Effects of an After-School Physical Activity Intervention on Physical Activity, Aerobic Fitness, and Body Composition
(East Carolina University, 2012)Low levels of physical activity have been linked to the increased prevalence of obesity in children and adolescents. Federal and local policies to increase the focus on academic time have resulted in decreased physical ... -
Effects of Dietary Leucine Supplementation on Muscle Mass and Markers of Protein Degradation in Overloaded Skeletal Muscles of Young Adult and Aged Rats
(East Carolina University, 2011)The hypertrophic response to overload in fast-twitch skeletal muscle is impaired in aged humans and rats, and upregulation of protein degradation pathways are hypothesized to be a contributing factor. Muscle growth occurs ... -
Effects of Insulin Sensitivity Modulators on the Mitochondrial Fate of Oxygen in Skeletal Muscle
(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 MODERATE AEROBIC EXERCISE ON THE ATTENUATION OF LEAN MASS LOSS DURING RAPID WEIGHT LOSS
(East Carolina University, 2013)Background: Obesity has become a severe issue in the United States, and gastric bypass surgery has been one of the most successful tools to combat the adverse consequences of this disease. The rapid weight loss associated ... -
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 - ... -
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
(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 ... -
Exercise Training Amount and Intensity Effects on Metabolic Syndrome (From Studies of a Targeted Risk Reduction Intervention through Defined Exercise)
(East Carolina University, 2007-12-15)Although exercise improves individual risk factors of the metabolic syndrome (MS), there is little research on the effect of exercise on MS as a whole. The objective of this study was to determine how much exercise is ... -
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 ... -
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 ... -
How do low horizontal forces produce disproportionately high torques in human locomotion?
(East Carolina University, 2008)Although horizontal ground forces are only ~15% of vertical forces, they account for 47% and 33% of the metabolic cost in walking and running. To explain these disproportionately high metabolic costs we hypothesized that ... -
The impact of a repeated bout of eccentric exercise on muscular strength, muscle soreness and creatine kinase.
(East Carolina University, 1994-12)The purpose of this study was to determine if there were any beneficial or detrimental effects regarding delayed onset muscle soreness (DOMS), serum creatine kinase (CK), and maximum concentric strength at 80% of 1-RMconc, ... -
Impact of Hormone Replacement Therapy on Exercise Training-Induced Improvements in Insulin Action in Sedentary Overweight Adults
(East Carolina University, 2008-07)Exercise training (ET) and hormone replacement therapy (HRT) are both recognized influences on insulin action, but the influence of HRT on responses to ET has not been examined. In order to determine if HRT use provided ... -
Impact of Reading for Pleasure Versus School During Exercise on Affective State Responses
(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 ... -
Impaired overload-induced muscle growth is associated with diminished translational signalling in aged rat fast-twitch skeletal muscle
(East Carolina University, 2006-07-01)Impaired overload-induced protein synthesis and growth in aged fast-twitch skeletal muscle may result from diminished responsiveness of signalling intermediates controlling protein translation. Yet, potential age-related ... -
Incorporating a visuomotor skill task with resistance training does not increase strength gains in healthy young adults
(East Carolina University, 2012)Resistance training causes well-documented adaptations in the nervous system and increases maximal voluntary force of healthy human skeletal muscle in the trained and also of the same muscle in untrained limb. It is also ... -
Increased Antagonist Coactivation-Related Hamstring Torque Reduces Maximal Knee Extension Torque in Healthy Old Adults
(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 ... -
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, ... -
The Influence of BMI and Self-Efficacy Levels on the Accuracy in Self-Reported Physical Activity Recall
(East Carolina University, 2011)The purpose of this study was to compare self-reported and objectively measured physical activity levels among college students with different body mass index (BMI) classifications (normal weight and overweight/obese), in ... -
The Influence of Energy Expenditure on Mitochondrial Functions, Oxidative Stress and Insulin Resistance under Metabolic Oversupply Conditions
(East Carolina University, 2011)Mitochondrial respiratory capacity and oxidative stress have been implicated in the development of insulin resistance (IR) and type II diabetes. A causative role of mitochondrial oxidative stress in the etiology of ... -
Influence of Thigh Muscle Forces on Anterior Cruciate Ligament Forces during Single-Leg Landing from Three Different Heights
(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 ...
