An Examination Of Body Composition Measurement Methods In Children, Robert Kaplan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction . Body-composition methods include underwater weighing (UWW), skinfold thickness (SKF), bioelectrical impedance (BIA), and the BOD POD. Although these techniques are used routinely, each has its inherent limitations, especially in children. Purpose . The purpose of this study was to examine the various methods of body composition in children. Methods . The body composition of 7 boys between the ages of 12-14 (13.1 +/- 1.1 years) was determined using the BOD POD, UWW, SKF, and BIA. Results . Percent body fat estimated from the BOD POD (21.9 +/- 7.8%BF) was not significantly different than the estimated percent fat from …

Effect Of Different Resistance Exercise Methods On Post-Exercise Blood Pressure, Daniel Rodriguez†, Marcos D. Polito‡, Reury F.P. Bacurau‡, Jonato Prestes‡, Francisco L. Pontes Jr‡

International Journal of Exercise Science

The aim of the present study was to evaluate the post-exercise blood pressure (BP) responses to two different methods of resistance exercise (RE, traditional multiple set and tri-set). Young adult men (n = 30, 19.6 &#; 0.7 years old; 76.0 ± 2.7 kg; 178.2 ± 6.7 cm; 90.5 ± 5.8 MBP) with six months of previous experience in RE were selected. The volunteers were randomly assigned into three groups (n = 10, each group): non-exercised control group (CON); multiple set group (MS); and a tri-set group (TRI). The TRI group performed three consecutive exercises (3 sets of 10 repetitions with …

The Use Endocrine Markers To Predict And Monitor Performance In Strengh [Sic] And Power Activities, Jason B. Winchester

LSU Doctoral Dissertations

Hormones are typically considered to be chemical messengers, which are designed to be released from specific cells where they are carried to their target tissues for binding to receptors. It is this binding of a hormone molecule to its specific receptor which allows for an action to occur (Hadley and Levine 2006). Testosterone is the predominant androgen in the majority of mammalian species and is largely responsible for regulation of reproduction and maintenance of sexual function. In addition, in adult mammals, T has multiple other roles including the growth of muscle and bone, hematopoesis, blood coagulation, development and regulation of …

Caffeine Consumption Patterns And Beliefs Of College Freshmen, Gary Eugene Mcilvain

University of Kentucky Doctoral Dissertations

Recently, energy drinks that contain high caffeine content without any age restrictions for purchase, have been introduced into the U.S. market. Caffeine consumption in the U.S. has increased dramatically, resulting in an increase in emergency room visits and calls to poison control centers. This increase in energy drink consumption, along with the traditional coffees, teas, and soft drinks that people consume regularly, have pushed caffeine consumption to new highs in a multi-billion dollar market.

The purpose of this study was to determine (1) the amount of caffeine consumed by a sample of freshmen students at Marshall University, (2) their beliefs …

Optimal Movement Variability: A New Theoretical Perspective For Neurologic Physical Therapy, Nikolaos Stergiou, Regina T. Harbourne, James T. Cavanaugh

Journal Articles

Variability is a natural and important feature of human movement. Using existing theoretical frameworks as a foundation, we propose a new model to explain movement variability as it relates to motor learning and health. We contend that mature motor skills and healthy states are associated with an optimal amount of movement variability. This variability also has form and is characterized by a chaotic structure. Less than optimal movement variability characterizes biological systems that are overly rigid and unchanging, whereas greater than optimal variability characterizes systems that are noisy and unstable. Both situations characterize systems that are less adaptable to perturbations, …

The Effect Of Athletic Training Program Course Progression And Implementation Of Course Progression On First-Time Success Rate On The Board Of Certification Examination, Matthea S. Hungerford

All-Inclusive List of Electronic Theses and Dissertations

Context: For optimal preparation for the Board of Certification (BoC) examination, the environment in which a student learns should be designed to disseminate the appropriate knowledge in a sequenced, timely manner.

Design: Multiple Pearson correlational analyses. Setting: Web-based survey. Patients or Other Participants: Program directors from 31 Commission on Accreditation of Allied Health Education Programs (CAAHEP) accredited entry-level undergraduate athletic training education …

Effects Of Stretching On Jumping Performance, Carisa Chavez

Masters Theses & Specialist Projects

Stretching has been a part of warm-up for a very long time. Some recent research has shown that stretching could possibly hinder performance and others have shown it enhances performance. The purpose of this study was to examine whether stretching has an effect on vertical jump, and if so, how long the effects last. Twenty Western Kentucky students (10 M and 10 F) performed three trials each. There was a non-stretching group, a pre-stretching group and a between-stretching group; each of the subjects performed all three. The stretching protocol included a static stretching routine of the gluteus maximus, hamstrings, quadriceps, …

An Investigation Of Perceived Restrictions On Certified Athletic Trainers Practice, Katy Taake

All-Inclusive List of Electronic Theses and Dissertations

The purpose of this study was to identify the frequency and nature of perceived restrictions by certified athletic trainers (ATCs) and to determine the frequency of perceived restrictions for each practice setting within states that have legislation. This was a qualitative-descriptive study performed with a web-based survey. 10,000 ATCs receiving electronic mail from the National Athletic Trainers' Association (NATA) were invited to participate in this study. 1158 subjects participated in the study, and 724 subjects (295 female and 429 male; age=33.2 ± 8.3yrs) remained after exclusions. A webbased survey was created to evaluate perceived restrictions. Inorder to establish face validity …

Effects Of Creatine Supplementation On Muscular Strength And Power Development In Well-Trained Football Players, Josef D. Mcquain

Theses, Dissertations and Capstones

The Effect Of Horseback Riding Activity On The Tibialis Anterior, Vastus Lateralis, And Rectus Abdominis Of A Paraplegic, Laurie A. Price

Masters Theses

Horses are now being used in various programs under various conditions. The use of horses for therapy and recreation for the physically and mentally disabled first began in Germany and Switzerland. The United States now has many schools and different riding programs as well.

Riding seems to be especially beneficial to those with neurological impairments. Treatment of paraplegia is very limited but recreational activities are advancing. The use of the horse is beneficial for paraplegics emotionally as well as physically. Measurements and evaluations of these benefits are lacking. This project analyzes and measures the physical benefits of horseback riding on …

The Relationship Between Oxygen Debt Size And Blood Ph Change During Recovery From Exercise On The Bicycle Ergometer And Treadmill, Timothy J. Falconer

Masters Theses

It was the purpose of this study to investigate the relationship of oxygen debt and blood pH change during the recovery from exercise.

For this study, ten male members of the Eastern Illinois University track team were chosen as subjects on the basis of their levels of physical condition.

The subjects were tested on three different occasions. The first test for all subjects was a fifteen minute resting oxygen consumption. Then depending upon random selection, the subjects ran on a treadmill and on another test day rode a bicycle ergometer, or vice versa. Preceding each exercise a pre-exercise micro-blood sample …
