5'-AMP-Activated Protein Kinase and Eukaryotic Elongation Factor 2 Response to Resistance Exercise in Young Versus Old Men and Women
(East Carolina University, 2009)It has been shown that skeletal muscle 5'-AMP-activated protein kinase (AMPK) phosphorylation and/or activity is more greatly elevated in response to resistance exercise or loading in aged rats, and that eukaryotic elongation ... -
Effects of Parental Obesity on Fat Metabolism During Submaximal Exercise in Children
(East Carolina University, 2009)The aim of the present study was to compare fat metabolism during submaximal exercise in children with a morbidly obese parent - (COP) (BMI [greater than or equal to] 40 kg/m²) to children with relatively lean parents - ... -
Does Minimally Invasive Robotic Surgical Treatment Alter Exercise Tolerance in Patients with Atrial Fibrillation and Mitral Regurgitation at Seven to Eleven Weeks Post-Operative?
(East Carolina University, 2009)In the current study, we examined if exercise tolerance was going to be reduced in atrial fibrillation and mitral valve regurgitation patients post a minimally invasive surgery seven to eleven weeks when compared to ... -
Chronic low-frequency rTMS of primary motor cortex diminishes exercise training-induced gains in maximal voluntary force in humans
(East Carolina University, 2009)Although there is consensus that the central nervous system mediates the increases in maximal voluntary force (maximal voluntary contraction, MVC) produced by resistance exercise, the involvement of the primary motor cortex ... -
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 ... -
Effect of Duodenal-Jejunal Bypass on Skeletal Muscle Insulin Signaling in Goto-Kakizaki Rats
(East Carolina University, 2009)Gastric bypass surgery (RYGBP) for the treatment of obesity has proven to clinically reverse type 2 diabetes mellitus. RYGBP involves both gastric reduction and bypass of the proximal small intestine. Duodenal-Jejunal ... -
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 ... -
Gender Differences in Aerobic and Work Capacity During Plantar Flexion Exercise
(East Carolina University, 2009)Maximal oxygen consumption (VO2max) is lower in females compared to males during traditional whole body, systemic exercise. These differences in VO2max between men and women are still present even after correcting for ... -
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 ... -
Effect of Acute Exercise or Fasting on Mitochondrial Function and High Fat Diet-Induced Insulin Resistance
(East Carolina University, 2009)A high-fat diet leads to an accumulation of lipid in skeletal muscle, and the development of both mitochondrial dysfunction and insulin resistance. Recently, our lab reported that lipid overload leads to elevated ... -
Assessing Children's Physical Activity in Their Homes: The Observational System for Recording Physical Activity in Children-Home
(East Carolina University, 2009)The present study describes the development and pilot testing of the Observation System for Recording Physical Activity in Children-Home version. This system was developed to document physical activity and related physical ... -
Intramuscular Lipid Metabolism, Insulin Action and Obesity
(East Carolina University, 2009-01)With the increasing prevalence of obesity, research has focused on the molecular mechanism(s) linking obesity and skeletal muscle insulin resistance. Metabolic alterations within muscle, such as changes in the cellular ... -
Social and Environmental Factors Associated with Preschoolers' Non-sedentary Physical Activity
(East Carolina University, 2009-01)The two-fold purpose of the investigation was (1) to describe with direct observation data the physical activity behaviors and the accompanying social and environmental events of those behaviors for children in preschools; ... -
Increased Secretion and Expression of Myostatin in Skeletal Muscle From Extremely Obese Women
(East Carolina University, 2009-01)OBJECTIVE- Obesity is associated with endocrine abnormalities that predict the progression of insulin resistance to type 2 diabetes. Because skeletal muscle has been shown to secrete proteins that could be used as biomarkers, ... -
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 ... -
A sex-specific relationship between capillary density and anaerobic threshold
(East Carolina University, 2009-04)Although both capillary density and peak oxygen consumption (VO2) improve with exercise training, it is difficult to find a relationship between these two measures. It has been suggested that peak VO2 may be more related ... -
Effect of exercise intensity and volume on persistence of insulin sensitivity during training cessation
(East Carolina University, 2009-04)Effect of exercise intensity and volume on persistence of insulin sensitivity during training cessation. J Appl Physiol 106: 1079â 1085, 2009. First published February 5, 2009; doi:10.1152/japplphysiol.91262.2008. The ... -
Factors Related to Objectively Measured Physical Activity in Preschool Children
(East Carolina University, 2009-05)This study examined correlates of objectively measured physical activity (PA) in a diverse sample of preschool children (age 3–5 years; n=331). Accelerometer min·hr−1 of moderate-to-vigorous physical activity (MVPA) and ... -
The Intensive Diet and Exercise for Arthritis (IDEA) trial: design and rationale
(East Carolina University, 2009-07-28)Background: Obesity is the most modifiable risk factor, and dietary induced weight loss potentially the best nonpharmacologic intervention to prevent or to slow osteoarthritis (OA) disease progression. We are currently ... -
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 ...
