EFFECTS OF A 16 WEEK PHYSICAL ACTIVITY INTERVENTION ON SERUM C-REACTIVE PROTEIN CONCENTRATIONS IN 8-11 YEAR OLD AFRICAN AMERICAN AND CAUCASIAN CHILDREN.
(East Carolina University, 2013)
C-reactive protein (CRP) is a non-specific marker of systemic inflammation that has been associated with heart disease, obesity, and metabolic disorders in adults and children. Previous physical activity interventions have ...
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) ...
The Meaning and Cultural Context of Physical Activity as Perceived by Physically Active, Rural African American Women
(East Carolina University, 2010)
Background - The health problems of overweight and obesity are growing concerns in the United States and in many parts of the world. At the time of this study, African American women had the highest mortality and obesity ...
Comparison of Scaled vs. Ultrasound Based Musculoskeletal Models on Knee Muscle Moments During Single-Leg Squatting
(East Carolina University, 2012)
Muscles produce force, resulting in moments about a joint, causing movement of the body. Muscle forces are estimated with a Hill-type model incorporating four parameters; optimal fiber length (OFL), tendon slack length, ...
Influence of training history and contraction velocity on hamstring muscle coactivation during maximal effort knee extension
(East Carolina University, 2012)
When a muscle produces voluntary force, muscles on the opposite side of the joint, the antagonists, are also activated. While coactivation of the knee flexors during knee extension is presumed to increase joint stability ...
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 ...
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 ...
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 ...
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 ...
Effects of a Before School Physical Activity Program on Physical Activity and On-Task Behavior in Elementary School-Aged Children
(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 ...
