Body Composition And Carotid Artery Intima-Media Thickness In 12 To 17-Year-Old Adolescents, Jennifer J. Willis

Theses and Dissertations

Background and Purpose—There is controversy in the literature regarding the relationship between intima-media thickness (IMT) and body composition among adolescents. This study investigated the relationship between body fat percentage and IMT, while controlling for height, weight, age, blood pressure, cholesterol, glucose, triglycerides and VO2max in 12 to 17-year-old children.
Methods—111 children (mean age = 14.33 years) participated in this study. Body fat percentage was assessed using dual energy x-ray absorptiometry (DXA). A B-mode, high-resolution ultrasonograph was used to measure the IMT of the right and left common carotid arteries (CCA). Fasting blood tests were performed to obtain blood …

Development Of An Exercise Test To Predict Vo2max In Children And Adolescents, Nathan E. Black

Theses and Dissertations

The purpose of this study was to evaluate the use of nonexercise (N-EX) data, specifically, the Perceived Functional Ability (PFA) and Physical Activity Rating (PA-R) questionnaires, with the treadmill walk-jog-run protocol to estimate VO2max in 12 to 17 year old boys and girls. Ninety-one participants (49 males and 42 females) took part in this study. Data were collected via PFA and PA-R questionnaires, a walk-jog-run submaximal treadmill test, and a maximal graded exercise test (GXT). Data collected included gender, age, height, weight, PFA and PA-R scores, heart rate (HR), treadmill speed, maximal treadmill grade, respiratory exchange ratio (RER), rating of …

A Correlational Study: The Relationship Between Physical Activity Levels, Physical Self-Worth, And Global Self-Worth In High School Physical Education Students, Ashley Danelle Eyre

Theses and Dissertations

The purpose of this study was to determine the relationship between physical activity levels, physical self-worth, and its sub-domains; (a) skill, (b) body attractiveness, (c) fitness and conditioning, and (d) strength, and overall global self-worth in high school students. One-Hundred and sixty-seven students (male = 66;female = 101) from the western United States, ages 13-18, participated in this study. Each participant completed a minimum of four days of physical activity (PA) data collection and completed the self-worth questionnaire. Pedometers were used to collect PA levels, calculating mean step counts, and the Children and Youth Physical Self-Perception Profile (CY-PSPP) was used …

Body Mass Index And Soft Drink Consumption Among Adolescents, Olivia Love Mccord

Theses and Dissertations

Objective: To determine the relationship between body mass index (BMI) and soft drink consumption among adolescents. It is hypothesized that soft drink consumption contributes to overweight and obesity among adolescents.

Background: Research examining the relationship between body mass index and soft drink consumption is inconsistent. Several studies have found a negative association between total sugar intake and BMI; however, others have found a link between sugar-sweetened drinks and obesity. There are no known studies that have controlled for physical activity.

Data and Methods: Data on approximately 225 adolescents were used. Frequency of soft drink consumption, type of milk, and calcium …
