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 ...
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) ...
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 ...
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 ...
A Comparison of Lean and Obese Gait Characteristics of Children and Adults During Level Walking
(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 ...
A single dose of metformin improves whole body insulin sensitivity and alters cellular redox state in skeletal muscle of Zucker fa/fa rats
(East Carolina University, 2010)
Energy balance is considered a fundamental requirement of life forms from single cell organisms to higher mammals such as humans. Unfortunately, our species has also discovered the detrimental metabolic responses to excess ...
