An Accurate Vo2max Non-Exercise Regression Model For 18 To 65 Year Old Adults, Danielle I. Bradshaw Dec 2003

An Accurate Vo2max Non-Exercise Regression Model For 18 To 65 Year Old Adults, Danielle I. Bradshaw

Theses and Dissertations

The purpose of this study was to develop a regression equation to predict VO2max based on non-exercise (N-EX) data. All participants (N = 100), aged 18-65 years old, successfully completed a maximal graded exercise test (GXT) to assess VO2max (mean ± SD; 39.96 mL∙kg-¹∙min&sup-1; ± 9.54 mL∙kg-¹∙min-¹). The N-EX data collected just before the maximal GXT included the participant's age, gender, body mass index (BMI), perceived functional ability (PFA) to walk, jog, or run given distances, and current physical activity (PA-R) level. Multiple linear regression generated the following N-EX prediction equation (R = .93, SEE = 3.45 ...

Ten subjects had not worn a NKS and five subjects had worn a NKS.

After completing all IRB approved documentation subjects underwent a test trial of each of the three testing methods. Subjects were randomly assigned a number that determined if the subject began the test trial with or without a NKS ...


The Osteogenic Effects Of 12 Weeks Of Oral Supplementation Of Androstenedione In Middle-Aged Men., Troy Matthew Wills Dec 2003

The Osteogenic Effects Of 12 Weeks Of Oral Supplementation Of Androstenedione In Middle-Aged Men., Troy Matthew Wills

Electronic Theses and Dissertations

Recent evidence suggests that declining bone mineral density (BMD) in males is related to declining circulating estrogens. The majority of endogenous plasma estrogens in males result from peripheral aromatization of plasma androgens. Thus, it was hypothesized that dietary supplementation with an aromatizable androgen (androstenedione) may stimulate increases in BMD.

BMD (measured by dual energy x-ray absorptiometry) and biochemical markers of bone turnover (1, 25 OH2 Vitamin D, calcitonin, deoxypyrodinoline, and parathyroid hormone) were assessed before and after 12 weeks of dietary androstenedione supplementation (200 mg/d). Twenty-four volunteers were randomized into either an androstenedione supplementation or placebo groups. Study volunteers ...

It would be of benefit to coaches in the sport of alpine skiing to be able to use a field test to assess the physiological readiness of the alpine ski racers they work with. At the junior level, alpine skiing in the United states consists of four events today . These events are the ...


Profiling Employees Participation In Employer Sponsored Fitness Programs In Maine, Wendy-Jo Berube May 2003

Profiling Employees Participation In Employer Sponsored Fitness Programs In Maine, Wendy-Jo Berube

Electronic Theses and Dissertations

Comprehensive health promotion and disease management programs have evolved significantly over the last two decades in both large and small work sites. Research over this time period has yielded plenty of evidence proving health promotion programs can produce tangible outcomes. Studies have repeatedly demonstrated that comprehensive work site health promotion programs can lower employee health care and insurance costs, decrease absenteeism, and improve job performance and productivity. Despite the well-known benefits of regular exercise, previous research has also shown that participation and adherence rates in work site health promotion programs have been unsatisfactory. This study was conducted to profile employee ...

The Relationship Between Fitness-Based Incentive Programs And Exercise Adherence In A Corporate Fitness Facility, Elwood D. Moore

Electronic Theses and Dissertations

Experts agree that habitual exercise is beneficial to health and essential in the primary prevention of coronary heart disease and its associated risk factors. Despite this knowledge, adherence to an regular exercise regimen remains the major problem in the health and fitness industry. Reports estimate greater than 70% of the adult population in the United States do not participate regularly in physical activity. In contrast to the commercial fitness world where membership and profit continue to be the primary directives of the industry, corporate fitness programs are concerned with recruitment and adherence and consistently and exponentially increasing participation to justify ...

After each throw, the X, Y coordinates of the dart and the target were recorded to calculate radial error (RE). Kinematics ...


Collective Efficacy: A Framework For Understanding Classroom Teacher's Perceptions Of Integrating Physical Activity, Melissa Ann Park Jan 2003

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 ...


Physical Function And Quality Of Life In The Very- And Oldest-Old: Gender Differences, Kellye A. Ferachi Jan 2003

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 Jan 2003

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 ...

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 ...


Using Self-Determination Theory To Understand African American Women's Physical Activity Patterns, Joan B. Landry Jan 2003

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 ...

A Comparison Of Youth Participation Motives In Organized Sports, Kirsty L. Carrihill Jan 2003

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

Legacy ETDs

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 of all participants between the ages of 10 and 17 years of age withdraw from sport every year (Linder, Johns, & Butcher, 1991). Past research has shown there were gender differences in reasons for participating in sports and that boys were more likely than girls to participate in sports (Ewing, 1996). The purpose of this study was to investigate participation ...
