Metabolic Inflexibility in Skeletal Muscle With Obesity
(East Carolina University, 2009)The skeletal muscle of obese individuals has a reduced capacity to oxidize lipids. The hypothesis to be tested in this dissertation is that the ability to regulate lipid oxidation in response to lipid exposure is impaired ... -
Modulation of H Reflex in Response to Voluntary Contraction of the Homologous Muscle in the Contralateral Limb
(East Carolina University, 2010)Several studies reported that exercising one limb produces gains in motor output in the same muscle of the un-exercised, contralateral limb. This phenomenon is called cross education. There are also data to suggest that ... -
Modulation of IKKβ with AMPK Improves Insulin Sensitivity in Skeletal Muscle
(East Carolina University, 2008-11)Activation of the insulin receptor substrate (IRS)-1 is necessary for proper transduction of the insulin signal. IRS-1 serine312(human)/307(rodent) phosphorylation, however, results in disruption of this signal and subsequent ... -
More Than Just Letting Them Play: Parental Influence on Women's Lifetime Sport Involvement
(East Carolina University, 2008)This qualitative study uses expectancy-value and life course theories (Giele & Elder, 1998) to examine both the proximal and distal impact of early family socialization on enduring female participation in sport. Seventeen ... -
Muscle Work Discrepancy during Incline and Decline Running at Three Speeds
(East Carolina University, 2009)Introduction: Previous research has explored muscle function during gait and this work has shown that more positive mechanical muscle work is produced in gait tasks that primarily raise the center of mass (incline gait ... -
Muscle work is biased toward energy generation over dissipation in non-level running
(East Carolina University, 2008-12-05)This study tested the hypothesis that skeletal muscles generate more mechanical energy in gait tasks that raise the center of mass compared to the mechanical energy they dissipate in gait tasks that lower the center of ... -
Muscles do more positive than negative work in human locomotion
(East Carolina University, 2007-10)Muscle work during level walking and ascent and descent ramp and stairway walking was assessed in order to explore the proposition that muscles perform more positive than negative work during these locomotion tasks. Thirty ... -
NEURAL MECHANISMS CONTRIBUTE TO THE AGE RELATED INCREASE IN METABOLIC COST OF GAIT
(East Carolina University, 2010)Aging is associated with biomechanical and physiological changes in several organ systems, including neural changes of voluntary movement. One manifestation of age-related changes in neural control of gait is the increased ... -
No difference in the skeletal muscle angiogenic response
(East Carolina University, 2007-11)Ischaemia-induced skeletalmuscle angiogenesis is impaired in aged compared with young mice. In humans, vascular endothelial growth factor (VEGF) mRNA and protein following an acute exercise bout are lower in aged compared ... -
Obese Children Have a Lower Lipolytic Response to an Acute Bout of Exercise When Compared to Lean
(East Carolina University, 2010)Over 17% of American children are obese. These are epidemic proportions considering the associated risk of heart disease and Type 2 diabetes. Excess fat is caused from an imbalance in energy stored versus energy expended. ... -
Paired Effects of Dietary Leucine Supplementation and Overload on Protein Translational Signaling and Hypertrophy in Aged Rat Skeletal Muscle
(East Carolina University, 2012)Sarcopenia is an age-associated disorder that causes loss of skeletal muscle mass, particularly in type II (fast-twitch) muscle fibers. This loss in muscle mass can cause disability, reductions in the quality of life, and ... -
Physical activity across the curriculum: year one process evaluation results
(East Carolina University, 2008-07-07)Background: Physical Activity Across the Curriculum (PAAC) is a 3-year elementary school-based intervention to determine if increased amounts of moderate intensity physical activity performed in the classroom will diminish ... -
Physical Activity, Academic Performance, and Physical Self-Description in Adolescent Females
(East Carolina University, 2009)Despite the many health benefits of being physically active, nearly a quarter of U.S. adults and adolescents report no participation in leisure-time physical activity. It is recommended that children and adolescents ... -
The Physiological and Pathological Role of Mitochondrial Calcium in the Diabetic Heart
(East Carolina University, 2011)Diabetic patients are more susceptible to ischemia/reperfusion injury and cardiac dysfunction likely due alterations in mitochondrial calcium handling. The purpose of this work was to determine if redox-dependent changes ... -
POSITIVE VS. NEGATIVE MUSCLE WORK OF NON-LEVEL WALKING IN LEAN AND OBESE ADULTS.
(East Carolina University, 2010)When walking on non-level surfaces at a constant speed, an individual's total mechanical energy will increase when walking up an incline, and will decrease an equal amount going down a decline. Total muscle work performed ... -
Prediction of Athletic Injury with a Functional Movement Screen
(East Carolina University, 2014)The Functional Movement Screen[superscript]TM (FMS) is a screening tool designed to quantify movement quality. The ability of the FMS to identify individuals likely to be injured has been examined in athletic and military ... -
Proximal vs. Distal Fascicle Behavior within the Biceps Femoris Long Head at Different Muscle Activation Levels
(East Carolina University, 2013)Hamstring strains have been shown to occur more often in the long head of the biceps femoris (BFLH) than the semitendinosus and semimembranosus, with most injuries occurring in the proximal half of the BFLH. Muscle modeling ... -
The Region Specific Influence of Estradiol on In-Vivo Lipolysis in Subcutaneous Adipose Tissue in Overweight-to-Moderately-Obese Premenopausal Women
(East Carolina University, 2012)Premenopausal women demonstrate preferential accumulation of adiposity in the gynoid region, a distribution which shifts towards the abdominal region after the menopausal transition. Although estrogen is implicated as a ... -
Regulation of GLUT4 expression in denervated skeletal muscle
(East Carolina University, 2009-03)Denervation by sciatic nerve resection causes decreased muscle glucose transporter 4 (GLUT4) expression, but little is known about the signaling events that cause this decrease. Experiments were designed to test the ... -
REGULATION OF LIPOLYSIS BY [BETA]-ADRENERGIC ACTIVATION AND EXERCISE IN OBESE AFRICAN-AMERICAN AND CAUCASIAN WOMEN
(East Carolina University, 2012)African-American women (AAW) are twice as likely to be obese as Caucasian women (CW); however, previous in-vitro studies have shown that AAW have higher densities of beta-adrenergic receptors (B-AR) in the subcutaneous ...
