5'-AMP-Activated Protein Kinase and Eukaryotic Elongation Factor 2 Response to Resistance Exercise in Young Versus Old Men and Women
Harper, Bradley M. (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 ... -
Cleaved Caspase-3 Response to Acute Resistance Exercise in Young and Old Men and Women : Relationship to Muscle Glycogen Content and 5'-AMP-Activated Protein Kinase (AMPK) Activity
Choplin, Eric Seneca (East Carolina University, 2011)In addition to suppressing protein synthesis and activating protein degradation in skeletal muscle and other cell types, 5'-AMP-activated protein kinase (AMPK) is known to stimulate nuclear apoptosis in non-muscle cells ... -
A Comparison of Lean and Obese Gait Characteristics of Children and Adults During Level Walking
Herring, Cortney S. (East Carolina University, 2010)Increased body mass affects gait kinematics and kinetics in adults. It is however unknown if increased body mass produces similar adaptations in children and adults. The duration of obesity in children is shorter than ... -
Does Minimally Invasive Robotic Surgical Treatment Alter Exercise Tolerance in Patients with Atrial Fibrillation and Mitral Regurgitation at Seven to Eleven Weeks Post-Operative?
Patel, Leena Jayesh (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 ... -
Effect of Acute Exercise or Fasting on Mitochondrial Function and High Fat Diet-Induced Insulin Resistance
Kwon, Oh Sung (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 ... -
Effect of Duodenal-Jejunal Bypass on Skeletal Muscle Insulin Signaling in Goto-Kakizaki Rats
Sloan, Ruben Carnell (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 ... -
Effects of a Before School Physical Activity Program on Physical Activity and On-Task Behavior in Elementary School-Aged Children
Vuchenich, Michelle (East Carolina University, 2010)The prevalence of obesity in children has dramatically increased over the last few decades and physical inactivity has been identified as a main contributor. Schools are an ideal setting for children to engage in physical ... -
Effects of Insulin Sensitivity Modulators on the Mitochondrial Fate of Oxygen in Skeletal Muscle
Kane, Daniel A. (East Carolina University, 2010)Increasingly, reactive oxygen species (ROS) are implicated in the development of insulin resistance. To test the hypothesis that modulators of insulin sensitivity (i.e., metformin, ovarian sex steroids and exercise training) ... -
Effects of Parental Obesity on Fat Metabolism During Submaximal Exercise in Children
Eaves, Audrey Denise (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 - ... -
Exercise effects on physical activity level, self-perceptions, and quality of life of sedentary children, the interaction of BMI, and the association between moderate to vigorous physical activity and psychological variables
Wilson, Kathryn E. (East Carolina University, 2010)The purposes of this study were to (a) examine the relationship of physical activity with global self-esteem (GSE), physical self-worth (PSW), physical self-perceptions, and health related quality of life (HRQOL), and to ... -
Gender Differences in Aerobic and Work Capacity During Plantar Flexion Exercise
Stagner, Lindsay (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 ... -
Impact of Reading for Pleasure Versus School During Exercise on Affective State Responses
Day, Rachel M. (East Carolina University, 2010)Based on the distraction hypothesis, an acute exercise session provides a time out from life stress and serves as an explanation for why exercise potentially improves affect. It is plausible that not all exercise settings ... -
Increased Antagonist Coactivation-Related Hamstring Torque Reduces Maximal Knee Extension Torque in Healthy Old Adults
Gomez, Jonathan R. (East Carolina University, 2010)As humans age, the ability to produce maximal voluntary torque decreases due to muscle atrophy (sarcopenia) and it is also known that advancing age alters the neural control of voluntary movement. One manifestation of the ... -
Influence of Thigh Muscle Forces on Anterior Cruciate Ligament Forces during Single-Leg Landing from Three Different Heights
Bulluck, Jonathan M. (East Carolina University, 2010)Over 200,000 anterior cruciate ligament (ACL) injuries occur every year amounting to billions of dollars being spent on the ACL annually. While the quadriceps muscle produces an anterior shear force on the tibia that ... -
Measured Resting Energy Expenditure Using a Fixed Function Indirect Calorimeter in the Clinical Setting as a Predictor of Success with Weight Change in an Obese Pediatric Population
Henes, Sarah T. (East Carolina University, 2010)The American Dietetic Association (ADA) standard of care for obese adults utilizes indirect calorimetry for calculating caloric targets for weight loss (1). Even though rates appear to be leveling off (2), childhood obesity ... -
Modulation of H Reflex in Response to Voluntary Contraction of the Homologous Muscle in the Contralateral Limb
Motawar, Binal (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
Bikman, Benjamin Thomas (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 ... -
Muscle Work Discrepancy during Incline and Decline Running at Three Speeds
Long, Benjamin L. (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 ... -
NEURAL MECHANISMS CONTRIBUTE TO THE AGE RELATED INCREASE IN METABOLIC COST OF GAIT
