Eating Attitudes Test (Gamer & Garfmkle, 1979). …
