The Effectiveness Of Using Video Modeling Techniques To Improve Motor Skills For Preschool Children With Autism Spectrum Disorders, Atya Abdullah Hadadi

Theses and Dissertations

Beside the main syndromes of socialization and communication for individuals with autism spectrum disorders, they also have impairments in motor skills, such as ball skills (catching and throwing) and postural stability (standing and walking balance). The main objective of this dissertation is to improve motor skills for preschooler children with ASD through use of video-modeling techniques. A secondary objective of this research was to find a correlation between the development and improvement of ball skills and balance tasks. Twenty-six children with ASD were divided into two groups. Twenty-six children with ASD from 3-5 years old participated in two groups: one ...


The Influence Of Time Spent In Beginning And End-State Postures On Grasp Choice, Rachel Modersitzki Dec 2018

The Influence Of Time Spent In Beginning And End-State Postures On Grasp Choice, Rachel Modersitzki

Undergraduate Honors Capstone Projects

The choice to end comfortably often requires adoption of uncomfortable beginning states, demonstrating that a sequence of movement is planned in advance of movement onset. Many factors may influence the choice of comfortable end-state postures including the greater precision and speed afforded by postures at joint angle mid-ranges (Short & Cauraugh, 1999). There has been no evaluation of the hypothesis that postures are chosen based on minimizing time spent in postures. Typically, the time spent in beginning and end-states are not explicitly constrained, but the end-state posture is likely held for the longer amount of time due to greater precision or ...

The Effects Of An Irregular Surface On Contact Geometry, Shock Attenuation And Metabolic Cost During Running, Alyssa M. Gantz Jan 2016

The Effects Of An Irregular Surface On Contact Geometry, Shock Attenuation And Metabolic Cost During Running, Alyssa M. Gantz

Graduate Theses and Dissertations

With the popularity of non-traditional and off-road race events on the rise, the number of runners encountering trail surfaces has undergone a marked increase in recent years. Despite the growing popularity of trail and off-road running, little research has been done to investigate the effects of running on irregular surfaces. PURPOSE: The purpose was to investigate the kinematic and metabolic effects of running on an irregular surface. We hypothesized that the irregular surface would cause runners to reduce frontal plane foot inversion and increase knee flexion at contact, increasing the metabolic cost of running and shock attenuation. We also examined ...

FITNESSGRAM is the most widely used youth fitness assessment and reporting tool in school physical education programs. It has been adopted by thousands of schools in the United States and is required as a mandated statewide fitness assessment tool in several states. While developed primarily for educational applications, FITNESSGRAM also has utility for research and public health applications. This dissertation summarizes FITNESSGRAM outcomes from two large applications to advance research on youth fitness research and practice. The first application, Texas Youth Fitness Study, involved the evaluation of statewide data collected in the state of Texas as part of mandated school ...


Longitudinal Validity Of The Fnpa Screening Tool To Predict Changes In Weight Status In Children, Karissa Lyn Peyer Jan 2016

Longitudinal Validity Of The Fnpa Screening Tool To Predict Changes In Weight Status In Children, Karissa Lyn Peyer

Graduate Theses and Dissertations

The increasing prevalence of overweight and obesity and the accompanying comorbidities among children and adolescents in recent decades is cause for public health concern. Many factors influence weight status and obesity risk, but little research has examined the influence of the home environment on weight status across different age groups, particularly in longitudinal designs. The Family Nutrition and Physical Activity (FNPA) screening tool is a validated measure of the home environment, but further testing of the tool is needed. The purposes of this dissertation were to 1) compare various versions of the FNPA to evaluate user perceptions and test reliability ...

The Effects Of Different Exercise Regimens On Body Water Compartments In Younger And Older Adults, Lauren Maze

Graduate Theses and Dissertations

Purpose: The purpose of this study was to analyze existing data and compare the effects of an 8-week intervention of either aerobic exercise, resistance exercise, or a combination of both on changes in total body water (TBW), intracellular (ICW) and extracellular (ECW) water volumes and body composition between groups and compared with a non-exercise control group in younger and older adults.

Methods: 69 pre- or stage-1 hypertensive, overweight or obese, and sedentary adults (age 58 ± 7 y) were randomized to one of three training programs: aerobic (AT), resistance (RT), or a combination of aerobic and resistance (COMB), or a non-exercise ...


Estimates Of Persistent Inward Current Decline In Human Soleus Motor Units During Fatigue, Kirby Mendes Jan 2016

Estimates Of Persistent Inward Current Decline In Human Soleus Motor Units During Fatigue, Kirby Mendes

Theses and Dissertations (Comprehensive)

Fatigue is defined as any exercise induced reduction in strength or power, and can be attributed to central and peripheral components. Many central and peripheral mechanisms have been extensively studied, but few studies have looked at the changes in the intrinsic properties of motor neurons and their contribution to fatigue. Persistent inward current (PIC) is an important intrinsic property of motor neurons responsible for setting a large increase in the gain of motor output and may contribute to fatigue. Inhibitory inputs such as reciprocal inhibition (RI) have been shown to turn off PICs and reducing the gain of output. PIC ...


How Do Social Norms Affect Physical Activity And Performance On An Endurance Task?, Keith David Randazzo Jan 2016

How Do Social Norms Affect Physical Activity And Performance On An Endurance Task?, Keith David Randazzo

LSU Doctoral Dissertations

Despite the extensive benefits associated with a physically active life style, less than 50% of US adults engage in recommended levels of physical activity (PA), so finding ways to structure environments to promote PA is an important concern. Social norms, conceptualized as an individual’s perception of peer behavior, provide a framework for exploring factors that influence decisions to be physically active. Although researchers have investigated how social norms influence a variety of behaviors, the PA domain has not been fully explored. The focus of this dissertation is to apply social norms theories to investigate how normative information influences PA ...


The Comparative Effects Of Hot Yoga And Thermoneutral Yoga On Flexibility, Heart Rate, Sweat Rate, And Mood, Hannah Kirkland Campbell Jul 2015

The Comparative Effects Of Hot Yoga And Thermoneutral Yoga On Flexibility, Heart Rate, Sweat Rate, And Mood, Hannah Kirkland Campbell

Theses and Dissertations

Yoga is an ancient Indian philosophy, described as a therapeutic intervention and health maintenance practice that unites the mind and body to aid healing through the combination of physical postures, breathing techniques, and meditation. There is ample research regarding yoga practiced in an environment that is thermoneutral, or in an environment that does not alter the metabolic heat production or evaporative heat loss of people. However, minimal research exists on the increasingly popular form of yoga known as hot yoga, or yoga practiced in an environment that is often humidified and 95° F or warmer. This exploratory study compared the ...


Rearfoot, Mid/Forefoot, And Barefoot Running: Biomechanical Differences Related To Injury, Elizabeth Rose Boyer Jan 2015

Rearfoot, Mid/Forefoot, And Barefoot Running: Biomechanical Differences Related To Injury, Elizabeth Rose Boyer

Graduate Theses and Dissertations

Running is an accessible, inexpensive form of exercise. However, running injuries are common and burdensome. Many runners are curious about switching to barefoot (BF) running or minimalist shoes to avoid injuries, which is commonly associated with rearfoot strikers (runners who land on the posterior third of their foot) landing on the middle or front third (mid- or forefoot strike; FFS). My purposes were to determine if undocumented aspects of FFS and BF running are beneficial or harmful compared to rearfoot striking (RFS), and if any potential benefits of FFS or BF running can be achieved by shortening one’s stride ...


Age-Associated Adaptations In Lower Limb Motor Patterns During Walking And Cycling, Harsh Harish Buddhadev Jan 2015

Age-Associated Adaptations In Lower Limb Motor Patterns During Walking And Cycling, Harsh Harish Buddhadev

Graduate Theses and Dissertations

Muscular strength and power generating ability decline with advancing age. Older adults adapt their lower limb motor patterns to cope with these declines in muscle function. When mechanical demands approach limits of lower limb muscular capacity, motor patterns must be adapted to produce a desired movement. The term “motor pattern” is used to broadly represent the kinematic and kinetic profile of a person accomplishing a given task. Generally, these adaptations involve higher reliance on stronger proximal muscles to compensate for limitations or weakness of distal muscles. Three studies were conducted to examine factors affecting differences between older and young adults ...


The Effects Of Medial And Lateral Wedges On Iliotibial Band Strain During Overground Running, Evan M. Day Jan 2015

The Effects Of Medial And Lateral Wedges On Iliotibial Band Strain During Overground Running, Evan M. Day

Graduate Theses and Dissertations

Background: Iliotibial band syndrome (ITBS) is the leading cause of lateral knee pain in runners. Previous research has theorized that higher ITB strain rate leads to ITBS development. Orthotics are commonly used to correct gait mechanics and may reduce ITB strain and strain rate. The purpose of this research was to investigate how wedge inserts and gender affect kinematics, kinetics, and ITB strain and strain rate during running. Methods: Thirty (15 male, 15 female) participants ran with lateral 7°, lateral 3°, no wedge, medial 3°, and medial 7° wedges. A motion capture system and force platform were used to collect ...


Reimagining Fitness Practice In Schools: An Experimental Study On Self-Perceptions And Motivational Outcomes In Youth, Amanda Beth Mischo Jan 2015

Reimagining Fitness Practice In Schools: An Experimental Study On Self-Perceptions And Motivational Outcomes In Youth, Amanda Beth Mischo

Graduate Theses and Dissertations

BACKGROUND: Physical fitness testing in physical education (PE) is mandatory in several US states, based on the promise that testing will "assist students in establishing lifelong habits of regular physical activity." However, in actuality, the influence of fitness practice for testing, as commonly implemented in schools, on motivational outcomes remains largely unknown. Modifying the experience of fitness practice testing by translating psychological theory into practice may represent untapped potential in the effort to promote physical activity in childhood. Thus, the purpose of the present study is to examine the effect of different structures of fitness practice (traditional versus needs supporting ...


Duration Of Improved Insulin Sensitivity After High Intensity Exercise In Young Overweight Men, Kelsey Quinn Jan 2015

Duration Of Improved Insulin Sensitivity After High Intensity Exercise In Young Overweight Men, Kelsey Quinn

Graduate Theses and Dissertations

Insulin resistance, an impaired ability of the tissues to respond to insulin, is a prevalent health concern in the U.S., with 8.3% of the population diagnosed with diabetes. Numerous studies have found exercise programs increase insulin sensitivity, but research on the effects of high intensity interval training on insulin sensitivity is limited. Of those studies, few have observed the length of the effect of a single bout of high intensity interval training (HIT) on insulin sensitivity to determine the minimal exercise time and frequency that stimulates improved insulin sensitivity. Purpose: This study investigated the length of the effect ...


Independent And Combined Effects Of Aerobic And Resistance Training On Blood Pressure (Art-B), Elizabeth C. Schroeder Jan 2015

Independent And Combined Effects Of Aerobic And Resistance Training On Blood Pressure (Art-B), Elizabeth C. Schroeder

Graduate Theses and Dissertations

The health benefits of aerobic exercise have been well established, with less data existing on the benefits of resistance exercise. Furthermore, most early studies on physical activity and hypertension investigated either aerobic or resistance training alone, and have primarily been done on healthy individuals. Therefore, data on individuals who are hypertensive, overweight or obese, sedentary, and at an increased risk for cardiovascular disease are scarce. Purpose: The purpose of this study was to compare the effects of aerobic training only, resistance training only, and a combination of both on blood pressure and other cardiovascular disease risk factors compared with a ...


Evaluating The Effect Of Switch Pe On Physical Activity And Sedentary Behavior In And Out Of Physical Education Classes, Yoon Ho Nam Jan 2015

Evaluating The Effect Of Switch Pe On Physical Activity And Sedentary Behavior In And Out Of Physical Education Classes, Yoon Ho Nam

Graduate Theses and Dissertations

Physical education (PE) is a key channel to influencing youth physical activity (PA) and sedentary behavior (SB) but it has proven difficult to improve the quality of PE lessons. SWITCH PE is a concept-based PE curriculum that helps shape healthy behaviors in relation to the energy-balanced lifestyle. The purposes of this study are to evaluate (a) whether a SWITCH PE can provide recommended amounts of PA in PE and (b) whether SWITCH PE can impact children’ s daily PA and SB levels. Data were collected from fourth and fifth grade students at four elementary schools in Iowa (with two schools ...


How Does Rescuer Fitness Affect The Quality Of Cardiopulmonary Resuscitation?, Gabe David Lancaster Jan 2015

How Does Rescuer Fitness Affect The Quality Of Cardiopulmonary Resuscitation?, Gabe David Lancaster

Graduate Theses and Dissertations

INTRODUCTION: High quality cardiopulmonary resuscitation (CPR) is crucial for patients experiencing cardiac arrest. CPR quality declines within the first few minutes of a CPR bout. Limited research has examined the extent to which a rescuer's physical fitness predicts high quality CPR performance. It is also unknown how CPR quality is affected during both a realistic duration protocol and when rescuers switch compressors every two minutes, as recommended by the American Heart Association (AHA). The purpose of the present study is to determine the extent to which different measures of physical fitness predict high quality CPR performance when rescuers follow ...
