Acute Effects Of Exercise On Cognitive Performances Of Older Adults, R. Pennington, S. Hanna

Journal of the Arkansas Academy of Science

Accelerating rates of structural decline become evident during the third and fourth decades of human life, with disproportionate degeneration occurring in the frontal, parietal, and temporal brain lobes. As the structure of the brain declines, a broad array of cognitive processes involving memory, decision making, and selective attention are reduced as well (Raz 2000, Park et al. 2001). Cardiovascular exercise has been associated with improved cognitive functioning in aging humans, suggesting that increased vascular supply enhances availability of oxygen, nutrients, and other physical entities to nourish the brain. Previous experimentation on older adults revealed significant positive effects of exercise on …

Prescribing Physical Activity To Prevent And Manage Gestational Diabetes, Sheri R. Colberg, Kristin Castorino, Lois Jovanovič

Human Movement Studies & Special Education Faculty Publications

Gestational diabetes mellitus (GDM) is the most prevalent metabolic disorder during pregnancy. Women diagnosed with GDM have a substantially greater risk of developing type 2 diabetes within 5-10 years after delivery, and the risk is increased by excess body weight. Uncontrolled hyperglycemia during pregnancy is potentially harmful to both mother and fetus, resulting in a greater need for Caesarian-section deliveries, delivery of larger infants with more excess body fat, a greater risk of infant death and stillbirth, and an elevated risk of infant hypoglycemia immediately after birth. Fortunately, engaging in physical activity prior to and during pregnancy may lower the …

Relationship Between A Proxy Of Prenatal Testosterone (2d:4d) And Determinants Of Endurance Running Performance, Simon D. Holzapfel

Online Theses and Dissertations

Low ratios of the length of the second finger to the length of the fourth finger in the right (right 2D:4D) and the left hand (left 2D:4D) have been linked to high prenatal testosterone concentrations. Low R-L 2D:4D (subtracting left 2D:4D from right 2D:4D) has been associated with high androgen sensitivity as indicated by low numbers of cytosine-adenine-guanine (CAG) triplet repeats on exon-1 of the androgen receptor gene. Endurance training has led to higher increases in maximal oxygen uptake capacity (VO2max) in men with relatively low numbers of CAG triplet repeats, suggesting a relationship between R-L 2D:4D and VO2max. Moreover, …

Measuring Organizational Member Involvement In Physical Activity Coalitions Across The United States, Daniel Benjamin Bornstein

Theses and Dissertations

Physical inactivity has been labeled a global pandemic with enormous economic, social, environmental, and public health consequences. The vast majority of American adults and youth are insufficiently physically active. Increasing population-levels of physical activity (PA) requires broad social and environmental change. PA coalitions provide the structure through which such broad change can be achieved. An extensive literature on health-based coalitions suggests that coalition success is impacted by coalition members. Coalitions are generally comprised of member organizations. Little is known about the characteristics of PA coalitions and less is known about organizational member involvement in PA coalitions. The purpose of this …

Outsmarting The Brain: Augmenting Motor Training With Non-Invasive Brain Stimulation In Order To Facilitate Plasticity-Dependent, Functional Improvement Within The Motor Cortex, Raymond Joseph Butts

Theses and Dissertations

Brain stimulation techniques capable of optimizing cortical plasticity may provide the key to improved therapeutic techniques and functional outcomes. The primary aim of this dissertation was to examine the potential of motor training (MT) augmented with intermittent theta burst stimulation (iTBS) and anodal transcranial direct current stimulation (a-tDCS). The secondary aim was to investigate whether the training would also be advantageous to older-adults. We hypothesized that right-handed, college-age students exposed to the treatment (n=17) would perform better short-term (directly following MT) and long-term (24 hours and 7 days following MT) on motor-skill retention tests than students receiving sham stimulation (n=14). …

Choice Response Time Differences Between Recently Recovered Concussed And Healthy Student-Athletes, Tiffen Tapia-Lovler

College of Graduate Studies: Theses & Dissertations

Some 1.6 to 3.8 million sports-related concussions occur annually in the United States. Utilization of test batteries and exercise protocols are recommended to ensure athletes recover completely. Many batteries involve response time (RT) tests, which show response time increases post concussion. A major limitation of RT tests is that all are done in static position. Additionally, many studies show a lingering effect on RT. The addition of RT tests to check for lingering symptoms could be beneficial. The purpose of this study was to see if significant differences could be found in RT tests involving dynamic movement between healthy studentathletes …

Motives For Physical Activity And Physiological Variables As Predictors Of Exercise Intentions Following A High Intensity Interval Training Protocol In College-Age Females, Sarah Joseph

College of Graduate Studies: Theses & Dissertations

Recent data collected on college-aged females indicates that more females are classified as insufficiently active and may have little time for physical activity (Ligouri, et al., 2011). High intensity interval training (defined as very short intense intervals, usually above 85% maximum heart rate accompanied by alternated passive recovery periods; HIIT) has become a popular alternative to the more traditional continuous training utilized by individuals due to its time efficiency. In fact, HIIT has been shown to induce many of the same physiological changes as moderate intensity training with less training time. It is possible that college-aged females may benefit from …

Relationship Between Fundamental Movement Skills And Body Mass Index In Rural Elementary Age Children, Mariah L. Bolin

Masters Theses

A factor of how much physical activity a child gets could be determined by the level of mastery of fundamental movement skills that are needed for the establishment of skills used in many forms of adult physical activity. Children who master a number of fundamental movement skills are more likely to be physically active and they also may be more likely to take part in physical activity when being compared to peers with a lesser level of motor skill proficiency. Children who are considered overweight tend to engage less often in physical activities, which in turn may prevents them from …

The use of a foam roller is becoming a popular tool utilized in many settings but there has been …

Examining Articulatory Kinematics Using Diadochokinesis In Concussed And Non-Concussed Individuals, Lindsay Deann Dolan

Open Access Theses & Dissertations

ABSTRACT

Cognitive and communicative deficits associated with traumatic brain injury are an active area of research. However, no research to date has reported on the functionality of motor speech following a concussion. A common tool used to evaluate the motor speech status of potentially impaired individuals is the measurement of the diadochokinetic speech rate. The purpose of this study is to investigate diadochokinetic speech rates in individuals who experience a sports-related concussion. Determining the nature and extent of motor speech involvement post concussion will contribute to the diagnosis, prognosis, and management of recovery. The present investigation will determine; (i) if …

Factors Influencing Glycogen Branching Enzyme Activity In Mouse Liver, Scott Fuller

LSU Doctoral Dissertations

Glycogen is the storage polysaccharide in a spectrum of organisms ranging from yeast to humans. Glycogen has a highly branched structure somewhat resembling a tree or shrub, with the branch points formed by glucose molecules being joined by α 1,6-glycosidic linkages. These linkages are formed by the action of branching enzyme. Branching of glycogen is critical to health, with a lack of branching causing glycogen storage disease type IV, which is fatal in humans by age 2. While glycogen branching enzyme has been studied in clinical medicine, modulation of the enzyme has received comparatively little attention. This dissertation undertook three …

Physical Self-Concept And Gender : The Role Of Frame Of Reference And Social Comparison Among Adolescent Females, Emily Kristin Beasley

LSU Doctoral Dissertations

Quality physical education can positively influence students’ emotional development, specifically their perceptions of competence, self-esteem, and self-concept. Unfortunately, girls often become less engaged and involved in physical education as they grow older and consistently report lower physical self-concepts than males. Physical self-concept is associated with multiple positive outcomes, yet there is only speculation addressing why females report lower physical self-concepts than males in physical education. The overall purpose of this dissertation was to investigate potential explanations for gender discrepancies in physical self-concept among physical education students. One qualitative and one quantitative research study was conducted to address this issue. The …

To Sotl Or Not To Sotl?, Diana Sturges

Health Sciences & Kinesiology: Faculty Publications

Excerpt: "To be, or not to be, that is the question" is one of the most famous lines from Shakespeare’s play Hamlet. As a soliloquy, Hamlet's speech represents a monologue of his thoughts and feelings and addresses existential questions. It is generally accepted that in his speech Hamlet is wondering whether he should choose between life and death. Life seems to be full of hardships, yet there is uncertainty at what lies beyond life, what happens after death? It is assumed that the audience (if there is one) would not hear the speaker, however, Hamlet-the character of the play …
